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
