Configuring the PC’s Parallel Port
Note: Most new computers have ECP set as default. Re-configure port only if
communication with tester does not work or if the port is not set to ECP.
Computer Bios Settings
The parallel port on the PC used with MTA for Windows must be set up in
order for MTA to acquire data. The parallel port must be configured as an
ECP parallel port in the computer’s BIOS or on the parallel port card.
Consult the PC’s manuals for instructions on how to configure parallel
ports.
Rebooting the computer is necessary for BIOS setting modification. Using
the computer specific keystroke from your PC’s manual, check the BIOS
settings prior to Windows operating system restarting. This specific
keystroke enables the BIOS program, which is used to setup the parallel
9
Doc #: 71-009-001 Rev 1
port. This keystroke varies from one computer to another. Many computers
use “Del”, “Esc”, or the “F10” key. Most computers in use today use the
BIOS written by Award or Phoenix Technologies. Modification instructions
for BIOS settings can be obtained from their associated web sites. They
can be reached at www.award.com and www.phoenix.com.
Installing MTA for Windows 98/ME/2000/XP
To install MTA for Windows, insert the install CD into the computer’s CDROM drive, the install process should start automatically. If computer does not
have the auto-run feature enabled for the CD drive, run setup.exe from the CD.
The install program self guides through the installation process. The files
installed include the MTA.exe, dynamic link libraries (.dll) from Microsoft that
allow MTA for Windows to run, Microsoft Jet Database Engine dll’s, and a
folder for saving test data. The Dll’s are Microsoft’s and only install if nonexistent or an older version is found.
Note Windows 2000/XP installs: Baker has written a kernel driver based on
the Microsoft’s parallel.sys driver. The MTA for Windows installation program
automatically installs the Baker driver in the c:\winnt\system32\drivers folder.
The driver is called BICParallel.sys. It is loaded upon booting the computer. In
order for this driver to install the profile used must have administrative rights.

The Big Idea
The MTA software works by performing pre-configured tests on pre-configured
motors. The pre-configured tests are called Test ID’s. A pre-configured motor is
called a Motor ID. The Motor ID is stored in the MTA’s database along with the
Test ID to be used when testing that motor. Additional information about the
motor such as the manufacturer, serial number, horsepower rating, frame size,
speed, operating voltage and current is also stored in the Motor ID. New motors
can be entered into the database or existing motors can be updated.
To view test results for a given motor or to perform a test on a motor, it must
first be selected from all the other motors in the MTA’s database. The left of the
display is used to find and select a motor. The right of the screen is used to view
test result data and run tests.
The Test ID consists of all test parameters to be used when performing tests on a
motor. Details such as test voltages, pass or fail criteria, and test times are
contained in a Test ID. These Test ID’s are named and defined by the user.
There are already several Test ID’s created by Baker Instrument Company for
several different machines. Usually, the most important parts of a Test ID are
the test voltages. Therefore, a Test ID is named after the operating voltage of the
motor. Several motors can share a single Test ID. For example, all 480 volt
motors can use the same Test ID.
Starting MTA Software
To start MTA, locate and
double click the MTA
icon on the computer’s
desktop.
The
MTA
software will start and
present a window giving
the opportunity to create a
new database, select the
most
recently
used
databases, or browse for
more databases.
Fig 2.1: Selected Database
13
Doc #: 71-009-001 Rev 1
After selecting a database, the following window appears:
Fig 2.2: Selected Database
The main MTA window is split into two panes. The left pane contains three
different tabs that facilitate browsing through the motors in the database: the
Explore Tab, the Motor ID Tab, and the Route Tab. The right pane contains
three more tabs, which allow the viewing of test results and acquisition of test
data.
Finding Motors
The left side of the opening screen is used to navigate through the motors within
the opened database. Three methods are
provided: an Explore Tab where the motor
location is shown in a three level “Tree View”,
Fig 2-3: Finding Motors
a Motor ID Tab where a alphabetical list of
Motor ID’s can be used to locate a motor by
typing the first few characters of the Motor ID, and a Route Tab where
predefined lists of motors can be used, such as in predictive maintenance.
14
Doc #: 71-009-001 Rev 1
The Explore Tab
The Explore tab offers a tree structure to assist
selection of a particular Motor ID. The two upper
levels of the tree correspond to the location and
building that the physical motor is housed.
Location and Building are the default tree labels
but are changeable labels for the motor location
fields. The lowest level is the Motor ID. For
example, in the view below the selected Motor ID,
CnVyr23BLine2-22R, is at the “Willow Ridge”
plant, Unit 22R. By clicking on a Motor ID, that
motor’s data is recalled and becomes the current
motor. Expand a motor location by clicking on the
plus sign or contract a location by clicking on the
minus sign.
Fig 2-4: Explore Tab
The Motor ID Tab
The Motor ID list box contains all motors from the
database in alphabetical order. In the edit box,
located above the list, will be the currently selected
Motor ID. Location of a Motor ID can be done in
two ways within this tab. The first method allows
the operator to begin typing the needed Motor ID
in the edit box. The list will automatically scroll to
the nearest Motor ID that begins with the typed
characters. For example by typing in the letters
“Cn”, in the example to the left the
Cnvyr23Bline2-22R Motor ID would be
highlighted. If this is the needed Motor ID double
click on that Motor ID (or click the Display
button) and it would become the currently selected
motor. The second method is to simply scroll
down in the list until the Motor ID is found.
Double click on the Motor ID or highlight the Motor
ID and click the Display button to select the desired
Motor ID.
15
Doc #: 71-009-001 Rev 1
Fig 2-5: Motor ID Tab
The Route Tab
The Route tab allows construction of individual lists of Motor ID’s for routing
purposes. As seen in the example to the left the “Spring Outage” list is selected.
This list has four motors associated with it. The electrical technician does not
have to search the whole database for the four motors to be tested during the
spring outage.
This tab also allows editing and printing of the routes. Click on the Edit Route
button to evoke the editor. The editor allows Add, Rename, and Delete of
routes. It also allows add, remove and change the order of the Motor ID’s on a
list. See example dialog box Fig 2-7.

the bottom of the panel is
Fig 2.8: Data Tab
selected: a Nameplate view, an
Application view, a Results
Summary View, a Surge view, a PI view, and a Step Voltage Test view. If a
Step Voltage Test was performed on an AWA, the test data can be reviewed on
the MTA software.
18
Doc #: 71-009-001 Rev 1
Data Tab, Nameplate View:
The Nameplate view contains the nameplate data on each motor in the database.
The first field is the Motor ID, which is used by the MTA program to uniquely
identify the motor. Required fields are the Motor ID, and the two motor location
fields. In the example to the right, the location fields are Plant and Unit. The
labels of these two fields are user definable. The default values are Location
and Building. To change the field descriptions do so by selecting the ViewOptions-Changeable Labels menu item. The location fields are used in the
Explore tab to help locate a motor. All other fields in the Nameplate view are
optional.
Fig 2-9: Data Tab, Nameplate View
Note: Several of Baker’s industrial customers have found having all fields filled
in greatly helps in their preventive maintenance programs by providing one
place where their plant’s motor data is kept. Likewise, Baker’s motor shop
customers find recording the complete nameplate information is a required task
when working with their customer’s motors.
The Nameplate view allows for the adding of new motors, updating existing
motors and deleting motors from the database.

the respective rounded check boxes on the left side of the window.
The Temperature Test provides a place where temperature can be entered
manually. Temperature can be entered in either °C or °F. Entered at test time, it
is used to temperature correct coil resistance values per IEEE 118 and insulation
resistance values per IEEE 43/95.
Fig 2-18: Resistance Enable
The Resistance Test has several options associated with it. The motor may have
Wye or Delta winding configurations. The Wye or Delta configuration is
entered in the Nameplate window. The resistance values may be uploading
from Baker tester (DR series only) or acquired by some other means and
manually entered into the software.
By Checking the Max Delta R (%) box, the resistance values will have their
“percent spread” calculated at the end of the test. If the percent spread is outside
the number entered in the edit box, the resistance test will show a “DELTA R”
failure.
Fig 2-19: Temperature Enable
The acquired resistance values may be temperature corrected by checking the
Temperature Enable check box.
27
Doc #: 71-009-001 Rev 1
“Corrected to” temperature is set to the IEEE 118 recommendation of 25°C
however, it can be changed. The constant used to correct resistances is known
as the “IEEE 118 constant” and is 235.4 for copper or 224.1 for aluminum.
Note: A Temperature must be entered in order to get corrected resistances.
A motor that does not have a resistance reading within a Target Resistance range
may also be failed by checking the Target Corrected Resistance check box and
entering appropriate resistances. The application will compare corrected
resistance readings to the Target Corrected Resistance at the end of the test,
determining if the resistances are within tolerance.
Note: Only temperature corrected values will be used in determining if values
are within the specific tolerance.
The lower portion of the Temperature/Resistance dialog consists of three
columns. The first is measured resistance values, the second is temperature
corrected resistance values, and the third column is calculated coil resistance.
Fig 2-20: Test Results
The DR series tester acquires resistance data by hooking the tester to a computer
with the MTA for Windows software installed. Perform the resistance test with
the tester. When testing is completed, leave the tester in the resistance screen
and click on the Up Load button on the Temperature/Resistance Dialog. The
MTA for Windows will acquire the resistance data for all leads, calculate the
temperature corrected values (if temperature was entered) and calculate the coil
resistance.
Note: The data to be uploaded must be present on the tester’s resistance screen.
Measurements merely present on the screen and not yet saved to memory are to
be acquired by pressing the Up Load button. To acquire data saved to memory
use the Acquire Stored Records button on the Test View.
28
Doc #: 71-009-001 Rev 1
If using a non-R series digital tester or have other equipment that takes the
resistance measurement, it can be manually entered. If temperature
compensation is needed enter the temperature and click the ANALYZE button
to calculate the corrected resistance values and coil resistance. This will also
calculate the delta resistance percent which is the maximum value minus the
minimum divided by the average.
Regardless of how the resistance measurements were acquired, once the
measurements are obtained, the software will calculate the temperature corrected
resistances and display them. The individual coil resistances will be calculated,
if possible. If not possible, the software will display a message indicating a
solution to the coil resistance could not be found
Megohm/PI/HiPot Configuration/Data Acquisition Dialog
Fig 2-21: Megohm/PI/HiPot Config
Clicking the DC tests Config/Acquire Data button on the Tests view causes the
DC Tests dialog to be displayed. The dialog in fig. 2-21- is used to acquire real29
Doc #: 71-009-001 Rev 1
time megohm, PI and HiPot data. All three of these tests should be thought of a
single type of test. The Megohm test is the first test to be run, followed
immediately by a PI test, and continuing into a HiPot test. Therefore, a single
set up screen for these three tests is used to configure each test.
This dialog is used to setup test parameters and to acquire real-time data. In the
upper left corner of the dialog is where test enable, test voltages, minimum
Megohm readings, and test times are entered. In addition to DC test parameters,
the temperature can be enabled and entered without having to enter the
resistance screen when not taking resistance values.
Each test may be run individually by pressing the appropriate test button located
in the upper center of the dialog, or all selected tests can be run by pressing the
Run Selected Tests button.
The right side of the screen is a display of the real time voltage, current, and the
insulation resistance reading during the DC tests. The voltage and current will
be displayed as slider bars. Below the slider bars are real time numerical
outputs of the voltage and current.
Surge Configuration/Data Acquisition Dialog
Clicking the Surge tests Config/Acquire Data button on the Tests view causes
the Surge Data Acquisition dialog to appear.
Target Voltage
is located in the
upper left corner.
The surge target
voltage is
traditionally set
to twice the
operating voltage
plus 1000.
The top center of
the screen shows
a series of
checkboxes that
determine
Pass/Fail criteria
for the surge test.
The L-L EAR
(%) checkbox
30
Fig 2-22: Surge Test Dialog
Doc #: 71-009-001 Rev 1
sets the maximum Lead-to-Lead Error Area Ratio (EAR) that is allowed
between the different leads. This is set to 10% as a default. This option should
not be turned on if testing a motor with a rotor installed. If it is absolutely
necessary to use the L-L EAR with the rotor installed, increase the tolerance to
avoid nuisance trips. The increase in EAR tolerance with installed rotors makes
the use of this feature a poor detector of a turn-to-turn insulation problem.
Fig 2-23: Surge Test Setup
The P-P EAR (%) sets the maximum Pulse-to-Pulse Error Area Ratio that will
be allowed for the test. This parameter helps identify turn-to-turn faults. If the
pulse-to-pulse EAR % is greater than the entered tolerance, the MTA for
Windows will flag a “PPEAR” error. The remaining three columns (L1, L2, and
L3) will show real time numbers for the specific lead while the test is running.
These numbers will become visible during the test. Top number will indicate
the current P-P EAR and the bottom number is the maximum P-P EAR percent.
When P-P EAR (%) is turned on, voltage should be ramped slowly and
controlled.
The Test-Ref EAR (%) edit box is used to set a pass/fail criteria when
comparing the surge waveforms from the test to a previously stored Reference
Test.
The 4 buttons on the right side of the screen will run a
surge test if pressed. Clicking the Lead 1 button will
start the acquisition of the surge waveform on lead 1
only, likewise for the Lead 2 and the Lead 3 buttons.
The Surge All Leads button will automatically
sequence through Lead 1, Lead 2, and Lead 3 as if each
button was pressed individually.
Fig 2-24: Run Surge

Doc #: 71-009-001 Rev 1
The peak voltage reached for each lead tested is displayed on the middle right of
the screen. The L-L EAR values shown correspond to the measured Lead-toLead Error Area Ration between the three leads during the test.

The Trending Tab
Pressing the Trending tab brings up a trending graph that charts acquired data.
Information such as resistance, megohm values (temperature corrected and
uncorrected), and HiPot leakage currents can be graphed over time in order to
get an idea of the long term status of a motor’s insulation.
Fig 2-27: Resistance Trend Graph
Resistance
There are three different types of Resistance data that can be trended, Balance,
Line-to-Line, and Coil. Selecting one will bring up a graph similar to Fig 2-40.
Resistance measurements are against time and show very little variation over the
test interval. Each of the three leads is shown in its own color. Each data point is
indicated by a square, diamond or triangle marker. Hovering the mouse pointer
over any of the data point symbols will display the value, test date and time for
that point to popup. This feature allows for easy identification of the test record
33
Doc #: 71-009-001 Rev 1
for that point. By clicking the Markers checkbox the markers can be hidden or
unhidden.
Fig 2-28: Megohm Trending Screen
Insulation Resistance/Megohm
By checking the Megohm button, the megohm data is graphed. In the example
shown below the Megohm reading fluctuates between 1246 and 1275 Mohms –
acceptable values, while the current remains constant. Hovering the mouse
pointer over any of the data points brings up a box indicating the value of the
point and test date/time for the corresponding test record in the database.
Note: When trending Megohm values, the temperature corrected values should
be used and not the uncorrected values. Both values are available to the
software. Sometimes it is not possible to acquire the temperature of a motor
when testing due to inaccessibility of the motor.
34
Doc #: 71-009-001 Rev 1
HiPot
Pressing the HiPot button brings up a graph of the HiPot leakage current data
and has the same features as the Megohm trending graph.
PI
Pressing the PI button displays the graph trending the PI ratio versus time and
has similar features to the other trending graphs.
Relative Humidity
Checking Relative Humidity will cause the tool tips to display the RH% entered
at test time. Hover over a data point will cause the tool tip to display Time/Date
Stamp value of the point and RH%.
Special Software Trending Features
There are occasions
when only a certain
time period of data is
desired to be
displayed or some
invalid points need to
be “thrown out”.
There are two ways in
which to select data
points. The first
method is when the
trending graph is
displayed. Hold the
Fig 2-29: Megohm Trend
left mouse button and
drag and draw a box
around the points to be displayed. See Fig. 2-29. When the left button is
released, the graph will automatically re-scale and display the points inside of
the drawn box. To reset the graph click on the Reset button and all points will
be displayed.
35
Doc #: 71-009-001 Rev 1
The second method is to choose points from a list of all test dates/times. By
pressing the Select Dates button, a window pops up showing the entire test dates
and times as well as a spreadsheet style view of the data. All of the data can be
Fig 2-30: Trending-Select Dates Screen
selected or just specific tests selected. Most often this feature will be used to
exclude a test that contains known bad data that might be, for example, acquired
in a test that was aborted. To select or deselect dates, use the same type of
selection techniques used to select files in Windows Explorer: left click to select
a single record; left click the first record, press the shift key and click on the last
record to select a range; within a selected range, press the ctrl-key and click to
remove a unwanted record from the selection.
Additionally, all of the records on this window can be exported to a commadelimited file for later importing into a spread sheet. In this manner, data can be
analyzed using the customers tools in any way desired. To create the comma
delimited file, select the test date/time to be exported or select none and all will
be exported, then click on the Print to File button, enter a file name and the
application will create a comma delimited file that can later be imported to a
spreadsheet. This dialog will also print out all the data in the list box to a
printer. Click on Print List to print all selected data.

Doc #: 71-009-001 Rev 1
The following chapter will go through an example setup just as an operator
would if a motor was to be tested for the first time. The first thing to do is create
a Motor ID that uniquely identifies the motor – this example will use a 460V
Delco motor. Next, a Test ID will be created for this motor and assigned to the
Motor ID. Then the test will be ran and the results reviewed. Finally, reports will
be printed.
The motor for this example is a Delco 460V, three phase, Wye wound, induction
motor and has the following typical data on its nameplate:
Model: 2G2104
Frame: 213
Serial: B-95
Insulation: B
Amb: 65oC
V:
460V
A:
4.2A
HP:
3
RPM: 1765
Hz:
60
Code: J
SF:
1.0
Des:
B
NEMA NOM EFF: 84
Duty Cycle : Cont
From this information, we will fill out the Motor ID Nameplate form.
Creating a Motor ID
Under the Data tab - Nameplate on the right half of the screen, the Motor ID
information is displayed for the selected motor from the left hand Explore tab.
In this case the CirPump3233-22L is chosen. Pressing the Add button clears the
fields of the Nameplate view. In these data fields, the nameplate information for
the Delco motor is entered. See Fig. 3-1.
39
Doc #: 71-009-001 Rev 1
Fig 3.1: Test ID's
Note: There are more data fields
available than are contained on the
nameplate. Only those items that
are on the nameplate are filled in.
Enter a unique identifier for the Motor ID. For this example use “Delco-B-9522L” as the Motor ID. Plant location is “Willow Ridge” and Unit location is
“Unit 22L”. Fill in the rest of the fields from the nameplate data previously
given. After all data is entered click on the Save button to add the new Motor
ID to the database.
After the Save button is clicked, a Select Test ID dialog will appear. At this
time you will need to assign a Test ID to the newly created motor. In this
40
Doc #: 71-009-001 Rev 1
example, we will select the 480V/woPI Test ID – next we will create a new Test
ID and assign the new Test ID to this Motor ID.
Once the Test ID is selected, click on the OK button. The new Motor ID,
Delco-B-95-22L, is displayed in the tree to the left along with all the other
motors.
At this point the Motor ID, Delco-B-95-22L, has been created. The next step is
to create a Test ID and assign it to this motor.
Creating a Test ID
Fig 3-2: Creating a Test ID
Press the Tests tab. Notice there is already a Test ID assigned in the Test ID
drop down box. For this example, we will add a new Test ID.
To add a blank Test ID:
1.
On the Tests Tab, check the
.
41
Doc #: 71-009-001 Rev 1
2.
Enter the password. (Note: If this is the first time to edit Test ID’s you
will need to set the password by clicking on the Change Password
button and entering a password then click on Set Password.) Click
OK, once the application has accepted your password, the Save, Add,
and Delete buttons will appear and the voltage class dropdown list will
be enabled.
3.
Click on the Add button, the Create New Test ID dialog box appears.
4.
Click on the Add Blank Test ID radio button.
5.
Enter the Test ID, Delco_460/wPI, for this example.
Fig 3-3: Test ID Input
6.
Using the dropdown box select a Target Motor Voltage Class. For
this example, choose the existing voltage class of 460. If it does not
exist you can create a new one by typing 460 in the edit box of the
dropdown list.
7.
If you entered a new voltage class type, in a description and click on
Add Voltage Class button. You will be asked if you want to create a
new voltage class, click OK.
8.
Click OK; this will close the Create New Test ID dialog.
42
Doc #: 71-009-001 Rev 1
Fig 3-4: Test Screen
9.
The new Test ID will be displayed and all tests are turned off.
10. Turn on all of the tests by clicking the left most column of ON/OFF
radio buttons. The Tests view will resemble Fig. 5-4.
11. Proceed to the next section, Configure Temperature/ Resistance.
Configure Temperature/Resistance
1.
The Temperature and Resistance Tests share the same setup screen.
Click on Config/Aquire Data button under Temperature/Resistance
Tests heading. The Temperature/Resistance Test dialog will be
displayed.
43
Doc #: 71-009-001 Rev 1
Fig 3-5: Temperature/Resistance Test Parameters
2.
Click on the Temperature Enable check box. MTA for Windows will
accept a temperature range of range of -32°C to 250°C.
3.
Click on the Resistance Enable check box to turn on the resistance
test. The Delco motor in this example is wye wound, which is
indicated on the screen and can be changed on the motor’s Nameplate
Tab.
4.
Check the Max Delta R (%) check box, setting it to 10%. If the spread
of resistance readings are more then 10% MTA for Windows will fail
the motor.
5.
Since temperature is enabled, the Correct to check box is checked and
defaults to 25°C and the copper’s IEEE 118 constant.
6.
Target Corrected Resistance is another tool which further refines the
pass/fail criteria. If checked, the MTA software will fail a motor if the
readings are not within the tolerances. For the example motor its
resistance reading, using a DVM, is 3.1 ohms. So it would be possible
44
Doc #: 71-009-001 Rev 1
to check the Target Corrected Resistance check box and enter the
value of 3.1 +/- 10%. Enabling target corrected resistance makes this
Test ID specific to the example motor. If resistance data is not
available, do not enable this.
7.
Click on the Close button.
Configure Megohm/PI/HiPot Tests
1.
To configure the Megohm/PI/HiPot tests, press Config/Acquire Data
button under the DC Tests heading to bring up the DC Tests screen. For
this motor, the Megohm and PI tests will be run at 500V while the HiPot
test will be run at 2000V. Consult IEEE 43/95 or another appropriate
standard to determine test voltages.
Fig 3-6: DC Test Parameters
2.
Since this is a small motor, the PI test will be ran as a DA test only by
selecting the DA Only from the middle combo box.
This motor has newer insulation doing a full PI test will not yield any useful
information.
The other option, DA If IR>5000 @1m, sets up MTA for Windows to
automatically skip the PI test in favor of the DA test, at 3 minutes if the
insulation resistance (IR) is greater than 5000 megohms at 1 minute. Insulation
45
Doc #: 71-009-001 Rev 1
resistance readings 5000 megohms or greater at 1minute is the generally
accepted criteria for aborting the PI test. Once the DC Tests are configured as
shown above, press the Close button to return to the main test screen.
Configure Surge Test
1.
Press the Config/Acquire Data buttonunder the Surge heading.
Fig 3-7: Surge Test Parameters
2.
Configure the surge test as shown. Select the Target Voltage to be 2000V
which is approximately 2*V + 1000.
3.
The L-L EAR (Lead-to-Lead EAR) has been turned off since this motor
will be tested with the rotor installed. If this option were left selected, a
nuisance trip would almost certainly occur as the rotor coupling is different
for each phase winding.
4.
The P-P EAR (Pulse-to-Pulse EAR) is set to 10%. This means a pulse-topulse EAR value greater than 10% will cause the MTA for Windows to flag
a failure.
5.
The Test-Ref EAR(%) is set to 10% which means that if a test is run, and a
reference test exists, the reference waveforms will be compared to the
acquired waveforms. Should the EAR values between reference waveforms
and acquired waveforms be greater than the value shown, the MTA for
Windows will fail the motor. If this option is not checked and is grayed out,
no reference waverform is associated with this test.
6.
Press the Close button in the upper right corner of the Surge Data
Acquisition screen to return to the Tests view.
7.
On the Tests view click on the Save button to save the Test ID to the
database. From this point on the Test ID called “Delco_460V/wPI” will be
46
Doc #: 71-009-001 Rev 1
used to test the Delco motor or any other motor that has this Test ID
assigned to it.
Generic Test ID’s versus Specific Test ID’s
The Test ID just created above is specific to the Delco 460 V motor of this
example. This Test ID should not be used for another 460 V motor such as a 100
hp/460 V motor. The reason is that we entered a Target Resistance value of
3.1Ω (ohms) which it is specific to this 3 hp Delco motor. If this Test ID were
used to test a 100 hp motor, the resistance test would fail because the 100 hp
motor will have a much lower winding resistance than 3.1Ω (ohms). Therefore,
if a Test ID is to be used for many motors, the Target Corrected Resistance
option should not be used. Without a Target Corrected Resistance, there is no
specific or unique information that ties the Test ID to a specific motor. Baker
has already provided several Test ID’s based on machine voltage in the
database. These are generic Test ID’s. (Target Corrected Resistance checking is
disabled.)
Running a Real-Time Test Sequence
Once a new Motor ID has been created, and a new Test ID for this motor has
been created, a real-time test can be run. The following sequence is
recommended:
1.
2.
3.
4.
5.
6.
Temperature
Resistance
Megohm
PI
HiPot
Surge
At the end of the sequence, you will need to click on the yellow Save Results
button to save all test results in the same record. You may save after each
individual test, however each test results will be save in a different record.
Example Test ID:
Temperature Enabled
Resistance Enabled – Max Delta %
Megohm Enabled – Test Voltage 500, Min Meg 10, Time 60s
PI Enabled – Test Voltage 500, Min Meg 10, Time 600
HiPot Enabled – Test Voltage 2000, Min Meg 10, Time 60s
Surge Enabled – Test Voltage 2000, P-P EAR, 10%

Acquire Megohm/PI/HiPot: Click Config/Acquire Data button for DC Tests.
Fig 3-9: Acquire Megohm/PI/HiPot Data
49
Doc #: 71-009-001 Rev 1
The DC tests can be treated as one continuous test. Starting with the Megohm
test using a low voltage held typical for 1 minute. Next is the Polarization Index
(PI) test held at the same voltage as Megohm for 10 minutes the first minute
being the Megohm test. Or the Dielectric Absorption (DA) test which is a 3
minute PI giving a ratio of the 30 second reading to the 3 minute, instead of the
1 minute reading to the 10 minute reading. The final test is the HiPot in which
the voltage is increased to a higher target voltage and held for 1 minute. Consult
IEEE 43 and IEEE 95 for the appropriate test voltages.
1.
Set the knobs as instructed in your Digital Tester’s manual.
2.
Click the Run Selected Tests button. The software will instruct you to
push the Test button on the digital tester. Push the test button on the
tester. You have 4-5 seconds to push the test button on the tester before
it times out.
3.
Slowly increase the voltage output on the tester. The voltage and
current will be displayed as blue and red bars on the screen of the
computer. If these bars do not appear after 5-6 seconds, release the
Test button and repeat the step above. Note there is a slight delay in
response due to the communication between the tester and computer.
4.
Increase voltage to the test voltage specified by the Test ID; a target
voltage line appears on the voltage slider bar. When you reach the
target voltage a message in yellow will appear.
5.
Adjust µ-Amps/div knob on the tester to best match the leakage current
of the motor being tested.
6.
Hold the Test button on the tester for the amount of time entered in the
Test ID for the Megohm test. One minute is the standard time for a
megohm test. A timer on the computer screen will count down the
remaining time.
7.
At the end of the Megohm test continue to hold down the Test button
on the tester. A DA test was requested to be performed, at the end of
one minute the time remaining will reset to 2 minutes remaining for the
DA test. (Since 1 minute has passed for the megohm and DA is 3
minutes in total) After a few seconds the DA/PI dialog will be
displayed, plotting megohm values at each minute and current values at
each second.
50
Doc #: 71-009-001 Rev 1
8.
Once the DA test has concluded, you will be prompted to increase the
voltage to the HiPot target voltage. Before increasing the voltage,
change the µ-Amps/div knob to the 100 µ-Amps/div to avoid an over
current trip. Increase the voltage to the Test ID’s test voltage for HiPot,
for this example that is 2000 volts. A message will be display when
you hit the target voltage.
9.
At target voltage re-adjust the µ-Amps/div to best match the leakage
current.
10. Remain holding the test button as the computers time remaining counts
down the specified time. Consult IEEE 43 and IEEE 95 for
recommended HiPot test times.
11. At the end of the test you will be prompted to release the PTT button on
the tester. A few seconds after the PTT button has been released; the
computer will be ready to respond to commands. During this time the
computer is still communicating with the tester. You will get a
message on the CRT screen of the tester that indicates an error in the
transmission has occurred. This is normal.
12. If satisfied with the test results press the Close button and return to the
Tests View.
13. Continue to the Surge Test
Note: Keep your main attention on the Digital tester. Occasionally glance at
the computer’s screen to insure that the data logging process in proceeding
properly and to check test time remaining. The clock displayed on the CRT
screen of the tester will not be accurate while communicating with the computer.

Acquire Real-Time Surge: Click Config/Acquire Data button for Surge
Tests.
Fig 3-10: Acquire Real Time Surge
Real time surge will acquire data from the tester to the computer after each surge
pulse is applied to the motor under test. As a waveform is acquired, it will be
displayed as nested waveforms. The waveforms at 1/3-Target voltage, 2/3Target Voltage and Full Target Voltage will be saved as the test for each lead
progress. If the pulse-to-pulse EAR is turned on, as the voltage reaches 1000
volts a smaller graph will appear in the lower right corner of the surge graph
displaying the pulse-to-pulse EAR values from one pulse to another. If a turnto-turn short is detected the software will flag a failure and you will need to
release the test button on the tester.
1.
Set knobs and selector switch to Lead 1 as described in the Test’s
manual.
52
Doc #: 71-009-001 Rev 1
2.
Click Surge Lead 1 button. A green Ready Lead 1 message will be
displayed.
3.
Quickly press tester’s Test button. You will have about 10 seconds
between pressing the Surge Lead button and pressing the Test button on
the Digital tester. When the computer begins acquiring data a red
Testing Lead 1 message will replace the green Ready Lead 1
message.
4.
Slowly increase the output voltage until the desired test voltage is
reached. While increasing the voltage, watch the surge waveform
display, looking for indications of a turn-to-turn short. See the Digital
Tester’s manual for information on identifying turn-to-turn shorts.
5.
Release the PTT button when the Target Voltage is reached or a failure
is detected. A message will be displayed on the computer screen in
either case.
6.
The Surge Data Acquisition Dialog will show the final display of the
waveforms.
7.
If the Seconds/div knob or Volts/div knob need to be changed to fully
display the surge wave, make any adjustments then repeat procedure
above for capturing data.
8.
Repeat the same procedures for Leads 2 and 3. After all three leads
have been tested; the lead-to-lead Error Area Ratio (EAR) values will
be calculated and displayed on the right side of the surge window. The
peak voltage from each lead’s test will also be displayed.
9.
If the test results are satisfactory, press the Close button to return to the
Tests view.
Note: The Surge All Leads button will automatically sequence through Lead 1,
Lead 2 and Lead 3 as if each button was pressed individually. The operator will
only have to operate the tester.

Saving Data
Fig 3-11: Saving Data
Once all tests has been completed return to the Tests view. All tests that have
data acquired will display one of the following flags:
• Green Pass flag, if the test passed all parameters
• Red failure flag and reason why failed, if the test failed at least one of
the parameters
• Cyan Tested flag, if the data was acquired but it could not be
determined that it pass/failed or did not have any parameters set.
The Save Results button will be highlighted. Click it, when finish with the
sequence of tests.
Note: Test results must be saved prior to viewing them in the Data tab views
such as, Results Summary, Surge or PI.
Reviewing Test Results/Data
After the test results have been saved to the database, they can be reviewed
using the Data tab on the right hand pane of the MTA for Windows main
window. The Results Summary tab shows a Date/Time window on the top part
of the screen and a spreadsheet style view of the data on the bottom.
54
Doc #: 71-009-001 Rev 1
The Date/Time Window shows a quick summary of the time and date of tests
and whether the tests passed or failed. Double click on a test date and time to
move to a new record.
Fig 3-12: Date/Time Results Summary
The spreadsheet style of
results view shows the actual
test data as acquired. The test
date and time is shown across
the top of the window and the
specific measurement results
are shown in each column.
The PI test can be reviewed by
pressing the PI tab. PI view
will display the PI/DA graph
along with a table of the
current and megohm readings
gathered at specific times. The
PI voltage, DA ratio and PI
ratio are displayed on the right
side.

Printing Reports
MTA for Windows comes with a complete set of report generation features to
facilitate the requirement that test results be made available to managers,
owners, and repair personnel. Reports containing test data, nameplate data,
application data, etc., can be printed to a physical printer or can be “printed” to a
Microsoft Word 2000/XP/2003 file.
The following are three ways to invoke the Report Generator, shown above,
clicking on the File – Print menu item, holding down the control key and
pressing the “P” key, or pressing the printer icon on the upper left of the main
screen. The top section of the Report Generator, called Select Filter(s), contains
the filters by which you can choose what test results to print. You can select the
current motor and test result, or use any combination of the other filters, such as,
a date range and all motors that fail any test during that given test range. The
bottom section of the Report Generator dialog is called Select Reports. This
section is where you choose what reports you wish to print.
57
Doc #: 71-009-001 Rev 1
Fig3-16 Report Generator
The Report Generator can look a bit intimidating, especially when you only
want to print out the test result you have just been reviewing.
This is the simplest case. The motor and test result that is selected in the main
program will appear to the right of the checkbox titled Current Motor/Test
Fig 3-17: Print Filter
Results as seen in Fig 5-18. Click on that box and select which report is to be
printed in the lower part of the window and press the Print button. You will be
asked which printer to use and the selected report will be sent to that printer. In
Fig 5-19 the Results Summary with Surge Summary has been selected.
58
Doc #: 71-009-001 Rev 1
Fig 3-18: Print Select Reports
If several motors’ data need to be printed, instead of selecting one motor’s test
results, then selecting the next motor and the appropriate record to be printed,
and repeating this for all necessary reports, one at a time, the software provides a
more elegant solution. The Report Generator can select all records that match a
certain criteria. Those items used to filter the data are the Motor’s location
fields, date range, or pass/fail criteria. Different combinations of the above
options can be used, such as any motor at a given location within a given date
range that failed a Surge test can be printed.
Once you have determined what test results to select, there are several choices
for what reports to print. Nameplate, Application, Summary, Surge, or PI Test
reports can be chosen. Use the Selection Filter (top part of the dialog) along with
the Selected Reports section (bottom part of the dialog) to create reports. For
instance, if you have the filters set to select all test records that failed the PI, but
you print only one of the surge reports, you will probably not get the
information you are need. It is important to think out what you are selecting on
and what you want to see. You can easily set up the filters to select many test
results, but this may not be what you want or have time to print.
Consider the situation where an electrician tests many different motors during
the day and needs to print reports for those motors that failed before going
home. In this case the Report Generator should be configured as shown in Fig 520. The Select Filter(s) section of the window has the Date Range selected and
set both dates as 4/29/2005. This will cause the application to look for all test
results that took place on 4/29/2005. Next filter selected is the Pass/Fail. Select
the FAIL radio button. This will cause the application to print results for
motors that have failed one or more tests on this date. Tests that passed will not
be printed. In the bottom Select Reports section, the Results Summary with
Surge Summary is selected. When the Print button is pressed, the Report
59
Doc #: 71-009-001 Rev 1
Generator will go thru the entire database, looking for any failed tests that
occurred on 4/29/2005. Once it is done searching a dialog box will appear
informing you of how many records were selected. You can either choose to
cancel or continue and print the selected reports.
Fig 3-19: Report Generation Example
Note: The Report Generator can be set up so that a large number of reports are
created. Printing out a large number of reports can be very time consuming,
especially when going to Microsoft Word . The Report Generator will inform
you of how many test results are chosen, this is not the number of pages that will
be printed. That depends on the number of reports chosen.
The program can also print reports to Microsoft Word, (see Fig 5-21) if it is
installed on the desktop computer running the software. This feature provides a
way to annotate reports by adding text to the Word Document as required. For
example, a comment regarding the vibration level of the motor before it was
turned off can be added to the Word document. This feature should also be used
with caution because printing reports to MS Word takes some time – selecting a
60
Doc #: 71-009-001 Rev 1
lot of records to print means the system will be tied up for a long period of time
before all records can be transferred to the Word document.
A typical Word report looks like the figure below. Each of the sections is a
Word table, except the surge waveform which is a bitmap. The reports can be
modified by adding text between the tables or the data tables can be cut and
pasted into other documents. See the next three pages for a sample report.

Database Management
Database management is a highly important feature of a good predictive
maintenance-testing program. It facilitates organization of periodic maintenance
data. The database section of the MTA for Windows software allows the entry
of identifications to help clarify the location of specific motors, along with the
use of multiple databases to help organize overall program maintenance. You
will need to develop a best practice in keeping the data collected, easily
accessible and meaningful. The discussion in this chapter will be about the tools
the Analyzer Software provides to aid you in database management. The
following will be discussed:
• Motor ID
• Motor Location Fields
• Multiple Databases
• Data Transfer
• Archive
• Restore
• Conversion of Older Databases
Consequences of Not Organizing Data
It is recommended to establish a structure that is to be used by all persons
performing tests. Consider the following example: A maintenance program is
established to test motors at seven plastics production plants, each in a remote
location. Each plant has nearly 1000 motors that are identified as needing
periodic testing. All works well for several months until a motor that was
previously tested fails. The maintenance manager wants to see all the test data.
When the project supervisor looks at the data, he finds nearly 7000 tests, all in
one large database, and in a random order. He spends about an hour looking for
the last test performed and gives up. Upon investigation he finds that each of the
technicians using the equipment has been entering the data based upon what
made sense to him at the time. Because of the disorganization, important test
data has been lost or at best difficult to locate.
The database structure is designed to facilitate data organization and to be
flexible enough to allow you to uniquely plan for your needs. The Motor ID,
two location fields, and the multi-database abilities are the tools for you to use to
organize the data so that the above scenario does not happen to you.
67
Doc #: 71-009-001 Rev 1
Motor ID Field
The records that are stored are linked to each other hierarchically. The principle
field, which serves as the base for linking associated records, is the Motor ID.
The Motor ID is also the main means of locating and interacting with a motor’s
data. Therefore it is important to develop a naming scheme that will facilitate
location and retrieval of information. Case in point, it is not uncommon for a
plant to have duplicate processes, with identically named motors in each process
(ex: Intake Pump) . This can cause confusion, since the motors have the same
Motor ID, but are in different locations. Take steps at the start to ensure that the
Motor ID’s will be unique!
Example: If Intake Pump is present in duplicate processes, it makes database
management easier if these two motors can be uniquely identified. One way to
solve this problem is to include in the Motor ID the process ID as in the
following: The Motor ID for Process 1 could be “Intake Pump P1” while the
Motor ID for Process 2 could be ‘Intake Pump P2”.
Motor Location Fields
The Motor ID is the primary identifier
of a motor by which it can be located.
There are two other fields that are used
to help in locating a motor in the
database. The location fields have
default field names of Location and
Building. If these labels do not make
sense for your situation then you can
change them. (Choose View-OptionsChangeable Labels menu item from
the AWA software.) For instance, for a
plant maintenance program with several
plants, the label of the location fields
may be renamed to Plant and Unit.
These location fields along with the
Motor ID are entered as part of the
nameplate record and are used to make
up the tree structure of the Explore tab.
In the example Explore tab to the right,
motors have been organized by location
Fig 4-1: MTA Database Tree
68
Doc #: 71-009-001 Rev 1
in Plants and Units. North Platt and South Branch are Plants and Unit 23,
Unit45A, Unit 17C are all units.
Multiple Databases
The MTA for Windows software allows the use of multiple databases. You may
split the data between different databases, grouping motors in whatever way that
is beneficial to you. For example, motor shops might want to use different
databases for each of their customers. A preventive maintenance department
could use a different database for each part of their plant. You may need to keep
the data in a centrally located database on a network and have databases locally
on other computers, which are used to update the main database.
It is important to establish your best practices for database organization early
and maintain adherence to the establish practices to avoid loss of data or data
from the same motor being in several different places.
Note: Manipulation of the database may be useful for management and auditing
purposes. Do not delete records associated with Motor IDs. Proceed with
caution when manipulating data always backup a database before deleting
records or manipulating the database in any way.
Opening a Database
To open a database, select the Open option under the File menu or click on the
on the toolbar. An open file dialog box will pop up and
open database icon
allow the selection of a database to use as shown below. It will default to the
Fig 6-2: Select Database
69
Doc #: 71-009-001 Rev 1
folder that has been selected in View-Option-File Locations menu item. In the
case above the default folder is MTAData. By selecting a database (.mdb) and
clicking the Open button or by double clicking the desired database the AWA
application will open the database.
Creating a New Database
To create a new database, select the New from the File menu item or the new
on the toolbar. The Create New Database dialog will be
database icon
displayed, as seen below. The Save in folder is the default folder, you can
Fig 6-3: Create New Database
navigate to another folder if desire, enter the name of the new database in the
box next to the File Name: and click on the Save button. A database will be
created and opened that has one default motor and the Baker default Test ID’s.
At this point you can begin entering new motors using the Data-Nameplate tab.
Data Transfer
The Data Transfer tool allows you to transfer motor and test information from
one database (source) to a second database (destination). The transferred
information is not deleted from the source database, it is only copied to the
destination database. The Data Transfer can be used to combine two existing
databases into one centrally located database. It can also be used to re-organize
70
Doc #: 71-009-001 Rev 1
exiting database into more convenient groupings. Anytime you need to move
motor data or Test ID’s the Data Transfer provides this functionality.
Transferring Motor and Test Result Data
In order to transfer motor information, test result data and Test ID’s, two
databases need to be open. A source database, the database to transfer
information from, and a destination database, the database to transfer
information to. Both databases must exist before beginning the transfer. To
transfer to a new destination database, create it before beginning the Data
Transfer, by selecting File-New menu item or clicking on the new button on the
toolbar.
There are two ways in which to start the Data Transfer. The first method is to
choose the Database-Data Transfer menu item from the software menu, or
click on the Data Transfer button on the toolbar.
or
Fig 4-1: Data Transfer Buttons
Once the Data Transfer is started it
will present an open source file
dialog box and default to the folder
in which the currently open
database resides. For example, in
the above screen shot the
Example3 database is open in the
main program. When the Data
Transfer button is clicked, the open
source file dialog defaults to the
MTAData folder with the
Example.mdb for the File name.
Fig4-2: Select Source AWA Database
71
Doc #: 71-009-001 Rev 1
The option to pick the default database or choose another database to transfer
data from is available.. This is the source database.
Once the source database is chosen, click the Open button. The following dialog
will be displayed, with the source database opened on the left side. Notice the
familiar Motor ID tree structure.
Fig 4-3: Data Transfer Select Screen
After the Data Transfer dialog is displayed, click on the destination database
Browse button, in order to open the destination database.
72
Doc #: 71-009-001 Rev 1
Presented will be a destination file open dialog. It will default to the same folder
as was used to open the source database. Choose a destination database to open
and press the Open button. At this point the software returns to the Data
Transfer dialog with both databases open.
If either database is not the desired database, choose the appropriate databases
by clicking on the Browse button next to the wrong database and choose
another.
Fig 5-4: Data Transfer Destination Database
Fig 4-4: Data Transfer Destination Database
When both the source and destination databases are open the Add All and the
Add buttons are enabled. The application is ready to select motors from the
source database to be added to the Transfer List. The Transfer List is the list
of motors that will be transferred when the Transfer button is pushed. The Add
All button adds all the motors in the source database to the Transfer List. The
following gives two ways to add selected motors to the list.
1)
Highlight the motor to add, and press the Add button.
73
Doc #: 71-009-001 Rev 1
2)
Double click on the motor to add.
If there are motors on the Transfer List that are not to be transferred, remove
them by selecting a motor(s) and pressing the Remove button. When the
Transfer List is finalized, press the Transfer button.
The method the Data Transfer application uses to transfer the data is as follows.
The Data Transfer runs through the Transfer List adding the motor
(Nameplate) information if the motor does not exist in the destination database.
If the motor does exist, no motor information will be added. Next, the Data
Transfer adds any test records that do not exist in the destination database. It
compares the time/date stamp with existing test result records and if the source
time/date equals a test result record in the destination database it does not
transfer the record. If the application does not find any matching time/date then
it adds the source test result record to the destination database.
The Data Transfer creates a log during the transfer process. Information logged
is source/destination database names, Motors ID’s added, and number of records
updated. If the transfer encountered any problems, it also logs the Motors ID
and reason the transfer failed. Print this log by clicking on the Print Log
button.
Transferring Test ID’s
NOTE: Test ID’s are transferred separately from the Motor ID’s.
To transfer Test ID’s follow the method described in the “Transferring Motor
and Test Result Data” section on how to open a source and destination database.
The source and destination database both must be open before any transfer can
be performed. Once both databases are open, the Transfer Test ID’s button
will be enabled. Press this button to display the dialog below.
The dialog displays all Test ID’s in the source database, as well as the Test ID’s
of the destination database. Choose the Test ID’s to transfer by highlighting the
source Test ID’s to transfer. Use the shift and control keys while clicking on
the Test ID’s to select more than one. With the desired Test ID’s highlighted,
press
74
Doc #: 71-009-001 Rev 1
Fig 4-5: Transfer Test ID's
the Transfer button to start the transfer. The Data Transfer will transfer (copy)
the requested Test ID’s to the destination database. If the Test ID exists in the
destination database then it will not transfer the Test ID and will display a
message about not be able to duplicate Test ID’s. If this message is displayed,
click on the OK button and the transfer will continue. As in the motor and test
result record transfer, the application writes to the Transfer Log as to what
action has been taken. Once finished transferring Test ID’s, press the Close
button to return to the main Data Transfer dialog.
Archiving a Database
Along with the Data Transfer, Archiving (compact/zip) is a tool to help move
data. This functionality exists for backup and shuffling of whole databases
from one computer to another as oppose to the Data Transfer which moves
motors/test information from one database to another database. It is important
to retain a current backup copy of database(s) on some persistent storage
medium, such as floppy diskette, CD, or a backed up network drive. The
Archive provides an easy means to backup data. Use the Archive option for
more than just a backup. It is the best way to put a database on a floppy drive to
move it from one computer to another. If the Archive option is used to copy and
compress a database to a floppy, use the Restore option, discussed the next
chapter, to extract the database from the floppy back to the hard drive.
75
Doc #: 71-009-001 Rev 1
In order to use the Archive feature, WinZip must be installed on your system.
(Supplied with MTA or available from www.winzip.com.) The WinZip
application compresses files, so significantly less room is required for storage.
This makes the files more convenient to store (archive), transfer to a floppy, or
e-mail. The Archive automates calling WinZip and compacting the database.
To archive a database, it must be opened in the MTA for Windows application:
1) Choose the Database – Archive menu item.
Fig 4-6: Archive
2) The application will display a New Archive dialog box, in the default
folder, with a default zip file name. The Look in folder defaults to the
path that has been entered in the View – Options – File Locations
menu item. Either accept the default or browse to the folder where the
archived file is to reside.
Fig 4-7: New Archive
76
Doc #: 71-009-001 Rev 1
Note: If the default is the floppy drive make sure there is a diskette in the drive
before archiving.
The default name of the archived (zip) file will be a combination of the database
name and the time/date of the archive. For example, if the database name is
Example.mdb then the archived file name will be:
Example_YYYYMMDDHHMMSS.zip. The YYYYMMDDHHMMSS
indicates the year/month/day/hour/minute/second when the file was archived.
If archiving to a floppy drive such as “A:\” and the file is too big to fit on one
floppy disk create a multi-disk archive by inserting another disk.
When the archiving is in progress the WinZip dialog & status bar is displayed.
Once finished the following message box will be displayed.
Fig 4-8: Archive Complete
It is important to note the location of the archived file (.zip). Press the OK
button to return to the application.
Restoring a Database
In order to view archived data with the MTA software the database must be
restored first. To restore an archived database WinZip is needed. (See
Archiving a Database.)
Fig 4-9: Restore
77
Doc #: 71-009-001 Rev 1
1) Choose the Database – Restore menu option.
2) The Select Archived Database dialog box will be displayed. Choose
the database (.zip file) to be restored and open it.
Fig 4-10: Select Archived Database
3) After choosing the archived database to restore, selection of the folder to
extract the archived database into is needed. If the database is to be restored to
a different folder, browse to that
folder. When the appropriate
folder is located click on the OK
button.
Fig 4-11: Browse for Folder
78
Doc #: 71-009-001 Rev 1
The application will invoke WinZip to extract the archived file. If a database
with the same name exists the following will appear.
Fig 4-12: Confirm File Overwrite
To overwrite an existing database, choose Yes to All. To overwrite the existing
database, choose Cancel. To restore the archived database, to either rename the
existing database through Windows Explorer then restore again or restore using
another folder that does not contain the same named database.
Once WinZip is finished extracting the database the software will be return to
the MTA application’s main screen. Choose File – Open menu item to open the
newly restored database.
Converting an Older Database
Version 3 of the MTA for Windows software uses a different database structure
than prior versions. The test results data are arranged differently, the database
keys are different, and several tables have been combined or added, in addition
to many other improvements. One of the major changes is that the surge data is
no longer stored in a separate set of files in a “Srg” folder – all surge waveform
data is now stored in the database.
Note: Care needs to be taken when upgrading to this new version of the
database. After installation of the new software, the old databases on your
computer will still be present. It is left to the user to insure a smooth transition to
the new database and software. Here are a few suggestions for making the
change to the Version 3+ database:
79
Doc #: 71-009-001 Rev 1
1.
Make a backup copy of all old databases. Use WinZip, an older stand alone
version of the Data Transfer archive feature, or simply use Windows
Explorer to make a copy.
2.
Install the MTA for Windows 3+ software.
3.
Convert all of the old databases to the new version by opening each of the
old databases with the MTA version 3+ software, as described later.
4.
Verify data has been correctly converted in the new databases. The old
databases will still be on the machine.
5.
Once confident the data is correct, remove the old databases from the
computer, to avoid confusion as to what version to use. The old data is
typically stored in the C:\MTAData\YourDatabaseName\. To delete the old
databases, after conversion, delete each database’s individual folder. The
version 3.0+ database is stored in the C:\MTAData\ and not in individual
folders. For example: old database is called MyBakerDb.mdb, is located in
C:\MTAData\MyBakerDb\MyBakerDb.mdb. It will also have a srg folder.
After conversation it will be located in
C:\MTAData\MyBakerDb_Rev3.mdb with no srg folder if all defaults are
taken. Note: If defaults are not used, attention need to be paid to what the
names are and where the databases were saved.
If data resides on a network or desktop(s), make sure that all databases, not just
those stored on the computer, have been upgraded. This will insure the old
databases do not get advertently used for new testing.
Converting the Data
Version 3+ software stores database files in a different place than prior versions:
Database files are now in C:\MTAData without an additional database folder.
Older versions stored database files in subfolders within C:\MTAData. Of
course these locations are the default locations programmed into the software;
databases can be stored anywhere on the machine’s disk or even a network.
80
Doc #: 71-009-001 Rev 1
When using the Version 3+ software for the first time, the databases from
previous versions will have to be converted. The conversion process happens
Fig 4-13: Convert Database
automatically when the application opens an older database. In order to open an
older database, the File-Open dialog will have to be used to pick the old
database from the C:\MTAData\Your Database Name\ folder where they are
stored. The software will automatically identify the database as an old database
and presents the operator with the following message indicating the database
will be converted.
The Version 3+ software will then present a Convert Database Into save dialog
box with a new database name filled in: the new name is the old one with a
_Rev3 appended to it. The database name can be changed to whatever is
desired, however, it is recommended that a consistent naming convention and an
unambiguous location be used.
Once a File name is entered press the Save button. The conversion will begin
immediately. All Test ID’s, Motor ID’s and Test result data will be converted.
When the conversion is concluded the application will open the converted
database.

The following instructions are a guide to replacing the EPROM chip that
contains the Digital Tester’s firmware.
Step 1.
Place the Digital Tester on a clean workbench and remove the power plug to the
unit.
Step 2.
Remove the black screws on the Display Control board and Function board. Use
a M2.5 hex key or ball driver. Set the screws aside.

Step 3.
Grasping the knobs pull out the Function Select board. Pull the board straight
out. Over 10lbs of force may need to be applied to remove the board from its
internal connector.
Step 4.
Grasping the knobs remove the Display Control board. Again, over 10lbs of
force may be needed to pull out the board from its internal connector. Also, pull
this board straight out.

Step 5.
The remaining circuit board in the tester’s card cage is the controller board.
Grasping the end of the board pull this board straight out and place it on the antistatic foam provided.
Step 6.
Using a chip puller remove the PROM (U3) from its IC socket. A pair of pliers
can be used in a pinch as shown in the photograph. A small screwdriver may
also be used to pry the chip out of the IC socket. Take care not to bend the leads
of the chip. After the chip is removed, insert the chip into the anti-static foam
provided.

Step 7.
Remove the supplied PROM from the anti-static foam and install it in the
PROM’s IC socket. Take great care to not bend the leads of the new PROM
while inserting the chip in the socket. Make sure the chip is fully seated in the
IC socket. Also make sure the small “divot” on one end of the IC is aligned with
the decal of the chip that is printed on the PC board.

Step 8.
Insert the controller board in the Tester’s card cage. The top and bottom of the
controller board will ride in small plastic channels in the card cage. The IC’s are
on the right side of the board as the board is re-inserted, otherwise the board is
in upside down. Gently insert the connector of the board in the mating connector
inside the card cage. Be very gentle at this point. Less than a pound or two of
force is required. Gently wiggle the controller board back and forth until the
connectors mate. Once the connectors are aligned, push with about 5lbs of force
to insure that the controller board is completely seated in the card cage. If the
connectors do not mate, remove the controller board and inspect the pins on the
board’s connector. Check for pins that have been bent over. Bent pins can be
straightened with needle nose pliers. Re-insert the controller board in the card
cage taking care to get the boards in the plastic channels of the card cage.
Step 9.
Re-insert the Display Control board in the slot to the left of the controller board.
Once again, insure the card is riding in the plastic channels in the top and bottom
of the card cage. Follow the same procedure above. Gently wiggle the card until
the connector’s line up. Push the card in firmly to fully seat the connector.
Step 10.
Re-insert the Function Select board using the same procedures above.
Step 11.

Connect the power cord and turn on the tester. Test the Digital Tester with a
motor and verify that all functions of surge testing and HiPot testing are working
properly.
If problems are encountered, remove and reseat the boards again. Make sure the
Display Control board is on the left and the Function Select board is on the right.
Feel free to call the Standard Products Service Department at Baker Instrument
Company for help.
Step 12.
Replace the black socket head cap screws removed in Step 2.
