Phase Test - Benning MM 1-2 Bedienungsanleitung

BENNING MM 1-1/ 1-2/ 1-3.
- Bring the safety measuring leads into contact with the measuring points. If the
lead resistance between the COM jack J and the jack for V, ,
below 25 , the integrated buzzer of the BENNING MM 1-1/ 1-2/ 1-3 sounds.
See figure 8:
8.6 Capacity measurement (BENNING MM 1-2/ 1-3)
Before performing capacity measurements, discharge capaci‑
tors completely!

Never apply voltage to the capacity measurement jacks!
This might damage or destroy the device! A damaged device
might represent an electrical hazard!
- Select the desired function (
BENNING MM 1-2/ 1-3.
- Determine the polarity of the capacitor and completely discharge the ca-
pacitor.
- Connect the black safety measuring lead to the COM jack J of the
BENNING MM 1-2/ 1-3.
- Connect the red safety measuring lead to the jack for V, ,
BENNING MM 1-2/ 1-3.
- Bring the safety measuring leads into contact with the discharged capacitor
according to ist polarity and read the measured value on the digital display
 of the BENNING MM 1-2/ 1-3.
See figure 9:
8.7 Frequency measurement (BENNING MM 1-2/ 1-3)
- Select the desired function (Hz) by means of the rotary switch 8 of the
BENNING MM 1-2/ 1-3.
- Connect the black safety measuring lead to the COM jack J of the
BENNING MM 1-2/ 1-3.
- Connect the red safety measuring lead to the jack for V, ,
the BENNING MM 1-2/ 1-3. Please observe the minimum sensitivity for fre-
quency measurements of the BENNING MM 1-2/ 1-3!
- Bring the safety measuring leads into contact with the measuring
points and read the measured value on the digital display  of the
BENNING MM 1-2/ 1-3.
See figure 10:
8.8 Temperature measurement (BENNING MM 1-3)
- Select the desired function (°C or °F) by means of the rotary switch 8 of the
BENNING MM 1-3.
- Connect the temperature measuring adapter and the temperature meas-
uring lead to the COM jack (-) J and to the jack for V, ,
observing correct polarity.
- Arrange the end of the temperature measuring lead in the vicinity of the heat
source to be monitored. Read the measured value on the digital display 
of the BENNING MM 1-3.
See figure 11:
8.9 Voltage indicator
The voltage indicator function is possible from each position of the rotary switch.
No measuring leads are required as voltage indicator (non-contact detection
of an alternating field). The detector is located on the upper part of the device
behind the LED. By pressing the „VoltSensor" key 5, the display indication dis-
appears (if the display is switched on). If a phase voltage is localized, this is
indicated by an acoustic signal and a red LED signal M. An indication is made in
earthed AC current networks only! The phase can be determined by means of a
single-pole measuring lead.
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

Phase test

- Connect the red safety measuring lead to the jack for V, ,
BENNING MM 1-1/ 1-2/ 1-3.
- Bring the safety measuring lead into contact with the measuring point of the
system part and press the „VoltSensor" key 5.
- If the red LED lights and if there is an acoustic signal, the phase of an
earthed AC voltage is applied to this measuring point (system part).
