8. Making measurements with the BENNING CC 1
8.1 Preparations for making measurements
Operate and store the BENNING CC 1 only at the specified storage and
operating temperatures. Avoid continuous insulation.
- The nominal voltage and current ratings of the safety measuring cables
included in the scope of delivery correspond to the ratings of the
BENNING CC 1.
- The safety measuring cable is securely connected to the BENNING CC 1
and cannot be removed.
- Check the insulation of the safety measuring cables. Discard the
BENNING CC 1 immediately if the insulation is damaged.1
- Do not clamp the measuring pliers on a live conductor before the
BENNING CC 1 has not been connected to a multimeter.
Strong sources of interference in the vicinity of the BENNING CC 1 can lead
to unstable readings and measuring errors.
- Do not apply any voltage to the output contacts of the BENNING CC 1.

Do not exceed the maximum permitted voltage with respect to
earth potential! Electrical danger!
The highest voltage, that may be applied to the BENNING CC 1 against ground
potential, is 600 V.
8.2 Alternating current measurement
- Set the multimeter to the function "alternating voltage measurement" (V AC)
and select a measurement range that can display voltages from 1 mV to
400 mV.
- Contact the 4 mm safety connector of the spiral type safety measuring cable
with the COM jack of the multimeter.
- Contact the red 4 mm safety connector of the spiral type safety measuring
cable with the voltage input jack (V) of the multimeter.
- Opening lever  Operate and use meas. pliers to  clamp the single wire
live conductor.
- Read off the voltage value on the multimeter and convert to the current
value taking into account the conversion factor.
