Note: Make sure that the socket is not turned ON.

Step 2: 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:

Polarity is not an issue in AC.

Step 4: TURN ON THE POWER SUPPLY.

Step 5 :Power ON the Multimeter.

Step 6: Turn ON the AC supply.
