Benning CM 10-1 Notice D'emploi page 25

5.1.2 The polarity indication L functions automatically. Only a polarity con-
trary to the socket definition is indicated as "-".
5.1.3 The range overload will be displayed with "OL" or "- OL".
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 „()".
5.1.4 The BENNING CM 10-1 confirms each button press with a signal sound.
Invalid button presses are confirmed by a double signal sound.
5.1.5 The nominal measurement rate of the BENNING CM 10-1 is 3 measure-
ments per second (sec) for the digital display.
5.1.6 The BENNING CM 10-1 is switched on and off by the rotating switch 6 .
Switch-off position "OFF".
5.1.7 The "HOLD/ZERO" key 5 has two functions:
HOLD key function:
Press the HOLD/ZERO key 5 to store the measuring result. At the same
time, the digital display K shows the "
value exceeds the stored value by 50 digits, the change of the measured
value is indicated by the display flashing and an acoustic signal.
(Changes of measured values between AC and DC voltage / current will
not be recognized). Press the key again to switch the device back to the
measuring mode.
ZERO key function:
For null balance in case of current measurements with the A DC function.
For this, remove the BENNING CM 10-1 from all live conductors and
press the HOLD/ ZERO key 5 for 2 seconds until the "
displayed.

LOG function (data logger/measured value memory):
Press the key for approx. 2 seconds to enable the LOG function with the

section 5.2
5.1.9 The HFR key 8 has two functions:
HFR function (low pass filter):
The HFR function is intended for connecting a low-pass filter (high-fre-
quency suppression) in the V
high-frequency pulses e. g. at pulsed motor drives. "
LC display K . The limiting frequency (- 3 dB) of the filter is fg = 800 Hz.
When reaching the limiting frequency fg, the displayed value is lower by
a factor of 0.707 than the actual value without filter. Press the key again
to switch back to normal operating mode.
without HFR (without low-pass filter)
In order to prevent any danger, always measure a present volt-

age first without low-pass filter (high-frequency suppression) to
detect a dangerous voltage.
INRUSH function (inrush current measurement):
In measuring mode "A AC", press the HFR key 8 for approx. 2 sec-
onds to enable the inrush current measurement. At the same time, the
digital display K shows the
a suitable measuring range. The INRUSH function initiates a measuring
process for 100 milliseconds after a trigger current is applied. The aver-
aged value of this time period is displayed. Press the key 8 for approx.
2 seconds to switch back to the measuring mode.
Trigger current: (> 0.5 A in the 60 A measuring range, > 5 A in the 600 A
