Proceed as follows to measure alternating voltages “AC” (V~):
1. Switch on the DMM and select measuring function “V~”. The indication “AC” and “TrueRMS” show
on the display.
2. Plug the red measuring lead into the
V
ȍ
°CHz measuring jack (17) and the black
measuring lead into the COM measuring jack (18).
3. Now connect the two measuring prods to the object to be measured (generator, circuit, etc.).
4. The voltage measured value is indicated on the display.
5. After measuring, remove the measuring leads from the measured object and turn off the DMM.
Current measuring
Do not exceed the maximum permitted input values. Do not touch any circuits or
parts of circuits if they may be subject to voltages higher than 25 V ACrms or 35 V
DC! Danger to life!
The maximum permissible voltage in the measuring circuit may not exceed 600 V
in CAT II.
The maximum permissible Measuring >5 A must only be performed for max. 10
seconds and at 10 minute intervals.
Always start current measurements at the highest measurement range and switch
down to lower ranges if necessary. Before changing the measurement range,
always power down the circuit. All current measuring ranges are secured with fuses
and thus protected against overload.
Never measure any currents above 10 A in the 10 A range and no currents above
400 mA in the mA/
Ȟ
A range; otherwise the fuses trigger.
Proceed as follows to measure direct current “DC” (A ):
1. Switch on the DMM and select “A ”, “mA ” or “µA ”. If you are not sure about the measured
range, start with a larger range (“A ”).

2. Depending on the measuring function chosen, plug the red measuring lead into the 10A measuring
jack (20) / mAµA measuring jack (19) and the black measuring lead into the COM measuring
jack (18).
3. Now connect the two test prods in series with the object to be measured (battery, circuit, etc.); the
display indicates the polarity of the measured value together with the currently measured value.
