Figure 5.7: Examples of Earth continuity resistance measurement results
Displayed results:
Main result ............. Earth continuity resistance
Note:
Consider displayed warnings before starting measurement!
It is recommended that the mains cable is folded during the test.
is displayed when result is corrected with compensated lead resistance value.
Earth continuity result correction is disabled, when testing IEC cords between PE of
the IEC test terminal and PE of the test socket.
If the PRCD test is set in the Autotest procedure power is applied to the mains test
socket during the earth continuity test. This feature enables to test special types of
RCDs (PRCD-K, PRCD-S) where the PE conductor is not connected until power is
applied to the device.
5.2.3. Insulation resistance
The insulation resistance test checks the resistance between live conductors and earthed
(or isolated) accessible metal parts of a device under test. This test can disclose faults
caused by pollution, moisture, deterioration of the insulation material etc.
The instrument measures the insulation resistance between:
The (L+N) on test socket and PE terminal on test socket / (S/EB) terminal;
LN terminal and PE terminal / (S/EB) terminal (for fixed installed appliances).
This function is primarily intended for testing Class I appliances.
