Q. Are a tong tester and a clamp meter the same thing?

Answer

Yes, both are the same device. Tong Tester is another name for a clamp meter. For measuring a live conductor without disrupting or shutting off the circuit, this simple-to-operate testing device is invaluable. It picks up the current's magnetic field as it flows through the wire. Using it, release or secure the clamps. Its purpose is to illuminate the LCD screen so that the displayed value may be read in low light conditions or at night. It plugs into the meter cable's negative (ground) jack. It plugs into the meter's positive jack. There is a readout of the value being monitored. It determines the kind and measuring range of current.
