Benning CC 1 Bedienungsanleitung Seite 9

6. Environment conditions:
- The BENNING CC 1 is intended for making measurements in dry
environment.
- Maximum barometric elevation for making measurements: 2000 m,
- Overvoltage category IEC 60664/ IEC 61010, 300 V category III,
600 V category II,
- Contamination degree 2 according to EN 61010-1
- Protection Class: IP 30 (DIN VDE 0470-1 IEC/ EN 60529)
IP 30 means: Protection against access to dangerous parts and protection
against solid impurities of a diameter > 2.5 mm, (3 - first index). No
protection against water, (0 - second index).
- Operating temperature and relative humidity:
For operating temperatures from 0 °C to 30 °C: relative humidity less than 80 %
For operating temperatures from 31 °C to 40 °C: relative humidity less than 75 %
For operating temperature from 41 °C to 50 °C: relative humidity less than 45 %
- Storage temperature: The BENNING CC 1 can be stored at any temperature
in the range from 20 °C to + 60 °C ).
7. Electrical specifications
Note: The measuring precision is specified as the sum of
- a relative fraction of the measured value and
- a current value in A.
The measurement precision applies at a temperature of 23 °C ± 5 °C and a
relative humidity less than 75 %.

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.
- 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.
