Measurements
4.1 Measurement of insulation resistance
WARNING:
The tested object must not be live.
Attention:
During measurement, especially of high resistances, make sure that test leads
do not touch each other and probes (crocodile clips), because such a contact
may cause the flow of surface currents resulting in additional error in measure-
ment results.
