Manual
JK7305 ground resistance tester is used to measure the internal electrical equipment grounding resistance, it reflects the total grounding of electrical equipment around the exposed conducting part and electrical equipment terminal (contact resistance). Ground resistance tester in order to eliminate the effects of contact resistance test, using four terminal measurement method, namely in the measured electrical exposed between the guide part and the main earthing terminal with current voltage measurement, and then it ends, calculate the resistance value.
