You can do this at home using a multimeter.It is a handheld testing tool that is mostly used to take voltage readings. Advanced digital multimeters can take ampere and ohms (resistance) readings . Ground resistance meters test the resistance of soil to the passage of electric current to determine the adequacy of the grounding of an electrical system by ensuring an adequately large path for fault currents, an indispensable component of a safe, properly functioning electrical system. When clamped over a ground rod and energized, a CT in the tester induces a test current in the circuit via electromagnetic coupling. The current travels through the soil and returns to the rod (but more significantly the jaws of the tester), thus completing the circuit through all available system grounds.

When testing the resistance of a grounding system (rod, grid, etc), the objective is low resistance. The grounding electrode is expected to be capable of carrying large fault currents to ground, while safely diverting around the electrical system, equipment and people. Therefore, the requirement is quite simple: the lower, the better. Ground testers have the follwing characteristics: • AC test current. Earth does not conduct dc very well.

The Ground Resistance Tester Model 6418 measures ground rod, busbar, and grid resistance and impedance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test.
The instrument can measure the ground resistance by simply clamping around the ground conductor, ground rod or equipment ground conductor. The 61-920 also measures leakage AC current up to 30AAC. Larger clamp size (1.25 in.) Earth ground testers It is critical for facilities to have grounded electrical systems, so that in the event of a lightning strike or utility overvoltage, current will find a safe path to earth. To ensure a reliable connection to earth, the International Electrical Testing Association specifies ground electrode testing every three years.
