Performing an Insulation Resistance Test

The five insulation resistance tests take measurements on mains (L1 & L2) to Protective earth, applied parts to Protective earth, mains to applied parts, mains to non- earthed accessible conductive points, and applied parts to non-earthed accessible conductive points.

To access the Insulation Resistance Test menu, press M.

All Insulation Resistance Tests can be performed using 500 or 250 volts dc. To change the test voltage from the Insulation Resistance Test menu, press the softkey labeled More. Pressing the softkey labeled Change Voltage will cause the test voltage to toggle between 250 and 500 volts dc.

Note

Exiting and re-entering the Insulation Resistance Test menu causes the test voltage to return to its default value of 500 volts dc.

As shown in Figure 11, three of the five tests are shown over function soft keys F1 through F3. To access the other two tests or test voltage selection, press the softkey labeled More. The softkey labeled Back will move the menu back up to the top-level insulation resistance test menu.

After selecting one of the tests by pressing the appropriate softkey, press Tto apply the selected voltage to the DUT and take the resistance measurement.

Figures 12 through 16 shows the electrical connections between the Analyzer and DUT for the five insulation resistance tests.

Note

The DUT is powered off for this test.
