CAUTION
The maximum input for DC current is 10A. Do not attempt to measure
higher currents to avoid electrical shocks or damages to the instrument.
Fig. 5: Using the instrument for AC Current measurement
1. Power off the circuit under test.
2. Selecting the position
3. Press the SEL key to select AC measurement. The “ ” symbol is shown at display
4. Insert the test leads into the jacks, the red plug into A jack and black plug into COM
jack
5. Connect the red and the black plugs in series with the circuit whose current is to be
measured respecting the polarities (see Fig. 5)
6. Energize the circuit under test. The current value will be displayed
7. The message "O.L." means that the detected current exceeds the limits
8. For HOLD function and Relative measure please refer to § 4.2
