measurement of protective conductor re-
sistance.
Correct result. The value
of leakage current is
below the set limit. Green
LEDs of PASS indication
are on.
Connect test leads according to the drawing.
Differential leakage current is measured as a difference between L current and N
current. This measurement takes into account not only PE leakage current, but
also leakage currents caused by other earthed elements - e.g. water pipe. The
disadvantage of this measurement is the presence of common current (supplied
to the device through L line and returning via N line), that is influencing the accu-
racy of the measurement. Connection:
