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)
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
