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.

Basic Specifications
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.
Earthing resistance range
0.20 Ω (0.01 Ω resolution) to 1600 Ω (20 Ω resolution), 10 ranges, Zero suppression: Less than 0.02 Ω,
Accuracy: ±1.5 % rdg. ±0.02 Ω
AC Current range
20.00 mA (0.01 mA resolution) to 60.0 A (0.1 A resolution), 5 ranges, Zero suppression: Less than 0.05 mA,
Accuracy: ±2.0 % rdg. ±0.05 mA (30 Hz to 400 Hz, True RMS), Crest factor 5.0 or less (for the 60 A range, 1.7 or less)
Maximum input current (Current measurement)
100 A AC continuous, AC 200 A for 2 minutes or shorter (at 50 Hz/60 Hz, requires derating at frequency)
Maximum rated terminal-to-ground voltage
600 VAC measurement category IV (anticipated transient overvoltage 8000 V)
Memory function
2000 data
Alarm function
For resistance measurement and current measurement, Beeps when measured value is less than or greater than threshold.
Other functions
Data hold, Backlight, Filter, Auto power save, Wireless communication (without Z3210 installed))
