5.7.3 Direct and Pulsating Current Measurement with Current Clamp
Sensor, A DC and A (DC+AC)
Voltage/Current Transformer Output
When a current clamp sensor is connected to the multimeter (V in-
put), all current displays appear with the correct 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 trans-
formation ratios, and that the ratio has been previously selected in the
following menu
( Cl ip  0FF ) (see also section 6.4).
Current Clamp Setup Menu

CLIP set:1 / 10/100/1000 / 0ff 
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).
