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 or A) you need
2) Select basic frequency via switch(10).
3) Open the clamp, and close it round the conductor. Make sure that the clamp
properly encircles the conductor, and that there is no air gap between the jaws.
For best measurement results and highest accuracy, have the conductor pla-
ced in center of clamp jaws.
If the display is not visible during measurement, press the "HOLD" button (4)
to retain the display. The clamp can then be removed from the conductor and
the stored value read.
Addtional it´s possible to activate the MAX.-MIN.- PEAK measurement. Press
the key (4) to select the mode.
