Digital AC Clamp Meter for Electrical Diagnostics

The Rigid Industries 61-737 is a CAT III 600 V rated clamp multimeter designed for electricians and technicians measuring live circuits up to 400 A AC and 600 V AC/DC. It combines true RMS sensing with non-contact voltage alerts, diode testing and a K-type thermocouple for temperature readings.

Sustained Field Use with Safety Indicators

True RMS architecture maintains accuracy on non-linear signals during extended troubleshooting sessions. Audible and visual non-contact voltage warnings trigger from 40 V to 600 V, while the backlit display and built-in probe holder support one-handed operation in dim panels or tight enclosures.

CAT III 600 V Rating Determines Safe Application

The safety category and voltage rating define the installation environments this meter can enter. Buyers needing measurement on higher-energy distribution gear or circuits above 600 V must select a differently rated instrument.

Questions about this item

How much heat or noise does the 61-737 produce when measuring 400A AC continuously?

The clamp meter is a battery-powered handheld tool with no fan or moving parts, so it generates negligible heat and operates silently during extended use.

What must I already own for the 61-737 to function out of the box?

Nothing extra is required; the kit includes AAA batteries, test leads, a K-Type thermocouple and a storage pouch with belt loop.

Will the 61-737 work safely alongside older CAT III 480V equipment I still use?

Yes, its CAT III 600V rating covers the 480V environment, and the non-contact voltage alert triggers from 40V to 600V for added protection.
