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 II according to EN 61010-1
- Protection class: IP 30 (EN 60529),
- 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 specications
Note: The measuring precision is specied 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 specied 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.
