BENNING MM 10–PV/ MM 10–1
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, “0L” indicates an interruption inside the
diode.
- For a diode applied in reverse direction, “0L” is displayed. If the diode is
defective, “000” or other values are displayed.

8.8 Temperature measurement (switch position )
- Use the rotary switch
6
to select the required function
on BENNING
MM 10-PV/ MM-10-1.
- Press
function key (blue)
4
to switch over to °F or °C.
- Connect the temperature sensor (type K) correctly to the COM jack COM
K
and jack
L
, observe polarity.
- Place the contact point (end of the sensor lead) on the point to be measured.
Read the measurement value on the digital display

MM 10-PV/ MM-10-1.
see fig. 8: Temperature measurement
8.9 Voltage indicator (switch position
)
The voltage indicator function is not intended for testing the ab-
sence of voltage. Even without an indication or acoustic signal,
a dangerous contact voltage might be applied. Electrical danger!
- Use the rotary switch
9
to select the required function
on BENNING
MM 10-PV/ MM 10-1, the symbol “
“ is flashing on the digital display
1
.
- Press the RANGE key
5
to switch over to Hi (high sensitivity) or Lo (low
sensitivity).
- The voltage indicator function does not need any measuring leads (non-
contact detection of an alternating field). The detector is located on the top
side of the BENNING MM 10-PV/ MM 10-1. In case of a phase voltage being
localized, an acoustic signal is emitted and the red LED
O
on the top side of
the device lights. An indication is shown in earthed AC mains only!
Practical hint:
Interruptions (cable breaks) in cables lying around openly such as e.g. cable
reels, fairy lights etc. can be traced from the feeding point (phase) to the point
of interruption.
Functional range:≥ 230 V
see fig. 9: Voltage indicator with buzzer and LED
8.9.1 Phase test (switch position
)
- Connect the black safety measuring lead to the COM jack
K
of the BENNING
MM 10-PV/ MM 10-1.
- Connect the red safety measuring lead to the jack +
L
of the BENNING
MM 10-PV/ MM 10-1.
- Use the rotary switch
9
to select the required function
on BENNING
MM 10-PV/ MM 10-1, the symbol “
“ is flashing on the digital display
1
.
- Press the RANGE key
5
to switch over to Hi (high sensitivity) or Lo (low
sensitivity).
- Connect the red safety measuring lead with the measuring point (system
part).
- If an acoustic signal is emitted and the red LED
O
lights, the phase of an
earthed alternating voltage is applied to this measuring point (system part).
9. Maintenance
Before opening the BENNING MM 10-PV/ MM 10-1, strictly ob-
serve that the device is free of voltage!
Electrical danger!
Working on the opened BENNING MM 10-PV/ MM 10-1 under voltage must be
carried out by
skilled electricians special precautions for the prevention of
accidents only!
Make sure that the BENNING MM 10-PV/ MM 10-1 is free of voltage as described
below before opening the device:
- First, remove both safety measuring leads from the object to be measured.
- Then, remove both safety measuring leads from the BENNING MM 10-PV/
MM 10-1.
- Turn the rotary switch
9
to the switch setting “OFF”.
