Configuring DC tests
1) DC tests include MegOhm, DA/PI, HiPot, Ramp Voltage, and Step Voltage tests.
2) To configure one or more of these tests, click on any of the test configuration buttons
to the right of the DC test buttons to open the DC Tests setup window.
3) For this motor, the MegOhm and DA tests will be run at 500 volts while the Step
Voltage test will be run at 2000 volts. Consult IEEE 43/95 or another appropriate
standard to determine test voltages.
4) Because this is a small motor, the PI test will run only as a DA test by checking the
DA Only box, as shown in the example below. Doing a full PI test would not likely
yield useful information.

If you click on the DA Only dropdown list, you will see another option called Revert DA.
Selecting this test option sets up the analyzer to automatically skip the PI test in favor of the
DA test at three minutes if the insulation resistance (IR) is greater than 5000 MegOhms at
the one-minute mark. Insulation resistance readings of 5000 MegOhms or greater at one
minute is the generally accepted criteria for aborting the PI test.
