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 :
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
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)
