Ambient Conditions; Electrical Data - Benning MM 6 Bedienungsanleitung

the button is pressed a second time, the unit switches back to
measurement mode.
5.1.7 The button "HZ"  changes the display to frequency in the AC
voltage and current range. When the button is pressed a second time,
the unit switches back to the previous mode.
5.1.8 When the rotating switch is at V, mA and A, the blue button 
switches between DC and AC operation. In position Ω, it switches
from resistance measurement to continuity test and when pressed
another time, to diode test. In switch position Hz, it switches from
frequency measurement to RPM mode. The RPM mode is equivalent
to a mathematical conversion from Hz (cycles per second) to RPM
(rotations/cycles per minute). 1 Hz is equivalent to 60 r.p.m. (rotations/
cycles per minute).
5.1.9 The nominal measurement rate of the BENNING MM 6 is 2
measurements per sec. for the digital display and 12 measurements
for the bar graph display.
5.1.10 The BENNING MM 6 is switched on and off by the rotating switch .
Switch-off position "OFF".
5.1.11 The BENNING MM 6 switches off automatically after approx. 30
minutes (APO = Auto-Power Off). It switches back on again when the
HOLD button or another button is pressed. A buzzer signal is given 15
sec. before it switches off automatically.
5.1.12 Temperature coefficient of measurement value: 0.15 x (stated
measurement accuracy)/ °C < 18 °C or > 28 °C relative to the value at
the reference temperature of 23 °C.
5.1.13 The BENNING MM 6 is powered by one 9-V block battery (IEC 6 LR
61).
5.1.14 When the battery voltage drops beneath the specified operating voltage
of the BENNING MM 6, the low battery symbol appears in the display.
5.1.15 The life span of a battery is approx. 300 hours (alkali battery).
5.1.16 Dimensions:
(L x W x H) = 180 x 88 x 33,5 mm without protective rubber holster
(L x W x H) = 188 x 94 x 40 mm with protective rubber holster
Weight:
300 g without protective rubber holster
440 g with protective rubber holster
5.1.17 The safety test leads are 4 mm plug-type leads. The safety test
leads are expressly suitable for the rated voltage and power of the
BENNING MM 6.
5.1.18 The BENNING MM 6 is protected against mechanical damage by a
protective rubber holster . The protective rubber holster  makes it
possible to suspend the BENNING MM 6 during the measuring process
or to stand it upright.

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 %.
7.1 DC voltage range
The input resistance is 10 MΩ (in 400 mV-range 1GΩ).
