 The Changzhou LandTek LK2678, the 2678B ground resistance tester LK Series Ground Resistance Tester is used to measure the electrical equipment for internal grounding resistance, it reflects the total between the ground terminal of electrical equipment around the exposed part of the electrical equipment can guide (contact) resistance. Ground Resistance Tester in order to eliminate contact resistance test, the use of four-terminal measurement method, plus the current between the exposed conduction part of the measured electrical and ground terminal, and then measuring the voltage across the calculate its resistance value
