5.7.4 Alternating Current Measurement with Clip-On Current Sensor
A AC and Hz (METRAHIT AM TECH / T

only)
Transformer Output, Voltage/Current
When a clip-on current sensor is connected to the multimeter
(

in-
put), all current displays appear with the correct value in accord-
ance 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 (

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