12.7 Measuring frequency
The multimeter can be used to measure the frequency of a signal voltage (supports
frequencies from 10 Hz to 10 MHz). The maximum input is 20 Vrms. This mode is
not suitable for taking measurements on mains voltages. Observe the input specifi
-
cations in the technical data.
Proceed as follows to take a frequency measurement:
1. Switch on the DMM and select
mV
mode.
2. Press
SEL
/
to switch to “Hz”
mode.“Hz” will appear on the display.
3. Plug the red lead into the
Hz
termi-
nal and the black lead into the
COM
terminal.
4. Connect the two measuring probes to
the object that you want to measure
(e.g. signal generator or circuit).
Æ
The frequency and correspond-
ing unit will be displayed.
5. After taking a measurement, remove
the leads from the measured object
and switch off the DMM.
