CLAMP ON EARTH TESTER

FT6381

Lightweight Ground Resistance Tester with Bluetooth® Data Transfer

The FT6381 measure 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 600V Key Features • 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 transfer to Android™ phones using Bluetooth® wireless technology (FT6381) • Real time data transfer, automatic report generation on Android™ phone (FT6381)

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)

Measurement principleInstrument 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 resistance0.20 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 measurement20.00 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)
Max. allowable input100 A AC continuous, AC 200 A for 2 minutes or shorter (at 50/60 Hz, requires derating at frequency)
