CLAMP ON EARTH TESTER FT6380, FT6381
• 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
• Real time data transfer, automatic report generation on Android™ phone
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 | 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 measurement | 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) |
Max. rated voltage to earth | 600 V AC CAT IV |
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 |
Display | Digital LCD, max. 2000 dgt., Display refresh rate: 500 ms (2 times/s) |
Waterproof and dustproof | IP40 (EN60529) with clamp sensor closed |
Communication interface | Model FT6381 only: Bluetooth® v2.1+EDR, Compatibility for Smartphone / Tablet, Displays measured values on the screen of an Android™ handset via Bluetooth®, Applicable OS: Android™ 2.1 or later |
Power supply | LR6 (AA) alkaline battery ×2, Max. rated power: 450 mVA, Continuous use : 35 hr (in-house testing conditions) |
Core jaw dia. | φ 32 mm (1.26 in) |
Dimensions and mass | 73 mm (2.87 in) W × 218 mm (8.58 in) H × 43 mm (1.69 in) D, 620 g (21.9 oz) |
