easurement Principle The 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 © ( 0.01 © resolution) to 1600 © ( 20 © resolution) , 10 ranges, Zero suppression: Less than 0.02 © , Accuracy: ± 1.5 % rdg. ± 0.02 © 
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 and under ( 1.7 and under at 60 A range) 
Max. allowable input AC 100 A continuous, AC 200 A for 2 minutes or shorter ( at 50/ 60 Hz, requires derating at frequency) 
Max. rated voltage to earth AC 600 V CAT IV
