A clamp meter measures the current in a wire by closing a jaw around it, so you never have to break the circuit. Most also work as a multimeter through test leads, reading voltage, resistance and continuity. These rankings cover handheld digital clamp meters for electricians, HVAC technicians and DIY work, from about $60 to $750.
AC or AC/DC is the first choice. An AC-only clamp reads household and commercial wiring. To read current on solar panels, batteries, inverters or a car’s electrical system, you need a clamp that measures DC through the jaw. Some HVAC clamps read DC microamps through the test leads for flame sensors, but that does not replace DC in the jaw.
Safety rating is the second. The CAT rating says where a meter can safely be used. CAT III covers distribution panels and building wiring; CAT IV covers the service entrance, the meter base and outdoor feeders. The higher the voltage beside the rating, the more a meter can survive a voltage spike. Buy the rating your work needs, not just the voltage.
True RMS matters on any circuit with electronics, LED drivers or variable-speed motors, where a meter without it can read well off. Inrush mode catches a motor’s starting current, LoZ mode stops ghost voltages from showing on idle wires, and a low-pass filter steadies readings on variable-speed drives.
