5.2 Measuring with a multimeter
Requirements
• Please observe the requirements for measuring [} page 16].
Procedure
1. Set the multimeter to the AC measurement function (mA‑AC or A‑AC).
2. Select an appropriate measuring range.
3. Connect the device to the multimeter:
– BENNING CC 4‑1:
Connect the black 4 mm safety connector of the device to the COM jack of the
multimeter.
Connect the black 4 mm safety connector of the device to the COM jack of the
multimeter for the current input (mA or A).
– BENNING CC 4‑2:
Connect the device by means of suitable safety measuring lines via the two 4 mm safety
jacks to the multimeter (COM jack and jack for current input (mA or A)).
4. Operate the opening lever and clamp the live conductor with the measuring clamp.
5. Read the current value on the multimeter.
6. Convert the read value to the actually measured current value taking into account the
conversion factor.
– Conversion factor: 1 mA‑AC = 1 A‑AC
– Example: A current value of 155 mA‑AC displayed on the multimeter corresponds to an
actually measured current value of 155 A‑AC.
7. Disconnect the device from the measuring object after having completed the measurement.
