HIOKI CLAMP ON EARTH TESTER FT6380-50
Brand: HIOKI
Category: Digital Meters

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.

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 FT6380-50 is compatible with the Wireless Adapter Z3210 (optional).
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.

Measurement principle Instrument has two cores for voltage injection and current measurement. From the defined voltage and measured current, the total circuit loop resistance is calculated
Note: For multi grounded systems only. In a multi-grounded system, the larger the number of grounding poles, the more accurate the measured value.
