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. | |||||
