Leakage Current Measurement

Before switching to a new function, the probes must always be removed from the
UUT.
1) Turn selector switch (3) to the current range mA
2) Open the clamp, and close it round the conductor. Make sure that the clamp proper-
ly encircles the conductor, and that there is no air gap between the jaws. For best
measurement results and highest accuracy, have the conductor placed in center of
clamp jaws.
Only use the frequency range switch (10) for hamrmonics wave
measurement.
