Technical Specifications

Measurement principal  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.
