BENNING CM 1-1/ 1-2



against solid impurities of a diameter > 2.5 mm

0 – second index: no protection against water,

- 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 CM 1-1/ 1-2 can be stored at tempera-

tures between - 20 °C and + 60 °C (air humidity of 0 to 80 %). During stor-

age, the battery should be removed.

7. Electricalspecications

Note: The measuring accuracy is specied as the sum of:

- a relative part of the measured value and

- a number of digits (i.e. counting Stepps of the last digit).

This measuring accuracy applies for temperatures from 18 °C to 28 °C and a

relative air humidity less than 80 %.

The measured value is obtained by mean value rectication and is displayed

as r.m.s. value. Its calibration is adapted to a sinusoidal curve.

The stated accuracy is specied for conductors that are centrally clamped

by means of the current clamp

(see gure 4 AC current measurement).

For conductors that are not centrally clamped, an additional error of 1,5 % of

the displayed value has to be considered.
