Electricians increasingly utilize multimeters instead of electric pens for maintenance and troubleshooting. In reality, many individuals are unaware that the multimeter can also tell a live wire from a neutral wire in addition to the electric pen, which may make this distinction.
The method of distinguishing live wire and zero wire by electric pen
Ordinary electric pen: In the past, a single electric pen was utilized globally for maintaining and repairing electrical systems. The live wire and the neutral wire can be distinguished with a standard electric pen. The neutral wire is what lights up the electric pen, not the live wire.
Digital electric pens: Because they are readily available, regular electric pens are rarely utilized. For digital electric pens, it performs additional tasks such determining whether a wire is shorted-circuited, separating live from neutral wires, and identifying the positive and negative poles of DC batteries. It's okay, since the standard electric pen is progressively phased out. You can immediately use the electric pen to measure the live wire and the neutral wire, and then watch the voltage of the digital electric pen, if you use a digital electric pen to tell the live wire from the neutral wire.
The primary purpose of the inductive breakpoint measuring pen is to locate the breakpoint inside the line when the wire is not electrified. The sound of the electric pen measuring the live wire is quite quick, whereas the sound of the electric pen measuring the neutral wire is rather slow.
