f) 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 voltage measured value is displayed in the main dis-
play and the frequency in the small subdisplay.
- 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

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 parallel
(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.
 Ifaminus“-”appearsinfrontofthemeasuredvaluefordirectvoltage,themeasuredvoltageisnegative
(or the measuring lines are swapped).
