  • 4 Important Methods of Ground Resistance Testing

    2-Point (Dead Earth) Method3-Point (Fall-Of-Potential) Method4-Point MethodClamp-On MethodIn areas where driving ground rods may be impractical, the two-point method can be used.With this method, the resistance of two electrodes in a series is measured by connecting the P1 and C1 terminals to the ground electrode under test; P2 and C2 connect to a separate all-metallic grounding point (like a water pipe or building steel).The dead earth method is the simplest way to obtain a ground resistance reading but is not See more on testguy.net
