BENNING MM 1
10
BENNING MM 1 a low battery symbol appears in the display.
5.1.12 The lifespan of a battery is approx. 1000 hours (Alkaline battery).
5.1.13 Meter dimensions:
(L x W x H) = 155 x 80 x 26 mm without protective rubber holster
(L x W x H) = 165 x 80 x 36 mm with protective rubber holster
Meter weight:
170 g without protective rubber holster
310 g with protective rubber holster
5.1.14 The safety test leads feature 4 mm diameter needle pointed tips. The
safety test leads provided with the meter are specifically suited for the
rated voltage and current of the BENNING MM 1. The probe tips can
be covered with protective caps.
5.1.15 The BENNING MM 1 is protected from mechanical damage by a pro-
tective rubber holster
. The protective rubber holster
allows the
BENNING MM 1 to be placed upright or hung up during measuring.
6. Environmental conditions
- The BENNING MM 1 is designed for measuring in dry conditions,
- Altitude during measuring: 2000 m maximum
- Overvoltage category/ Location category: IEC 664/ IEC 1010- 1:1990 →
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 1 can be stored at temperatures
between - 20 °C and + 60 °C. The battery should be removed when tester
is in storage.
7. 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 %.
