Fluke 368 User Manual

Introduction
The 368/368 FC and 369/369 FC AC Leakage Current Clamp (the Product) is a handheld tool for
measurement of ac leakage current.
Principle of Leakage Current Measurement
Based on the electromagnetic induction principle, the Product has a ring-shape current transformer
comprised of a metal core and coil winding. The current transformer senses the magnetic field produced
by the current or by the vector sum of the currents flowing in the conductor under test. The current
transformer then produces a current proportional to the current flowing in the conductor.
See the Product Functions section near the end of this manual.
