Easy Pole Clamp-On Ground Resistance Tester with Super Slim Jaw (Wireless Adapter Z3210 not included)

The FT6380-50 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.


Key Features

  • Easily transfer measurement data to your smartphone or tablet by using our free app GENNECT Cross or to an Excel® file. (Wireless Adapter Z3210 is necessary)
  • 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
  • Data can be downloaded to tablets and smartphones using Hioki’s dedicated free app "GENNECT Cross," available from the Google Play or App Store.
  • Multiple grounding can be easily checked with the clamps.


Measure multi-grounded systems

Clamp on the earth cable. The instrument has two cores for voltage injection and current measurement.

1. The voltage transducer injects a defined voltage into the multi-grounded system.

2. From the defined voltage and measured current, the total circuit loop resistance is calculated in the following equation.

Rx + 1/ [ (1/R1) + (1/R2) + (1/R3) + (1/R4) + ... ] = V/I

In a typical multi-grounded system, the parallel resistance value is small enough to be ignored and the equation as referred on the left can be simulated as follows.

Rx = V/I


Clamp at the narrowest point!

The dramatically slim 0.79 inch (20mm) jaws let you finish your job easily and efficiently.


Easily transfer measurement data to an Excel® file

Excel® Direct Input function allows you to input measurement values directly and automatically into an Excel® file once the instrument's auto-hold function is activated. (Wireless Adapter Z3210 is necessary)
