Environmental Conditions; Electrical Specifications - Benning MM 2 Manuel De Instrucciones

safety test leads provided with the meter are specifically suited for the
rated voltage and current of the BENNING MM 2. The probe tips can
be covered with protective caps.
5.1.13 The BENNING MM 2 is protected from mechanical damage by a pro-
tective rubber holster . The protective rubber holster  allows the
BENNING MM 2 to be placed upright or hung up during measuring.

Environmental conditions

- The BENNING MM 2 is designed for measuring in dry conditions,
- Altitude during measuring: 2000m maximum
- Overvoltage category/ Location category: IEC 664/ IEC 1010-1:1990 →
1000 V Category II; 600 V Category III,
- Pollution degree: 2,
- 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 protec-
tion against water, (0 - second index).
- Working temperature and relative humidity:
for working temperature between 0 °C and 30 °C: relative humidity smaller
than 80 %
for working temperature between 30 °C and 40 °C: relative humidity smaller
than 75 %
for working temperature between 40 °C and 50 °C: relative humidity smaller
than 45 %
- Storage temperature: the BENNING MM 2 can be stored at temperatures
between - 20 °C and + 60 °C. The battery should be removed when tester
is in storage.

Electrical specifications

Note: measurement accuracy is given as the sum of
- a relative percentage of the reading and
- the number of least significant digits
This accuracy is valid for temperatures between 18 °C and 28 °C, with a relative
humidity smaller than 75 %.
