BENNING CM 10–PV
CM 10-PV.
- Press the
MODE
key (blue)
J
to enable the continuity test with buzzer/LED.
- Bring the safety measuring leads into contact with the measuring points. If
the line resistance between the COM jack
N
and the jack
O
falls below
a value between 20 Ω and 200 Ω, the integrated buzzer of the BENNING
CM 10-PV sounds and the red LED
3
lights up.
see fig. 7: Resistance measurement/ continuity and diode test/ capacitance
measurement
8.6 Capacitance measurement (switch position
)
Discharge capacitors fully before measurement! Never apply
voltage to the sockets for capacitance measurement as this may
cause irreparable damage to the unit. A damaged unit may repre-
sent an electrical hazard!
- Use the rotary switch
6
to select the required function
on BENNING
CM 10-PV.
- Determine the polarity of the capacitor and discharge it completely.
- Connect the black safety measuring lead to the COM jack
N
of the BENNING
CM 10-PV.
- Connect the red safety measuring lead to the jack +
O
of the BENNING
CM 10-PV.
- Press the
MODE
key (blue)
J
twice to enable the capacity measurement
function.
- Contact the discharged capacitor with the safety measuring leads observing
correct polarity. Read the measurement value on the digital display
K
of the
BENNING CM 10-PV.

measurement
8.7 Diode test (switch position
)
- Use the rotary switch
6
to select the required function
on BENNING
CM 10-PV.
- Connect the black safety measuring lead to the COM jack
N
of the BENNING
CM 10-PV.
- Connect the red safety measuring lead to the jack +
O
of the BENNING
CM 10-PV.
- Press the
MODE
key (blue)
J
3 times to enable the diode test.
- 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.
- For a normal silicone diode located in flow direction, the flow voltage be-
tween 0.400 V and 0.800 V is displayed. If “000” appears in the display, there
may be a short circuit in the diode, „OL“ indicates an interruption inside the
diode.
- For a diode applied in reverse direction, „OL“ is displayed. If the diode is
defective, „000“ or other values are displayed.
see fig. 7: Resistance measurement/ continuity and diode test/ capacitance
measurement
8.8 Temperature measurement (switch position )
- Use the rotary switch
6
to select the required function on BENNING
CM 10-PV.
- Press the blue key
J
to switch over to °F or °C.
- Connect the temperature sensor correctly to the COM jack COM
N
and jack
O
; observe polarity.
- Place the contact point (end of the sensor lead) on the point to be mea sured.
Read the measurement value on the digital display
K

8.9
Current measurement with the flexible AC current transformer
BENNING CFlex 1 (switch position )
- Use the rotary switch
6
to select the required function on BENNING
CM 10-PV.
- Connect the black safety measuring lead to the COM jack
N
of the BENNING
CM 10-PV.
- Connect the red safety measuring lead to the jack +
O
of the BENNING
CM 10-PV.
- Select the 3,000 A (1 mV/A) measuring range at the AC current transformer
BENNING CFlex 1.
