Measurement of differential leakage current
Note: In the half-time of the measurement, the tester automatically changes the polarity of the test
socket and as a final result it displays the value of higher leakage current.

 adjustable upper limit in the range of: 0,10 mA…19,9 mA with resolution of 0.01mA/0.1mA
 adjustable measuring time in the range of: 3…180s with resolution of 1 s
 when measuring devices whose power consumption exceeds 10A, the measurement time is
automatically limited to maximum of 15s.
