Hioki Digital Clamp Earth Tester, FT6380, 600V

The FT6380 measures grounding resistance simply by clamping to multiple-grounded ground wires. No auxiliary grounding rod is needed, and there is no need to disconnect the ground wire from the grounding rod. The compact, low-profile sensor can be used to clamp ground wires with ease, and also provide AC current measurement functionality and can measure currents ranging from leakage current on the order of several mA to load currents of up to 60 A.

• Earth resistance measurement for multi-grounded systems
• Measure leak current with absolute certainty with highly sensitive 0.01 mA resolution (at 20.00 mA range)
• Measure load current up to 60.0 A range
• Clamp at the narrowest point
• Other functions: Data hold, Backlight, Filter, Auto power save
• Memory function: 2000 data
• Max. allowable input: 100 A AC continuous, AC 200 A for 2 minutes or shorter (at 50/60 Hz, requires derating at frequency)
