To edit parameters, press the F1 function key first. Use
¿
and
À
cursor keys to select
the parameter you want to edit. By using
½
and
¾
cursor keys adjust the selected
parameter. Press F1 function key again to confirm settings.
Once the settings have been set, press the START key to perform measurement.
The measurement can be aborted by pressing STOP key at any time. The actual result
is shown on the display during measurement. After the measurement time period has
elapsed the last measured value is displayed, and PASS or FAIL indication appears on
the display (based on the high resistance limit defined in the settings).

6.2 Insulation
resistance
The insulation resistance test checks the resistance between live conductors and
earthed (or isolated) accessible metal parts of an appliance. This test can disclose faults
caused by pollution, moisture, deterioration of insulation metal etc. The capacitive part
of leakage currents is not measured because of the DC test voltage.
6.2.1 Insulation resistance on class I appliances
The instrument measures the insulation resistance between:
Ì
(L+N) and PE of the relevant test socket,
Ì
LN and PE test sockets.
