1.1 Product Overview
The FT6380 and FT6381 Clamp On Earth Tester make ground-
ing resistance measurements simply by being clamped to multi-
ple-grounded ground wires. No auxiliary grounding rod is
needed, and there is no need to disconnect the ground wire from
the grounding rod.
The instruments also provide AC current measurement function-
ality and can measure currents ranging from leakage current on
the order of several mA to load currents of up to 60 A.
The FT6381 emits radio radiation. Because use of devices that
emit radio radiation requires approval in the country of use, be
careful that use of the instrument in a country or region other
than those listed on the attached cautionary leaflet, "Precautions
Concerning Use of Equipment That Emits Radio Waves" or the
HIOKI products website may be subject to penalty as a violation
of law.
