5.7.4 Alternating Current Measurement with Clip-On Current Sensor,
A AC and Hz (METRAHIT⏐T
ECH and METRAHIT⏐BASE only)
Transformer Output, Voltage/Current
When a clip-on current sensor is connected to the multimeter
(METRAHIT⏐T
ECH: V input, METRAHIT⏐BASE: V input), all current
displays appear with the correct value in accordance with the se-
lected 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 clip-on current sensor must also
be taken into consideration.
