The new Hioki FT6380 and Hioki FT6381 are precision earth resistance measurement clamp-on testers.
Precise voltage is injected and by means of current measurement, earth resistance is computed and displayed.
The Hioki FT6381 is the Bluetooth compatible version providing automatic report generation via Android phone including date, time, measurement value and GPS-location. Up to 2000 data points can be stored internally for later downloading.
The dual slim jaws clamp up to 32 mm diameter conductors.
Maximum rated voltage is 600 volts to earth, and the instrument meets EN 61010 safety standards.
Magnetic interference is 10 mA or less in an external magnetic field of 400 A/m at 50/60 Hz AC.
