teresis due to magnetization. As a result, the
zero adjustment point for DC measurements
may vary. Open and close the clip jaws several
times in a row and press the ZERO ADJ key prior
to each DC measurement in order to elimitate
this effect. When measuring current conduct-
ing cables, close and open the clip jaws slowly
and firmly in order to avoid any impact on the
sensitive hall effect sensor.
Remedy in the Event of Exceeding the Measuring
Range
If the maximum measurable current has been
exceeded by a large degree, zero balancing
can no longer be effected due to the satura-
tion of the current clip.
Remedy:
Turn the measuring instrument on with the
POWER key.
Adjust the smallest measuring range with
the RANGE DOWN key (200 mA AC).
Close the clip around a conductor with
10 A AC and reduce the current in the
conductor gradually to 0 A. This elimi-
nates magnetic saturation.
