4.3.2. AC Voltage measurement
CAUTION
The maximum input AC voltage is 600V. Do not measure voltages
exceeding the limits given in this manual. Exceeding voltage limits could
result in electrical shocks to the user and damage to the instrument.
Fig. 3: Use of the instrument for AC voltage measurement
1. Select position V Hz% . The symbol
“
AC
”
is shown on the display.
2. Insert the red cable into input terminal Hz%V

and the black cable into input
terminal COM .
3. Position the test leads in the desired spots of the circuit to be measured (see Fig. 3).
The display shows the value of voltage.
4. The message
“
O.L.
”
indicates that the value of AC voltage exceeds the maximum
measurable value.
5. Press the Hz% key until symbols
“
Hz
”
or
“
%
”
are shown in order to activate the display
of frequency and duty cycle associated to the value of AC voltage.
6. To use the HOLD function and Relative measurement, see § 4.2
