Ambient conditions

- The BENNING MM P3 is intended for measurements under dry ambient condi-
tions,
- Maximum barometric height for measurements: 2000 m,
- Overvoltage category / installation category: IEC 60664-1/ IEC 61010-1 → 300 V
category III; 600 V category II,
- Contamination class: 2,
- Protection category: 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 air humidity:
For operating temperatures from 0 °C to 30 °C: relative air humidity less than 80 %,
For operating temperatures from 31 °C to 40 °C: relative air humidity less than 75 %,
For operating temperatures from 41 °C to 50 °C: relative air humidity less than 45 %,
- Storage temperature: The BENNING MM P3 can be stored at temperatures be-
tween - 20 °C and + 60 °C (air humidity of 0 to 80 %). During storage, the bat-
teries should be removed.
7. Electrical specifications
Note: The measuring accuracy is specified as the sum of:
- a relative part of the measured value and
- a number of digits (i.e. counting steps of the last digit).
This measuring accuracy applies for temperatures from 18 °C to 28 °C and a relative
air humidity less than 80 %.
