7.2.3. Soil resistivity measurement of 4-pole equidistant method
The four grounding piles are arranged in a straight line, and the distance between the grounding
piles are equal to a. The depth of the ground pile driven into the ground h is not more than one
twentieth of a. A may be 5,10,20,30,40 m and so on (default is 20m). When the area of the tested
site is large, the spacing should be larger.The resistivity is obtained by the ground resistance R: =
2πaR
Test mode selection: Soil R VF 1A
