Substitute leakage - P measurement procedure
Select the SUB. LEAKAGE-P function.
Set the test parameters.
Connect device under test to the instrument (see
Figure 5.21
and
Figure 5.22
).
Press the TEST key for measurement. To stop continuous measurement press
TEST key once again.
Store the result by pressing MEM key (optional).
Figure 5.23: Example of substitute leakage - P current measurement results
Displayed results:
Main result…………..Substitute leakage current (LN – P)
Notes:
Consider any displayed warning before starting measurement!
The currents flowing through the PE terminal or PE of the test socket will not be
considered.
5.2.7 Polarity test
This test checks the polarity of supply cords. The following faults can be detected:
L OPEN, N OPEN, PE OPEN, L-N CROSS, L-N SHORT, L-PE SHORT, N-PE SHORT
and MULTIPLE FAULT.
