5. General information
5.1 General details on the current probe multimeter
5.1.1 The digital display is a 3¾-digit liquid crystal display with 14 mm high
numerals, complete with decimal point. The largest numerical value
which can be displayed is 4000.
5.1.2 The polarity indication is automatic. Only one polarity with respect to
the socket marked „-“ is indicated.
5.1.3 The overranging is indicated by „0L” or „- 0L” and, in part, an acoustic
warning.
Warning, no indication and prior warning in the event of an overload
condition!
5.1.4 Button (yellow) switches on the display illumination. Shutdown is
effected by a renewed press of the button or automatically after 60
seconds.
5.1.5
Measured value storage „HOLD”: Press the button „HOLD” to store the
measured result. At the same time, the display shows the symbol „HOLD”.
A renewed press of the button switches back into measuring mode.
5.1.6 The MIN/MAX button function inputs and stores automatically the
highest and lowest measured value . The following values are indicated
by button operation:
„MAX” indicates the stored maximum value, and „MIN” indicates the
lowest value. The continuous detection of the MAX-/ MIN value can
be stopped or started by pressing the button „HOLD” . Pressing the
button „MIN/MAX“ for an extended period of time (2 seconds) switches
back into normal mode.
5.1.7 The button PEAK (peak value storage) detects and stores the posi-
tive and negative peak/ crest values in the function V AC and A AC. At
the start of the measurement, press the button PEAK for approx. 3
seconds in order to increase measurement precision and to fine-adjust
the BENNING CM 6. Pressing the button indicates the „PMAX” or
„PMIN” values in the display. Pressing the PEAK button for an extended
period of time (2 seconds) switches back into normal mode.
5.1.8 The measuring rate of the BENNING CM 6 amounts nominally to
1.5 measurements per second for the digital display.
5.1.9 The BENNING CM 6 is switched on and off with the rotary switch .
Shutdown position „OFF”.
5.1.10 The BENNING CM 6 switches off automatically after approx. 30 min-
utes (APO, Auto-Power-Off). It switches back on again if a button or
the rotary switch is operated. A buzzer sound signals the automatic
switchoff of the unit. The automatic switchoff can be deactivated by
pressing a button (except the button „HOLD”) and simultaneously
switching on the BENNING CM 6 from switch position „OFF”.
5.1.11 Temperature coefficient of the measured value: 0.2 x (stated measuring
precision)/ °C < 18 °C or > 28 °C, related to the value for the reference
temperature of 23° C.
5.1.12
The BENNING CM 6 is supplied by two 1.5 V mignon batteries (IEC LR 06).
5.1.13 If the battery voltage drops below the specified operating voltage of the
BENNING CM 6, then a battery symbol appears in the display.
5.1.14 The life span of a battery amounts to approx. 600 hours (alkali battery).
5.1.15 Appliance dimensions:
(L x W x H) = 275 x 105 x 47 mm
Appliance weight:
534 g
5.1.16 The safety measuring cables supplied are expressly suited for the rated
voltage and the rated current of the BENNING CM 6.
5.1.17 Largest opening of pliers: 53 mm
5.1.18 Largest cable diameter: 51 mm
