WHAT IS A CLAMP METER?

A clamp meter is a specialized electrical testing instrument that combines a digital multimeter with a current transformer, allowing technicians to measure electrical current without breaking the circuit. Unlike traditional multimeters that require interrupting the circuit to measure current, clamp meters feature jaws that open and close around conductors, making them safer and more convenient for electrical testing.

Clamp meters work through electromagnetic induction, where current flowing through a conductor creates a magnetic field that the meter’s jaws detect and quantify. This non-invasive measurement technique makes clamp meters essential for troubleshooting live circuits, especially in industrial and commercial settings where power interruption isn’t feasible.

Modern clamp meters typically offer additional functionality beyond current measurement, including voltage testing, resistance, continuity, capacitance, and frequency. Advanced models may include True RMS technology for accurate readings on non-linear loads, temperature probes for HVACR applications, and wireless connectivity for remote monitoring and data logging, making them comprehensive diagnostic tools for electrical professionals.
