How to use a digital multimeter to distinguish whether the power line is live or neutral
the first method:
The above method can be used to judge: the larger number is the live line, and the smaller number is the zero line. This method requires contact with the line or device being measured.
The second method:
No contact with the line or device being measured is required. Turn the multimeter to AC2V block, the black test pen is hanging in the air, hold the red test pen and gently slide the pen tip along the line, if the meter shows a few volts at this time, it means that the line is the live wire. If the display is only a few tenths of a volt or even less. It means that the line is the zero line. This judgment method does not directly contact the line. Not only safe but also convenient and fast.
