WebMay 22, 2024 · The resistance of concern is designated r1. A series of three two-point measurements are taken, as the resistance between the electrode under test and each of two auxiliary electrodes, designated r2 and r3. The three measurements then would be r12 = r1 + r2, etc. The resistance of the test rod can then be calculated as. r1 = [r12 – r23 + … WebGround Testing Techniques. Here are four techniques that you can use for ground testing. Soil resistivity test. This test is the most commonly used. You can use this for testing recently installed grounding systems. As …
