Notes:
Consider any displayed warning before starting measurement!
If a Class I device is connected to the mains test socket the currents flowing
through the PE terminal will not be considered.
6.2.6
Differential leakage current
The purpose of this test is to determine the sum of all leakages flowing from the live
conductor to the earth. Because the differential method for determining leakage current
is used the full and true DUT leakage current is always measured, even when parallel
current paths to ground exist in the DUT.
