Ambient Conditions; Electrical Data - Benning MM 1 Notice D'emploi

5.1.11 The safety test lead and the test probe are in 4 mm plug-in design. The
safety test lead and the test probe are suitable for the nominal voltage
and nominal current of the BENNING MM 4. The test probe can be
protected by caps.
5.2 General data on current transducer
5.2.1 Current-measuring range: from 0.1 A
5.2.2 Output voltage: the current transducer of the BENNING MM 4 pro-
duces an alternating voltage of 1 mV when the single-wire conductor
which the current transducer is gripping is under an AC current of 0.1 A.
5.2.3 Sensor type: induction coil for alternating current.
5.2.4 Temperature coefficient of measurement value: 0.15 x (stated measure-
ment accuracy)/ °C with reference to the value at a temperature of 23 °C.
5.2.5 Max. apparent resistance at output: 120 Ω
5.2.6 Widest angle of tongs: 30 mm
5.2.7 Greatest conductor diameter 29 mm
5.2.8 Dimensions of current transducer (L x W x H) = 102 x 77 x 35 mm.
Weight of current transducer: 130 g
Note:
The current transducer can only be used for measurements when it is plugged
into the Multimeter.

Ambient conditions

- The BENNING MM 4 is designed only for measuring in dry surroundings,
- Maximum barometric height during measurement: 2000 m.
- Overvoltage category / set-up category: IEC 60664-1/ IEC 61010-1 →
300 V category III, 600 V category II,
- 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:
Multimeter
- At operating temperature of 0 °C to 50 °C: relative humidity under 80 %.
- current transducer:
At operating temperature of 0 °C to 45 °C: relative humidity under 75 %.
- Storage temperature:
The BENNING MM 4 can be stored at temperatures from -20 °C to + 60 °C.
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 reading and
- a number of digits (i.e. numerical steps of the last place).
This measurement accuracy applies for a temperature of 23 °C and a relative
humidity under 75 %.
Sections 7.1 to 7.5 refer to the connection of the Multimeter to the circuit being
measured (current transducer removed). Section 7.6 refers to the combination
of Multimeter with current transducer in place.
