See figure 1:
The display and operating elements shown in Fig. 1 are as follows:
 Measuring clamp, for clamping on the single-wire live conductor,
2 Bulge for current clamp, protects against contact with conductor,
3 LED (red) for voltage indicator and continuity test
4 Opening lever, for opening and closing the current clamp, for activation of
the measuring point illumination and LC display illumination
5 Rotary switch, for selecting the measuring function,
6 Bluetooth
®
7 RANGE key, switchover between automatic and manual measuring range
8 MODE key, for selecting the measuring function/secondary function
9 HOLD/ZERO key, measured value storage respectively ZERO for null ba-
lance (ADC)
J Digital display, for the measurement value, bar graph and display for over-
range indication
K Polarity indication,
L Battery condition indicator,
M Cursor key, menu control (up/ down/ , right/ ►, left/ ◄)
N OK/ENTER key, selection of the function
O COM jack, common jack for voltage/ resistance/ frequency/ capacity mea-
surements, diode tests and continuity tests,
P Jack (positive
) This is what the automatic polarity indication for DC current and DC voltage refers to

General information of the digital current clamp multimeter

5.1 General information

5.1.1 The digital display J is designed as a 4 digit liquid crystal indicator with
14 mm digit height and decimal point. The highest value displayed is
9999. The display illumination switches on automatically for 15 seconds
as soon as the rotary switch 5 , the opening lever 4 or any key is actu-
ated.
5.1.2 The bar graph display consists of 60 segments.
5.1.3 The polarity indication K functions automatically. Only a polarity con-
trary to the socket definition is indicated as "-".
5.1.4 The range overload will be displayed with "OL" or "- OL" and sometimes
with an acoustic signal.
Attention: No indication and prior warning in the event of an overload
condition! A exceeding of dangerous contact voltage (> 60 V DC/ 30 V
AC rms) is indicated by an additional flashing symbol „()".
5.1.5 The BENNING MM CM 12 confirms each button press with a signal
sound. Invalid button presses are confirmed by a double signal sound.
5.1.6 The nominal measurement rate of the BENNING CM 12 is 3 measure-
ments per second (sec) for the digital display.
5.1.7 The BENNING CM 12 is switched on and off by the rotating switch 5 .
Switch-off position "OFF".
5.1.8 The BENNING CM 12 switches off automatically after approx. 15 mi-
nutes (APO, Auto-Power-Off). It switches on again, if the rotary switch
5 is switched on again from switch position „OFF". The switch-off can
be adjusted individually in the setup menu (see section 5.1.9).
