BENNING CM 10–PV
- Insert the BENNING TA PV measuring adapter into the COM jack
N
and the
+ jack
O
.
- Use the rotary switch
6
to select the required function
on BENNING
CM 10-PV.
- The DC coupling mode is automatically preselected and can be set to the AC
coupling mode using the
MODE
key (blue)
J
, if necessary.
- Bring the safety measuring leads into contact with the measuring points
and read the measured value on the digital display
K
of the BENNING
CM 10-PV.
Note:
If the PV measuring range is selected without the BENNING TA PV measuring
adapter being inserted, or if an incorrect measuring range is selected with the
BENNING TA PV measuring adapter being inserted, an acoustic signal is emitted
and the „Prob“ symbol is shown on the digital display
K
.
An acoustic signal is emitted if the wrong coupling mode (e.g. AC instead of DC)
is selected in the PV measuring range and a DC voltage greater than 30 V is
contacted via the BENNING TA PV measuring adapter. The incorrectly set cou-
pling mode is indicated in this case by a flashing symbol „DC“ and „
“.
The same applies to an AC application with incorrectly set DC coupling type. An
acoustic signal is emitted and a flashing “AC” symbol and „
“ is shown on the
digital display.

adapter
8.3 Current/ frequency measurement (switch position
)
Do not apply any voltage to the input jacks
N
and
O
of the
BENNING CM 10-PV! Any possibly connected safety measuring
leads have to be removed.
- Use the rotary switch
6
to select the required function
and press the
MODE
key (blue)
J
to select the coupling mode on BENNING CM 10-PV.
- Press the “
ZERO
” button
5
(2s) to set the BENNING CM 10-PV to the start-
ing point (only DC coupling mode).
- Operate opening lever
4
, clamp
1
single wire live conductor centrally by
means of the BENNING CM 10-PV current probe.
- In the
function, the
MODE
key (blue)
J
can be used for switching over
to frequency measurement (Hz).
- Read off the digital display unit
K
