A clamp multimeter is composed of a current transformer and a multimeter. The core of the current transformer can open when the clamp is squeezed; the wire carrying the current to be measured can pass through the opening of the core without being cut. When the clamp is released, the core closes. A clamp multimeter … Read more
The multimeter distinguishes between live and neutral wires. Pointer Multimeter Distinguishes Live and Neutral Wires (1) Contact Measurement Method Set the multimeter switch to AC 250V or 500V. Connect the first probe to one end of the power supply and the second probe to ground (for example, on a water pipe, radiator, or damp ground). … Read more
