Dc/Ac Voltage Measurement - VOLTCRAFT VC272 Bedienungsanleitung

12.3 DC/AC voltage Measurement

1. Set the function dial to the required setting.
2. "DC" will show on the display.
Short press the SEL/
Æ
button to switch to AC,
"AC" will show on the dis-
play.
For lower voltages up to
Æ
max. 600 mV, select the
mV measuring range.
3. Connect the test leads to the
terminals:
Red test lead to the
Æ
terminal.
Black test lead to the COM
Æ
terminal.
4. Connect the two measuring probes in parallel to the object that you want to
measure (e.g. generator or circuit).
The measured value will appear on the display.

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.
DC voltage measurements (V ): If a minus "-" sign appears in front of
the value, the measured voltage is negative (or the measuring lines are
swapped).
The "V DC/AC" voltage range has an input resistance of >10 MOhm; the
"mV DC" range has an input resistance of >100 MOhm.
