Frequently Asked Questions - MM 13 BENNING

How to measure DC voltage with the BENNING MM 13?

Select the V DC function with the rotary switch. Connect the black cable to the COM socket and the red one to the V, Ω, Hz socket. Place the test probes on the points to be measured and read the value on the display.

What does 'OL' display on the multimeter mean?

The OL (Over Load) display indicates an overload of the measurement range or an open circuit. It can also mean that the diode is reverse biased during diode testing.

How to replace the batteries of the BENNING MM 13?

Turn off the device (OFF) and remove the test leads. Unscrew the battery compartment cover at the back of the device. Replace the two 1.5 V type R3 batteries, observing polarity. Close and screw back.

How to use the continuity test function?

Turn the switch to the continuity test symbol (diode + wave). Connect the cables as for a resistance measurement. If the resistance is less than 25 Ω, the buzzer emits an audible signal.

What is the maximum voltage I can safely measure?

The BENNING MM 13 can measure up to 1000 V DC and 750 V AC in category II. Observe the overvoltage categories: CAT III 600 V and CAT II 1000 V.

How to measure a high current (up to 10 A)?

Select the A AC or A DC function. Connect the red cable to the 10 A socket (instead of V, Ω, Hz) and the black to COM. Do not exceed 10 A and observe the maximum duration for currents ≥ 7 A.

How to clean the multimeter?

Clean the exterior with a clean, dry cloth. Do not use solvents or abrasives. Ensure the battery compartment remains clean and dry.

How to use the non-contact voltage indicator (VoltSensor)?

Press the VoltSensor button. Approach the multimeter to a conductor. If there is an AC voltage ≥ 230 V relative to earth ground, the red LED lights up and a beep sounds.

How to replace the protective fuse?

Turn off the device and remove the cables. Open the battery compartment and remove the batteries. Unscrew the lower housing. Replace the defective fuse with a 10 A / 600 V fast-acting fuse (ref. 748263). Reassemble in reverse order.

What to do if the device does not turn on or displays the battery symbol?

The battery symbol indicates that the batteries are drained. Replace the two 1.5 V type R3 batteries. If the device still does not turn on, check the battery polarity and the contact condition.

See figure 11: Temperature measurement

8.9 Voltage indicator

The voltage indicator function is possible from each position of the rotary switch. No measuring lines 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 disappears (if the display is switched on). If a phase voltage is localized, this is indicated by an acoustic signal and a red LED signal ⑬. An indication is made in earthed AC current networks only! The phase can be determined by means of a single-pole measuring line.

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 figure 12: Voltage indicator with buzzer

• Bring the safety measuring line 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).

9. Maintenance

Before opening the BENNING MM 1-1/ 1-2/ 1-3, make sure that the device is free of voltage! Electrical danger!

Working on the opened BENNING MM 1-1/1-2/1-3 under voltage must be carried out by skilled electricians only who must observe special precautions for the prevention of accidents!

Therefore, make sure the BENNING MM 1-1/ 1-2/ 1-3 is free of voltage before opening the device:

• First, remove both safety measuring lines from the object to be measured.
• Then, remove both safety measuring lines from the BENNING MM 1-1/ 1-2/ 1-3.
• Switch the rotary switch ⑧ to position „OFF“.

9.1 Securing the device

Under certain circumstances, safe operation of the BENNING MM 1-1/ 1-2/ 1-3 might no longer be ensured, e.g. in case of:

• visible damages of the housing,
• incorrect measuring results,
• recognizable consequences of prolonged storage under inadmissible conditions and
• recognizable consequences of extraordinary stress due to transport.
  In such cases, immediately switch off the BENNING MM 1-1/1-2/1-3, disconnect it from the measuring points and secure it against further use.

9.2 Cleaning

Clean the exterior of the device with a clean dry cloth (exception: special cleaning wipers). Do not use any solvents and/or abrasives to clean the device. Make sure that the battery compartment and the battery contacts are not contaminated by leaking battery electrolyte.

If there are electrolyte contamination or white deposits in the area of the battery or the battery housing, clean these areas as well by means of a dry cloth.

9.3 Battery replacement

Before opening the BENNING MM 1-1/ 1-2/ 1-3, make sure that the device is free of voltage! Electrical danger!

The BENNING MM 1-1/1-2/1-3 is supplied by means of two integrated 1.5 V micro (AAA) batteries.

9.5 Calibration

To maintain accuracy of the measuring results, the device must be recalibrated in regular intervals by our factory service. We recommend recalibrating the device once a year. For this purpose, send the device to the following address:

10. Using the suspension fixture

• You can store the safety measuring lines by winding them around the device and by engaging the probe tips of the safety measuring lines in a protected way on the suspension fixture 12 (see figure 15).
• You can engage a safety measuring line on the suspension fixture 12 in such a way that the probe Tipp remains free in order to be able to guide the probe tip towards a measuring point together with the BENNING MM 1-1/ 1-2/ 1-3.
• The rear support of the device allows an inclined setup of the BENNING MM 1-1/1-2/1-3 (facilitates reading the measured values) or suspension of the device (see figure 16).
• The suspension fixture 12 is equipped with a lug which can be used for suspension.
