Not all Baker AWA-IV testers have low-voltage test leads. If this option is not
available, this screen will be slightly different; however, the test operation is
the same.
TEST SEQUENCE
The following sequence of tests will run automatically. If a test fails, the software will stop the
testing process, leads will be discharged and grounded, and you will be presented with choices for
continuing testing if applicable.
Under most circumstances, you should troubleshoot, diagnose, and repair the motor before going
on to the next test in the sequence.
Temperature entry
The Temperature/Resistance dialog will be displayed ready for the temperature reading to be
entered from a third-party temperature device.
1. Enter the temperature of the motor and click the
Accept
button to acknowledge the
temperature being entered.
2. Click
Next
to proceed. The tester will automatically proceed with the remainder of the tests.
Resistance
This test looks for resistance imbalance between phases. If a large imbalance is found, inspect the
motor for causes of the discrepancy. By comparing the values to a reference standard, you can
evaluate the following quality and degradation issues:
Field testing —
Inspect connections in junction box and look for high resistance connections, and
improper or loose connections.
Quality/post failure
—
Look for number of turn per phase variation, diameter copper variation,
turn-to-turn shorts, or turn opens.
