Ground Clamp with Unsurpassed Repeatability - Clamp On Earth Tester FT6380/FT6381 | HIOKI
| Basic specifications (Accuracy guaranteed for 1 year, or opening and closing of the clamp sensor 10,000 times) |  |
| Measurement Principle | The 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 and under (1.7 and under at 60 A range) | | Max. allowable input | AC 100 A continuous, AC 200 A for 2 minutes or shorter (at 50/60 Hz, requires derating at frequency) | | Max. rated voltage to earth | AC 600 V 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, Back light, Filter, Auto power off | | Display | Digital LCD, max. 2000 dgt., Display refresh rate: 500 msec (approx. 2 times/second) | | Waterproof and dustproof | IP40 (EN60529: 1991+A1: 2000) 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 batteries ×2, Max. rated power: 450 mVA, Continuous use : 35 hr (in-house testing conditions) | | Core jaw dia. | φ 32 mm (1.26 in) | | Dimensions, mass | 73 mm (2.87 in) W × 218 mm (8.58 in) H × 43 mm (1.69 in) D, 620 g (21.9 oz) | | Supplied accessories | Carrying case ×1, Resistance check loop ×1, Strap ×1, LR06 alkaline battery ×2, Instruction manual ×1 |
