The FT6380-90 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. CAT IV 600 V.

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

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

The new FT6380-90 is compatible with the Z3210 wireless adapter (option). When the Z3210 is installed, Bluetooth wireless communication is enabled. The measurement data can be transferred to the dedicated free application GENNECT Cross or your Excel® files and reports.

Open an Excel® file and select a cell. The measured value being held on the instrument’s display will be transferred to the PC and entered into the selected cell. *Optional Wireless Adapter Z3210 is necessary.

GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports. The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos. In the previous model FT6381, only Android was supported in a separate app, but the new model supports GENNECT Cross, allowing users to create reports together with measurements from other instruments. *Optional Wireless Adapter Z3210 is necessary.

Set the alarm to audibly and visually notify yourself that the resistance or current value exceeds the threshold.

Well-designed magnetic shields eliminate the leakage flux between the two cores that often affect measurement accuracy.

With the bright back light, you can easily read the measurement value even in dark locations.

You can store up to 2,000 measurement values in the field and recall them in your office later.
