Proceed as follows to measure AC voltages "V/AC":
- Turn the DMM on and select measuring range "V".
- Press "MODE" (4) to switch to the AC measuring range. "AC" appears in the display.
- Plug the red single measuring lead into the V measuring socket "E2" (10) and the black measuring
lead into the COM measuring socket "E1" (13).
- Now connect the two measuring probes to the object to be measured (generator, switch etc.).
- The measuring value is indicated on the display
- After measuring, remove the measuring leads from the measured object and turn the DMM off.
c) Measuring Current "µA/mA"
The voltage in the measuring circuit may not exceed 600 V.
Never measure currents above 400 mA in the µA/mA range, as this will cause the
fuse to trip.
Before beginning to measure, ending measurements and changing the measure-
ment range, always shut off the circuit.
Always start current measurements at the highest measurement range (mA) and switch
down to lower ranges if necessary. All current measuring ranges are secured with fuses
and thus protected against overload.
Proceed as follows to measure DC current (A/DC):
- Turn the DMM on and select measuring range "µA" or "mA". For currents
>4 mA select the range "mA", for currents <4 mA choose "µA".
- Plug the red single measuring lead into the mA measuring socket "E2"
(10) and the black measuring lead into the COM measuring socket "E1"
(13).
- Now connect the two test probes in series with the object to be measured
(battery, circuit etc.); the display indicates the polarity together with the
measured value.
If a minus "-" appears in front of the measured value when measur-
ing DC, the measured voltage is negative (or the measuring leads
have been mixed up).
- After measuring, remove the measuring leads from the measuring object
and turn the DMM off.
