WARNING
Do not attempt to measure insulation resistance
on a live line. Pressing the MEASURE switch or
lifting up it with probe connecting on a live line
may cause damage to the instrument or object
being measured. Before measuring the
insulation resistance, power off the object to be
measured.
To avoid electric shocks do not touch the end of
probes. When measuring insulation resistance
dangerous DC voltage is generated in the
measurement terminals.
2.2 Insulation Resistance Measurement
To investigate conduction and the insulation
of the object, the instrument will measure
insulation resistance. In preparing to
measure, there is a need to select the voltage
to be applied to the object to be measured.
