Dc ('V ") Voltage Measurement - VOLTCRAFT VC252 Operating Instructions Manual

12.3 AC ("V
1. Switch on the DMM and select "V" mode.
"DC" will show on the display.
Æ
For lower voltages up to max. 400 mV, select the "mV" measuring range.
Æ
2. Press SEL/
"AC" will show on the display.
Æ
3. Plug the red lead into the V terminal and the black lead into the COM terminal.
4. Connect the two measuring probes in parallel to the object that you want to
measure (e.g. generator or circuit).
The measurement will appear on the display.
Æ
5. After taking a measurement, remove the leads from the measured object and
switch off the DMM.
The "V/AC" range has an input resistance of ≥10 MΩ. This means that
there is almost no load on the circuit.
If "-" appears in front of a direct voltage measurement, this indicates that
the measured voltage is negative (or that the measuring probes have
been connected in reverse).
The "V DC/AC" voltage range has an input resistance of >10 MOhm; the
"mV DC" range has an input resistance of >100 MOhm.
