Measuring AC Current

1. Turn off power to the circuit. Discharge all high-voltage

capacitors.

2. Turn on the meter, then set up the meter to measure AC current

as shown in Figure 9.

3. Insert the black test lead into the COM terminal and the red lead

in an input appropriate for the measurement range as shown in

Table 6.

4. Connect the test leads to the circuit under test so the meter is in

series with the circuit.

5. Set the meter to AC mode by pressing the SELECT button

(then, “AUTO” “AC” and “μA”, “mA”, or “A” symbols are indicated

on the display).

6. Turn on the power to the circuit under test.
