Fluke 368-FC Specifications

TECHNICAL DATA

Fluke 368/368 FC and 369/369 FC
Leakage Current Clamp Meters

Measure leakage current to track small problems,
avoid large problems

The Fluke 360 Series of true-rms leakage current clamp meters
help 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, without taking
equipment off line.

The Fluke 368 FC and 369 FC have large diameter jaws (40 mm
for the 368 FC, 61 mm for the 369 FC) for work with larger conduc­tors. The clamp’s jaw is fully shielded to accurately capture very
small leakage signals, and to minimize external electromagnetic
interference.

The 368 FC and 369 FC also offer wireless data connectivity via
Fluke Connect. As part of Fluke Connect—the industry’s largest
system of software and more than 40 wireless test tools—the
368FC and 369 FC allow you to track changes in leakage current
over time, helping to identify potential problems before they turn
into major failures.
