e) Voltage Measuring “mV”
There is a dedicated measuring function to measure smaller voltages up to 600 mV at a high resolution. This function
can be used for alternating and direct voltage alike.
Proceed as follows to measure alternating voltages “AC “ (mV ):
- Turn the DMM on and select measuring function “mV ”.
Thedisplayshows“AC”andtheunit“mV”.
- Plug the red measuring line into the V measuring jack (E)
and the black measuring line into the COM measuring
jack (D).
- Connect the two measuring prods to the object to be
measured in parallel (generator, circuit, etc.).
- The measured value is indicated on the display.
- Remove the measuring lines from the object to be meas-
ured after completion of the measurement and switch off
the DMM.
 Thevoltagerange“mV”hasaninputresistance
of≥10MΩ.Withthemeasuringinputsopen,the
highsensitivitymaycauseanundenedmeas-
ured value to be displayed; however, this does
notinuencethemeasuringresult.
Proceed as follows to measure direct voltages “DC” (mV ):
- Turn the DMM on and select measuring function “mV ”.
- Press“SELECT”toswitchtothedirectcurrentmeasurementrange.The
displayshows“DC”andtheunit“mV”.
- Plug the red measuring line into the V measuring jack (E) and the black
measuring line into the COM measuring jack (D).
- Connect the two measuring prods to the object to be measured in paral-
lel (generator, circuit, etc.). The red measuring prod indicates the positive
pole, the black measuring prod the negative pole.
- The polarity of the respective measured value is indicated on the display together with the current measured value.
- Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the DMM.

(or the measuring lines are swapped).
