Key Features • Compatible with Hioki common free App GENNECT Cross (Optional Wireless Adapter Z3210 is necessary) • Wirelessly transfer measurement data to Excel forms for input (Will be supported by the 2021 upgrade) • 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
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) Dust-proof and waterproof IP40 (EN60529) With Jaws Closed Approx. 35 hours (25 Ω measurement, backlight off, with Z3210 installed and using wireless communications) Maximum measurable conductor diameter 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)
