Hioki FT6380 Clamp On Earth

Detail Hioki Clamp On Earth FT6380 :

The FT6380 measures 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 ires with ease, and also provide AC currennt measurement functionality and can measure currents ranging from leakaage current on the other of ceveral mA to load currents of up to 60 A.

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

Specifications :

  • Measurement principle : Instrument has two cores for voltage injection and current measurement.. From the defined voltage and measure current, the total circuit loop resitance 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 resitance : 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 : N/A
  • 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)
