Insulation Resistance Test

The five Insulation Resistance Tests measure mains
(L1 and L2) to Protective earth, applied parts to Protective
earth, mains to applied parts, mains to non-earthed
conductive points, and applied parts to non-earthed
conductive points.
To access the Insulation Resistance Test menu,
push .
All Insulation Resistance Tests can be done with 500 V dc
or 250 V dc. To change the test voltage from the Insulation
Resistance Test menu, push the More softkey. Push the
Change Voltage softkey to toggle the test voltage
between 250 V dc and 500 V dc.
When you exit and re-enter the Insulation
Resistance Test menu, the test voltage is set to
its default value of 500 V dc.
As shown in Figure 8, three of the five tests are shown
above function softkeys F1 through F3. To access the
other two tests or test voltage selection, push the More
softkey. The Back softkey will move the menu up to the
top-level Insulation Resistance test menu.

Note
Figure 8. Insulation Resistance Measurement
After you push a test softkey, push  to apply the test
voltage to the DUT and take the resistance measurement.
Figures 9 through 13 show the electrical connections
between the Product and DUT for the five Insulation
Resistance tests.
The DUT is powered off for this test.
