■ LKThe series grounding resistance tester is used to measure the grounding resistance inside electrical equipment, which reflects the exposed conductive properties of the equipment

partThe (contact) resistance between the main grounding terminal of electrical equipment. In order to eliminate the influence of contact resistance on the test, the grounding resistance tester adopts

Use four terminal testingMeasurement method, which involves adding current between the exposed conductive part of the tested electrical device and the main grounding terminal, and then measuring the voltage at these two ends

Determine its resistance value.
