Testing AC Voltage Using Digital Multimeter - Electronics LAB

Multimeter: Testing AC Voltage

A.Choose active alternating current socket.

B.Turn the multimeter knob to the ACV or AC Voltage section:

To ensure safe operation make sure that the knob is pointing to 400V before connecting the probe to the plug.

Also make sure that the red probe is connected to the ‘V’ and the black probe to the COM as shown in the image given below:

C. Insert the testing probes into the socket.

Polarity is not an issue in AC.
E. Power ON the Multimeter.
F. Turn ON the AC supply.

The multimeter will display the AC voltage which is in the specified range of 220-240V, indicating the AC supply to be working normally.
