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.

True-rms measurements for accuracy when measuring complex, non-sinusoidal waveforms
40 mm jaw opening
Highest resolution of 1 μA, measure up to 60 A
Selectable filter function removes unwanted noise
Max/Min/Average readings and hold function
Forward-facing LED worklight for use in dark wiring cabinets
Backlit display; auto backlight off and auto power off for extended battery life
CAT III 600V safety rating
