Use a multimeter to confirm the continuity and quality of the ground connection. To ensure an accurate reading, it is important that the multimeter is properly calibrated and that the probes are placed on clean, bare metal. Here’s a basic guide on how to measure ground resistance and test the grounding system’s proper functionality using a multimeter: Methods of testing soil resistivity and ground resistance. Another method of calculating the resistance of a single ground rod, when the dimensions and the resistivity are known is using nomograms. A multimeter can be used to measure the resistance of a ground by placing the probes on either side of the ground rod. Each has its own characteristics. High resistance readings suggest there is a fault that needs attention. Accurate ground resistance measurements help identify and address any potential issues, such as inadequate grounding or high soil resistivity, which can affect the overall performance of electrical systems. Clamp a ground meter around the grounding electrode conductor and turn it on.
