Grounding is increasingly important for the safe operation and maintenance of communications equipment and many other types of facilities. However, in an urban environment where the ground is covered with concrete or asphalt, conventional measurement methods that require inserting auxiliary grounding electrodes are difficult to use. The 3143 uses a new measurement principle that makes auxiliary grounding electrodes unnecessary, so it can be used to measure ground resistance on paved roads.
