5.7.3 Direct and Pulsating Current Measurement 
with Clip-On Current Sensor, A DC and A (DC+AC)
Transformer Output, Voltage/Current
When a clip-on current sensor is connected to the multimeter 
(V input), 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 transformation ratios, and that the ratio 
has been previously selected in the following menu (Cl ip ≠ 0FF) 
(see also chapter 7.4).

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 (
default value: Cl ip = 0ff = voltage dis-
play).
