The Pinion/Voyager model RTG-210 Resistance to ground meter is a simple to use, highly repeatable measuring device for determining the resistance to ground. The principle of operation is as follows;
A voltage, V(30 Volts), is applied to the grounding cable which is connected to ‘ESD’ ground. The center probe contact (spring loaded) provides a ground return of the current supplied by the grounding cable. The resistance to ground of the material being measured is expressed as ten to some power, written as Ohms = 10^x.
