a) Turning on the multimeter
The multimeter is turned on and off with the rotary switch (4). Turn the rotary switch to the appropriate
measuring function. To turn it off, move the rotary switch to the "OFF" position. Always turn the
measuring device off when it is not in use.
b) Voltage measurement "V"
Proceed as follows to measure direct voltage "DC" (V
1. Turn on the DMM and select the measuring range
"V ". For small voltages up to a max. 600 mV select
"mV ".
2. Insert the red test lead into the °CHzVΩ measuring socket (7),
the black test lead into the COM measuring socket (8) (Fig. 2).
3. Connect the two test prods with the object to be measured
(battery, circuit, etc.). The red test prod corresponds to the
positive pole, the black test prod to the negative pole.
4. The display indicates the polarity of the measured value
together with the currently measured value.
If a minus sign "-" appears in front of the measured value,
the measured voltage is negative (or the test leads are
reversed). The voltage range "V DC/AC" has an input
resistance of >10 MΩ.
5. After the measurement has been completed, remove the test leads from the object being
measured and turn the DMM off.
Proceed as follows to measure alternating voltage "AC" (V
1. Turn on the DMM and select the measuring range "V
If required you can select the "AC+DC" measuring function. Turn on the DMM and select
the measuring range "V
measuring function. The display will show " ".
2. Insert the red test lead into the °CHzVΩ measuring socket (7), the black test lead into the COM
measuring socket (8).
3. Connect the two test prods with the object to be measured (generator, circuit, etc.).
4. The measured value will be displayed.
5. After the measurement has been completed, remove the test leads from the object being
measured and turn the DMM off.
