Hz: DC/AC VOLTAGE AND FREQUENCY MEASUREMENT (M73 AND M75)
CAUTION
The maximum input voltage is 550+10%V. Don’t try to measure higher
voltages to avoid risks of electrical shocks or serious damages to the
instrument.

Hz test
1.
Turn on the instrument
2.
Press the arrow keys to select
V
Hz
3.
Insert the black and green cables in the corresponding input terminals of the
instrument
4. If necessary, insert the croco clips on the test probes
5. Connect the cables to the desired points of the circuit under test as shown in Fig. 2. The
voltage and frequency values will be displayed with automatic range selection.
6. The instrument automatically switches from AC to DC voltage basing on the signal applied
to terminals.

AC voltage value
Example of display of AC voltage and
frequency values. The minimum reading
limit of AC voltage is 0.5V. Lower input
values are displayed as 0.0V.
