Fluke 369 User Manual

Introduction
The 368/369 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.
