Ambient Conditions; Electrical Specifications - Benning CM 9-1 Notice D'emploi

Power-Off is activated, if the symbol
if the rotary switch 5 is switched on again from switch position „OFF". Automatic switch-
off can be deactivated by pressing the HOLD key and by simultaneously switching on
the BENNING CM 9-1 from the switching position "OFF". The symbol

5.1.12 The BENNING CM 9-1 is supplied by two 1.5 V batteries (IEC LR03/ AAA/ micro).
5.1.13 If the battery voltage drops below the specified operating voltage of the BENNING
CM 9-1, then a battery symbol
5.1.14 The battery life depends on the measuring function used and is approximately 40 hours
to 60 hours without using the acoustic continuity test and background lighting (alkaline
battery).
5.1.15 Temperature coefficient of the measured value: 0.1 x (stated measuring accuracy)/ °C
< 18 °C or > 28 °C, related to the value for the reference temperature of 23 °C
5.1.16 Dimensions of unit (length x width x height) = 210 x 76 x 33,5 mm.
Weight of unit: 296 g (incl. batteries)
5.1.17 The safety measuring leads and measurement tips supplied are especially suited to the
rated voltage of the BENNING CM 9-1. The measuring tips can be protected by caps.

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 %. The stated accuracy is specified for 1 % to 100 % of the final
measuring range value.

7.2 AC voltage 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 < 2.0 up to 100 % of each final measuring range value
Crest factor < 4.0 up to 50 % of each final measuring range value
