5.7.3 Direct and Pulsating Current Measurement
with Current Clamp Sensors, A DC and A (DC+AC)
Transformer Output, Voltage/Current
When a current clamp sensor is connected to the multimeter
(V input (
METRAHIT EBASE : V input)), all current displays appear with
the correct value in accordance with the selected transformation fac-
tor. The only prerequisite is that the current sensor is equipped with at
least one of the below listed transformation factors, and that the fac-
tor has been previously selected in the following menu (Cl ip ¼ 0FF),
see also chapter 6.4.

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