12.4 Measure mV/AC voltage “mV ”
Proceed as follows to measure “mV/AC” voltages:
1. Switch the DMM on and select
mV
mode. “DC” and “mV”
will appear on the display.
2. Press the
SEL
/
button on
the rotary control to switch to
“AC” mode.
Æ
“AC”, “TRMS” and “mV” will
appear on the display.
3. Insert the red lead into the
V
socket and the black lead into
the
COM
socket.
4. Connect the two measuring
probes in parallel to the object
that you want to measure (e.g.
generator or circuit).
Æ
The measurement will appear on the display.
5. After taking a measurement, remove the leads from the measured object and
switch the DMM off.
The voltage measurement range “mV/AC” has an input resistance of
≥100 MΩ. This (almost entirely) prevents a load on the circuit.
