Description of unit

The BENNING MM 4 consists of two functional units:
- the Multimeter and
- the current transducer clamp.
See fig.1:
The operating and indicating elements shown in fig. 1 are as follows:
1 Housing
2 Sliding switch for selecting the desired functions.
- Aus (OFF)
- Measurement of alternating voltage (AC) and direct voltage (DC).
These functions alternate with one-another when the function button
with the blue marking is pressed. When pressed longer (2 sec.) meas-
urement of alternating current, etc. The digital display 3 indicates the
function currently in effect.
- Resistance measurement, continuity test with buzzer and diode
test. These functions alternate with one-another when the function
button with the blue marking is pressed. The digital display 3 indicates
the function currently in effect.
3 Digital display (liquid-crystal principle). The following are indicated:
- the measurement value with the max. indication 4200,
- the polarity indication,
- the decimal point,
- the symbol for discharged battery,
- the type of voltage selected (DC or AC voltage),
- the measurement value held (hold function),
- the deviation from a measurement value stored in the unit memory
(REL ∆),
- the selected measuring range through display of extended / non-
extended measuring units of voltage, current and resistance,
- the selected continuity test with buzzer,
- the selected diode test.
4 Blue function button: the following symbols appear for this in the digital
display 3: "DC"; "AC"; "Ω", "V"; „
- Selection between DC-voltage and AC-voltage measurement or
- resistance measurement, continuity and diode test,
- or when button pressed for 2 sec. (in sliding-switch position ACV / DCV)
alternating current (Amp).
- Measurement of temperature (°C, °F), relative humidity (%), capacity
(µF), carbon monoxide (ppm), wind speed (m/s), illumination intensity
(k lux) are not possible with the BENNING MM 4.
- Repeat press for 2 sec. returns to voltage measurement
5 HOLD / REL button (hold function)
- First press of button causes indicated measuring value to be held (indi-
cated by 'Hold' in digital display 3, no updating of measured value),
- repeat press of button causes return to continuous measurement function.
- Relative-value function becomes effective when button pressed for 2
sec. The value currently being measured is stored and the difference
