A clamp meter is an electrical measuring instrument used to measure current flowing through a conductor without needing to make direct contact with the electrical circuit. It works by clamping around a wire or cable, utilizing the magnetic field produced by the current to determine its strength.
Clamp meters can measure both AC (alternating current) and DC (direct current) and often include additional features like voltage measurement, resistance measurement, and continuity testing. They are commonly used by electricians and technicians for troubleshooting and maintaining electrical systems.
