Voltage measuring
The maximum permissible voltage in the measuring circuit may not exceed 600 V
in CAT II.
Proceed as follows to measure direct voltages “DC” (V ):
1. Switch on the DMM and select measuring function “V
”. The indication “DC” shows on the
display.
2. Plug the red measuring lead into the VΩ Hz measuring jack (10) and the black measuring
lead into the COM measuring jack (11).
3. Now connect the two measuring leads to the object to be measured (battery, circuit, etc.). The red
measuring lead is the positive pole, the black measuring lead is the negative pole.
4. The polarity of the respective measured value is indicated on the display together with the current
measured value.
If a minus “–” appears in front of the measured value for direct voltage, the measured voltage is
negative (or the measuring leads are swapped). The voltage range “V DC/AC” shows an input
impedance of >10 MΩ.
5. After measuring, remove the measuring leads from the measured object and turn off the DMM.
Proceed as follows to measure alternating voltages “AC” (V~):
1. Switch on the DMM and select measuring function “V
”. Press the shift button (8) to switch to
“V~”.The indication “AC” and “TrueRMS” show on the display.
2. Plug the red measuring lead into the VΩ Hz measuring jack (10) and the black measuring
lead into the COM measuring jack (11).
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.
