TOOL1SHOoo Multifunctional Resistance Tester DY5500 Insulation Earth Volt Resistance Meter Insulation Earth Ground Test Resistance Meter .01ohm-2000ohm Voltmeter. Since earth has comparatively low resistivity, a voltage drop occurs near the electrode from which the current used to make the measurement flows. Clamp-On Testing is a simple earth resistance measurement method that does not require additional test electrodes. For example, if the total earth resistance is 1.9, the injected current is 9mA and the current flowing to the system is 5mA, the earth resistance can be calculated as follows: The current flowing to the ground, IG = IT IU = 0.009-0.005 = 0.004A, Ground resistance, RG = V/IG = 0.017/0.004 = 4.25.
