The 2301 is a big breakthrough of traditional grounding resistance measurement technology, and is used for measuring the grounding resistance of the system with circuits, for example, the grounding resistance of power transmission lines or the grounding resistance of communication lines. Auxiliary grounding rods are not needed to use when measuring, several parallel connected grounding system can be applied, and the equipment to be tested are not interrupted. The grounding resistamce can be safety and quickly measured by champing the grounding wires or the grounding rods only with the jaws.
