Ambient conditions

- The BENNING CM P1/ P2 is intended for making measurements in dry environment.
- Maximum barometric elevation for making measurements: 2000 m,
- Overvoltage category: IEC 60664/ IEC 61010 → 600 V category III
- Contamination class: 2 (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 40 °C: relative air humidity lower than 80 %, non-
condensing
- Storage temperature: The BENNING CM P1/ P2 can be stored at temperatures between
- 10 °C and + 60 °C, at a relative air humidity lower than 70 % without batteries.

Electrical specifications

Note: The measuring precision is specified as the sum of
- a relative fraction of the measured value and
- a number of digits (counting steps of the least significant digit).
This specified measuring precision is valid for temperatures in the range from 23 °C ± 5 °C and
relative humidity less than 80 %.
7.1 AC current range
The measured value is obtained and displayed as real r.m.s. value (True RMS, AC coupling).
Its calibration is adapted to sinusoidal curves. In case of deviations from this curve shape, the
accuracy of the displayed value decreases.
Crest factor < 1.6 up to 100 % of each final measuring range value
Crest factor < 3.2 up to 50 % of each final measuring range value
