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.
