CAUTION
The maximum input for AC voltage is 750Vrms. Do not attempt to measure
higher voltages to avoid electrical shocks or damages to the instrument.
Fig. 3: Using the instrument for AC Voltage measurement
1. Selecting the position
2. Pressing the R/SEL key to select the correct range or using the Autorange feature (see
§ 4.2). If the voltage value under test is unknown, select the highest range
3. Insert the test leads into the jacks, the red plug into V Hz
A jack and black plug
into COM jack
4. Connect the test leads to the circuit under test (see Fig. 3). The voltage value is
displayed
5. If the message " O.L " is displayed select a higher range
6. For HOLD function, Minimum and Maximum value measurement and Peak
measurement please refer to § 4.2
