c) Voltage measurement “V”
Proceed as follows to measure direct voltages “V ”(DC):
- Switch the DMM on and select the “V
” measurement
mode. “DC” and “V” will appear on the display.
- For lower voltages up to max. 600 mV, select the “mV
”
measurement function.
- Insert the red lead into the V socket (G) and the black lead into
the COM socket (H).
- Connect the two measuring probes to the object to be meas-
ured (battery, switch, etc.). Connect the red measuring probe
to the positive terminal and the black measuring probe to the
negative terminal.
- The polarity of the measurement is indicated on the display.
- After taking a measurement, remove the leads from the meas-
ured object and switch the DMM off.
If “-” appears in front of a direct voltage measurement, this indicates that the measured voltage is negative
(or that the test leads have been connected in reverse).
The “V DC/AC” voltage range has an input resistance of >10 MΩ. The mV range has an input resistance of
≤1000 MΩ. If open measuring inputs are used, an undefined measurement value may be displayed in the
mV range due to the high input resistance. This, however, has no effect on the measurement result.
