The basic metric unit for length is the meter (m).
An analog clamp meter operates based on the principle of electromagnetic induction. When current passes through a single conductor, it generates a magnetic field. The clamp jaw detects this magnetic field and induces a corresponding current in its internal coil. As a result, the needle on the analog scale moves in response to the strength of that induced current, allowing you to read the AC current directly without having to disconnect any wires. You can find reliable clamp meters that utilize this principle at Enrgtech.
