How to use a Clamp Meter

What is a clamp meter?

A clamp meter is an electrical test tool that combines a basic digital multimeter with a current sensor. It is a clothespin-shaped instrument that can be clamped around a live wire in order to measure the current it’s carrying. The typical multimeter has to be inserted in series with the circuit under measurement, requiring that it be cut first. By contrast, clamp meters can measure the current flowing in the wire around which they’ve been clamped by detecting the magnetic field generated by the current.

Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable or other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/deenergizing it.

Beneath their plastic moldings, hard jaws consist of ferrite iron and are engineered to detect, concentrate and measure the magnetic field being generated by current as it flows through a conductor.

Clamp meters are popular tools primarily for two reasons:

• Safety. Clamp meters allow electricians to bypass the old-school method of cutting into a wire and inserting a meter’s test leads into the circuit to take an in-line current measurement. The jaws of a clamp meter do not need to touch a conductor during a measurement.

• Convenience. During a measurement, it is not necessary to shut off the circuit carrying current—a big boost in efficiency.
