How does the multimeter distinguish between the zero line and the live line
Generally speaking, to identify the neutral and live wires in the mains, you must use a low-voltage tester. Can a multimeter distinguish the live and neutral wires?
The answer is yes, the method is as follows:
Turn the range switch of the multimeter to AC voltage 250V or 500V. The black test lead is connected to the plumber in the room, the wet ground, land, etc., and the red test lead is in contact with the power line or the power socket hole. The higher voltage value indicated by the multimeter is the live wire. The voltage value is low or zero is the zero line.
