HIOKI-FT6380 CLAMP ON EARTH TESTER

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 calculatedNote: 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)


Max. allowable input
100 A AC continuous, AC 200 A for 2 minutes or shorter (at 50/60 Hz, requires derating at frequency)
