10.7 Insulation Resistance Measurement@ 250Vdc
Always check for voltage
before testing and measuring
on a circuit. This instrument is
intended for measuring Low
n
and Insulation resistance on
un-energized circuits only.
Use the procedure explained
at points 7.2, 7.3, 7.4.
Check the test leads and fuse

resistance by zeroing the test leads and fuse as per
the 7.6 procedure.
Connect the test leads to the circuit to be measured
and wait for a few seconds. The instrument will
automatically discharge any remaining energy which
could be present on the circuit, and will check for
voltage at the same time.
Once you are sure that the circuit to be tested is not
energized, then press the button for a short test
duration or press and turn the button for a long test.
Once you end the test, allow a few seconds for the
Instrument to automatically discharge the circuit.
