cate gory IV; 1000 V category III.
- Degree of contamination: 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).
- Operating temperature and relative humidity:
At operating temperatures of 0 °C to 30 °C: relative humidity under 80 %.
At operating temperatures of 30 °C to 40 °C: relative humidity under 75 %.
- At operating temperatures of 40 °C to 50 °C: relative humidity under 45 %.
- Storage temperature: The BENNING MM 7-1 can be stored at tempera-
tures from - 20 °C to + 60 °C (humidity 0 up to 80 %). The batteries must
be removed from the unit.

Electrical data

Note: The measurement accuracy is stated as the sum of
- a relative proportion of the measurement value and
- a number of digits (i.e. numerical steps of the last place).
This measurement accuracy applies for a temperature of 18 °C to 28 °C and a
maximum relative humidity of max. 80 %.

7.2 AC/ AC+DC voltage ranges
The input resistance is 10 MΩ parallel < 100 pF. The measurement value is
obtained as a true RMS value and displayed as such. With non-sinusoidal
curves, the value displayed is less accurate. This results in an additional error
for the following crest factors:
Crest factor of 1.4 to 2.0, additional error + 1.0 %.
Crest factor of 2.0 to 2.5, additional error + 2.5 %.
Crest factor of 2.5 to 3.0, additional error + 4.0 %.

The low-impedance input resistance of approx. 3 kΩ serves to suppress induc-
tive and capacitive voltages.
