Webinterest in earth testing. Earth resistivity measurements can be used conveniently for geophysical prospecting — to locate ore bodies, clays, and water-bearing gravel beneath the earth’s surface. The measurement can also be used to determine depth to bed rock and thickness of glacial drift. WebJun 15, 2024 · This test is performed with an earth resistance test set that essentially comprises two circuits, as shown in Figure 1. The first circuit includes a voltage source and an ammeter, and it is brought out to the instrument’s current terminals. The second circuit includes only a voltmeter, and is brought out to the instrument’s voltage terminals.
