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.
