3 Measurements
3.1 Double-lead measurement of insulation resistance
WARNING:
The object tested must not be live.
Attention:
During measurement, especially of high resistances, make sure that test leads
do not touch each other and the probe (crocodile clips), because such a contact
may cause the flow of surface currents resulting in additional error in measu-
rement results.
Set the rotary switch of function
selection at one of
R
ISO
, choosing
measurement voltage. The meter
is in the voltage measurement
mode.
Times for calculating absorption coefficients are fixed at t
1
= 15s (30s for the coefficients Pi DAR), t
2
=
60s and t
3
= 600s.
Connect test leads according to the drawing.
