5.7.4 Alternating Current Measurement with Current Sensor Clamp
A AC and Hz
Transformer Output, Voltage/Current
When a current sensor clamp is connected to the multimeter V in-
put, METRAHITAM BASE: V input), all current displays appear with
the correct value in accordance with the selected transformation
factor.
The only prerequisite is that the current sensor is equipped with
at least one of the below listed transformation factors, and that the factor
has been previously selected in the following menu (
Cl
ip
0FF
), see also
chapter 6.4.

Maximum allowable operating voltage is equal to the current
transformer’s nominal voltage. When reading the measured value,
additional error resulting from the current sensor clamp must also
be taken into consideration.
