What is a Clamp Meter?
A clamp meter, also known as a clamp-on ammeter or tong tester, is an electrical test instrument that combines a basic digital multimeter with a current sensor. It is designed to measure electrical current flowing through a conductor without the need to disconnect the circuit or make physical contact with the conductor itself.
The clamp meter works by clamping its jaws around the conductor through which the current is flowing. The jaws contain a sensor that detects the magnetic field generated by the current. Based on this magnetic field, the clamp meter can measure the current passing... Read More
