What is the method of measuring soil resistivity with a ground resistance tester?
The ground terminal (C2, P2), P1, and C1 are connected with the location of the probe by using a special lead for the earth resistance instrument terminals E.
Along the measured grounding electrode E (C2, P2) and the potential probe P1 and the current probe C1, they are 20 meters apart from each other in line, so that the potential probe is in the middle of E and C, and the probe is inserted into the ground as required.
Switch on the ground switch, ON, select the appropriate gear, press the key lightly, the indicator light is on, and the value shown on the meter LCD is the measured resistance.
Soil resistivity measured by zc-8 needs to be calculated: four ground piles are arranged in a straight line, and the distances between the ground piles are equal to a. The depth of the pile into the ground h is not greater than 1/20 of A. A may take 5, 10, 20, 30, 40m and so on. When the area of the site is larger, the spacing should be greater. The resistance of R to obtain the resistivity: P = 2 pi aR
