4.4.2. AC Voltage and Frequency measurement
CAUTION
The maximum input AC voltage is 1000Vrms. 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 positions V
or mV
2. If necessary, press the MODE key for manually selecting AC measurement (see §
4.3.3) or HFR measurement (see § 4.3.4).
3. Use the RANGE key for manually selecting the measuring range (see § 4.2.6) or use
Autorange selection. If voltage value is unknown, select the highest range.
4. Insert the red cable into input lead Hz°CV
 and the black cable into input lead COM
5. Position the red lead and the black lead respectively in the points of the circuit to be
measured (see Fig. 3). The display shows the value of voltage.
6. If the display shows the message “OL”, select a higher range.
7. Press the Hz/
0 key to display the frequency measure of AC voltage. The symbol
“Hz” is shown on the display.
8. For using the HOLD function, see § 4.2.1, for measuring MAX/MIN/AVG values see §
4.2.2 and for saving the result, see § 4.2.5
