Page 11: 4．Wire Resistance Verification
Before measuring earth ground resistance, firstly please confirm voltage to ground must be lower than 10V. Otherwise, the measurement value may cause excessive Note error. At that time, firstly cut off power on measured earthing equipment and make resistance measurement after the earthing voltage is reduced. -
