The Fluke 323 True RMS clamp meter is a rugged, reliable basic troubleshooting tool designed for commercial and residential electricians. It delivers accurate, noise-free measurements in the toughest environments, allowing users to confidently diagnose problems.

The meter measures AC current up to 400A, AC and DC voltage up to 600V, and resistance up to 4kΩ with continuity detection. True RMS AC voltage and current provide accurate readings on non-linear signals such as those produced by variable frequency drives and compact fluorescent lighting. The continuity buzzer sounds for resistance below 70Ω.

The slim, ergonomic design allows easy access to tight cable compartments, and the large, easy-to-read display presents measurements clearly. A Data Hold function captures readings on the screen for later reference.

Safety features include CAT IV 300V and CAT III 600V ratings, meeting IEC 61010-2-032 standards. The meter operates on two AAA batteries and weighs only 265g. It comes with test leads, a soft carrying case, and a two-year warranty.

Applications include verifying load current, checking AC voltage presence, and testing continuity of circuits, switches, fuses, and contacts.
