5.8.4 AC 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 / mA input) all current displays appear with the cor-
rect value in accordance 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 7.4).

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.
