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

The maximum allowable operating voltage is equal to the nominal
voltage of the current transformer. When reading the measured
value, additional error resulting from the current clamp sensor must
also be taken into consideration
(default setting: 1:1000).
