Figure 0.41: Example of insulation resistance - P measurement results
Displayed results:
Main result ............. Insulation resistance (LN – P)
Notes:

The currents flowing through the PE terminal of the mains test socket will NOT be
considered.

Consider any warning on the display before starting the measurement!

Do not touch / disconnect the device under test during the measurement or before it
is fully discharged! The message »Disch...« will be displayed while the voltage on
the device is higher than 20 V!

Substitute leakage

10.1.15
Leakage currents between live conductors and accessible metal parts (housing, screws,
handles etc.) are checked with this test. Capacitive leakage paths are included in the result
too. The test measures the current flowing at a test voltage of 30 VAC and the result is
scaled to the value of a nominal mains supply voltage.
The instrument measures the insulation resistance between:

Main test socket (L+N) and PE / (S/EB1) test terminals
This function is primarily intended for testing Class I appliances.
