5. After the test parameters have been modified as needed, click the Close button to return to the Main window,

ready to test a known-good motor to obtain your Surge test reference.

Testing a Reference Motor

1. To obtain the reference test, ensure that the Edit Test ID box in the Tests tab is checked. Immediately after
setting up the test parameters, connect the reference motor to the tester and confirm that the Motor ID
displayed on the toolbar is the reference Motor ID.
2. If you want to ensure that the motor passes all tests, click the Run Auto Test button then resume the Surge Test
reference waveform process when you get to the Surge Test window. Otherwise, you can click on the Surge test
run button in the Tests tab and proceed.
3. In automatic mode, the test will commence on its own. For other modes, click on the All Lead button to start
the test. The analyzer will raise the test voltage to the define level and conduct all defined measurements for
each test lead. For a known-good motor, all tests should pass. When the tests complete, the tester will return
you to the Tests tab (in automatic mode; other modes, click Close to return to the Tests tab).
4. A message dialog appears to confirm that you want to save the test result as a reference.
5. If the results are good, click Yes. If the test needs to be run again, click No. Multiple tests can be run to obtain
the desired reference. In automatic mode, test results are always saved. The reference will become part of the
Test ID only when Yes is clicked in the Use as Reference dialog box.
6. Motors that use the Test ID associated with the reference motor's Test ID will now have Test-Ref EAR% enabled
in the Surge Test setup window.
7. When you have finished the process, click Save then uncheck the Edit Test ID box to turn off edit mode.
