12.3 Measure AC voltage “V ”
Proceed as follows to measure “V/AC” voltages:
1. Switch the DMM on and select
the
V
measurement mode.
“AC” and “V” will appear on the
display.
Æ
For lower voltages up to
max. 600 mV, select the
mV
measurement range.
2. Insert the red lead into the
V
socket and the black lead into
the
COM
socket.
3. Connect the two measuring
probes in parallel to the object
that you want to measure (e.g.
generator or circuit).
Æ
The measurement will ap-
pear on the display.
4. After taking a measurement, remove the leads from the measured object and
switch the DMM off.
The voltage measurement range “V/AC” has an input resistance of ≥10 MΩ.
This (almost entirely) prevents a load on the circuit.
