Performing an Insulation Resistance Test
Note
A reading of
OR
is used to indicate “Over Range”, a
resistance reading which exceeds the maximum
resistance value measurable on the Analyzer.
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
.
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 12, 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.

Figure 12. Insulation Resistance Measurement
After selecting one of the tests by pressing the appropriate
softkey, press
to apply the selected voltage to the
DUT and take the resistance measurement.
Figures 13 through 17 shows the electrical connections
between the Analyzer and DUT for the five insulation
resistance tests.
Note
The DUT is powered off for this test.
