  The AN9611X(F) series Ground Resistance Analyzer is a high performance instrument used in grounding resistance testing of electrical products, suitable for applications requiring large current. For example, according to section 9.11 of GB14711-2013 “General requirements for safety of small and medium size rotating electrical machines”: “The ground resistance shall be not more than 0.1 ohm and the resistance is determined as follows: apply a current equal to the full rated input or output of the motor between the grounded component and the grounded conductor terminal, measure the voltage drop and divide the voltage drop by the current flowing through the line to calculate the ground resistance." According to section 9.10, the rated motor current reaches up to 1000A. AN9611X series has excellent performance, rich features and external interfaces to meet the motor safety test requirements, applied to grounding resistance test of household electrical appliances, power tools, electrical distribution equipment, medical electrical equipment, audio-visual equipment and other AC power supply electrical equipment.
