The Fluke 368 true-rms leakage current clamp meter helps users detect, document, record and compare leakage current readings over time as a means of preventing unplanned downtime, and identifying intermittent GFCI and RCD trips, all without taking equipment off line.

The Fluke 368 has a large 40 mm diameter jaw for work with large conductors. The clamp’s jaw is fully shielded to accurately capture very small leakage signals, and to minimize external electromagnetic interference.
