What is a clamp meter and how does it work?
A clamp meter, also known as a current clamp or amp clamp, is an electrical testing device used to measure current flow without the need for direct contact. It works by clamping around a conductor, utilizing the principle of electromagnetic induction to detect the current passing through the conductor.
Why are clamp meters essential for electrical testing?
Clamp meters provide a safe and convenient way to measure electrical current without interrupting the circuit. They eliminate the need for direct contact with live wires, ensuring the safety of the user. Additionally, clamp meters offer multifunctionality, allowing users to perform various tests such as voltage measurement, resistance measurement, continuity testing, and frequency measurement.
