For L (live cable)
Turn the digital multimeter to 750 VAC, use your one hand to hold the metal end, and then the other
hand inserts the pen to the L port of the socket. See the following figure. If the multimeter shows 125,
then you can see current live cable connection is standard. If the value is less than 60, then you can
know current live cable connection is not proper or it is not the live cable at all.

Turn the digital multimeter to 750 VAC, use your one hand to hold the metal end, and then the other
hand inserts the pen to the N port of the socket. See the following figure. If the multimeter shows 0,
then you can see current N cable connection is standard. If the value is more than 10, then you can see
there is inductive current and the neutral cable connection is not proper. If the value is 120, then you
can know that you have misconnected the neutral cable to the live cable.
