How a Multimeter Detects Live or Neutral
For the method of judging whether the multimeter is live or neutral, using the test range of the multimeter, you can accurately determine which is the live wire and the neutral wire. For those who do not know, you can refer to the method provided in this article.

Multimeter to judge live wire or neutral wire
Set the test range of the multimeter to the highest range of the AC range (1000 or 500, etc.) or higher than the voltage to be tested, on the low-voltage power distribution cabinet in the equipment room, on the power distribution box at home or on the wiring bar, assuming that one end is For the live wire, one test lead is inserted into the hypothetical end, and the other test lead is inserted into the other two jacks or terminals respectively. Say phase line L;
As for the zero line, it's not very discriminating.

If there must be a result, while you live on the live wire, the remaining two points are either the ground or the neutral wire (nonsense, sometimes not necessarily), then connect the test lead to one of the two terminals, and the other test lead Connect to the ground, if the voltage is displayed, it is the zero line, that is, N, otherwise it is the ground line G.
