The HIOKI FT6380-90 Ground Resistance Clamp provides accurate, non-disconnecting ground resistance measurements for multi-grounded electrical systems. Featuring a dual-coil clamp design, this instrument measures ground resistance from 0.02Ω to 1600Ω across 10 automatically selected ranges, while accommodating conductor diameters up to 32mm. The integrated Bluetooth adapter enables wireless data transfer to smartphones, tablets, and computers for comprehensive documentation and reporting.

Designed for utility professionals, this CAT IV 600V rated instrument also measures AC current up to 60A and leakage current starting from 20mA using True RMS measurement. Key operational features include configurable threshold alarms, internal memory for 2000 readings, switchable backlight, and HOLD function. The device operates on standard AA batteries providing approximately 35-40 hours of operation, and includes GENNECT Cross app compatibility for enhanced data management and field documentation.
