5.7.4 Alternating Current Measurement with Clip-On Current Sensor,
A AC and Hz
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).
