How Digital Earth Resistance Testers Work
Digital earth resistance testers use a combination of electrodes, typically two to four, to measure the resistance between the earth and the grounding system. The instrument sends a low-level current through the ground and measures the voltage drop across the system. The resistance is calculated using Ohm’s law (R = V/I), where the result indicates the grounding system’s effectiveness
