| Hioki FT6380-90 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. |
