8. Making measurements with the BENNING CC 2
8.1 Preparations for making measurements
Operate and store the BENNING CC 2 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 2.
- The safety measuring cable is securely connected to the BENNING CC 2
and cannot be removed.
- Check the insulation of the safety measuring cables. Discard the
BENNING CC 2 immediately if the insulation is damaged.
- Do not clamp the measuring pliers on a live conductor before the
BENNING CC 2 has not been connected to a multimeter.
Strong sources of interference in the vicinity of the BENNING CC 2 can lead
to unstable readings and measuring errors.
- Do not apply any voltage to the output contacts of the BENNING CC 2.

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 2 against ground
potential, is 600 V.
