3.9  one operating manual.

Note on optional accessory:

-   Temperature probe (K-type) made of V4A tube

 application: insertion probe for soft-plastic materials, liquids, gas and air

 measuring range: - 196 °C up to 800 °C

   dimensions: length = 210 mm, tube length = 120 mm, tube diameter = 

3 mm, V4A (P.no. 044121)

Note on replaceable parts:

-  The   BENNING MM 5-2 contains fuses for overload protection:

 One fuse rated 15 A rapid-acting (600 V) 50 kA, D = 10.3 mm,  L = 38.1 mm 

(P.no. 10149447).

-  The BENNING MM 5-1/ MM 5-2 is supplied by means of two integrated 

1.5 V micro (AAA) batteries (IEC LR 03). 

-   The above mentioned safety cable (tested spare part) are approved in 

accordance with CAT III 1000 V/ CAT IV 600 V and for a current up 10 A.

5.   General data

5.1  General data on multimeter

5.1.1   The digital display 

1

 is designed as a 4 digit liquid-crystal indicator with 16 

mm digit height and decimal point. The highest value displayed is 6000.

5.1.2   The polarity indication 



 functions automatically. Only a polarity con-

trary to the socket definition is indicated, as “-”.

5.1.3   The range overload will be displayed with “OL” or “-OL” and sometimes 

with an acoustic signal.

Attention: no display or warning by complete overload.

5.1.4  The rotary switch 

9

 is intended for selecting the measuring function. 

The measuring range is selected automatically.

5.1.5 

  Volt  sensor  key 

5

: The voltage indicator function is intended for local-

izing AC voltages to earth (see 8.9).

5.1.6  Press the Δ/PEAK key 

6

 (relative value function) to store the currently 

displayed value and to display the difference (offset) between the stored 

measured value and the following measured values. Press the Δ/PEAK 

key 

6

 for 2 seconds to switch over to the “PEAK” function (peak value 

storage). The “PEAK” function detects and stores the positive and nega-

tive peak/ crest value (> 1 ms) in the mV/ V AC and mA/ A AC function. 

Press the key to call up Pmax, Pmin and the currently measured value 

(Pmax, Pmin). Press the key for approx. 2 seconds to switch the device 

back to normal operating mode.

5.1.7  “Smart HOLD” - storage of measurement reading: When the “Smart HOLD” 

key 

 

is pressed, the measurement reading is stored in the memory. 

The symbol “HOLD” appears in the display 

1

 at the same time. If the 

measured value increases by 50 digit above the saved value the change 

in measured value is shown by a blinking display and by a signal tone. 

(changes of measured values between AC and DC voltage/ current will 

not be recognized).

5.1.8  Press the yellow key 

8

 to activate the display illumination. The device is 

switched off automatically after 2 seconds or by pressing the key again. 

Deactivate the automatic switch-off by pressing the key (yellow) 

8

 and 

simultaneously switching the BENNING MM 5-2 ON from the switch
