Buying Guide

True RMS for accurate readings

Choose a clamp meter with True RMS when measuring non-sinusoidal or distorted waveforms to ensure accurate voltage and current readings on modern loads

Clamp size and jaw design

Confirm the clamp or D-jaw opening fits the conductors you work with—larger jaws handle multi-conductor bundles or insulated cables better

AC vs AC/DC capability

If you need to test automotive or DC-powered equipment, pick meters that explicitly support both AC and DC current measurements

Inrush and high-current ranges

For motor startup and large loads, look for inrush measurement or high-amp ranges (hundreds to 1000A) to capture transient and heavy-load currents

Safety and diagnostic features

Prioritize meters with safety ratings, non-contact voltage detection, and built-in tests like GFCI or continuity to speed common troubleshooting tasks
