5.2.8 Differential leakage
The purpose of this test is to determine the sum of all leakages flowing from the live
conductors to the earth. The differential method allows measuring the full and true leakage
current, even if there are parallel current paths from the DUT to ground.
The instrument measures:
 The differential leakage of the DUT connected to the instrument test socket.
