4.4.2. AC Voltage measurement
CAUTION
The maximum input AC voltage is 1000V. 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. 23: Use of the instrument for AC voltage measurement
1. Select positions V
Hz% or mV
2. In position mV
, press the F2 (MODE) key to view symbol
“
”
on the display.
3. Insert the red cable into input terminal VHz%CAPTemp
and the black cable into
input terminal COM.
4. Position the red lead and the black lead respectively in the spots of the circuit to be
measured (see Fig. 23). The display shows the value of voltage.
5. If the display shows the message "O.L", select a higher range.
6. Press the F2 (MODE) key to select measurements
“
Hz
”
or
“
%
”
in order to display the
values of frequency and duty cycle of input voltage. Press the F1(TRIG) key to select
the positive or negative half-wave of the function “%”The bargraph is not active in these
functions.
7. To use the HOLD, RANGE and REL function, see § 4.2.
8. To use the internal functions, see § 4.3.
