Soil resistivity measurement case

Guangzhou Energy ES3010E Grounding Resistance Soil Resistivity Tester (simple type) can measure the grounding resistance, soil resistivity, grounding voltage measurement and other functions using the 2, 3, and 4 wire methods. Before designing the ground net of each house or each machine room, it is necessary to consider how large the ground net is to meet the design requirements. An important parameter judged at this time is the soil resistivity. Guangzhou Energy ES3010E Grounding Resistance Soil Resistivity Tester (simple type) can measure the grounding resistance, soil resistivity, grounding voltage measurement and other functions using the 2, 3, and 4 wire methods. The grounding resistance range can reach: 0.00Ω～30.00KΩ, the soil resistivity range can reach: 0.00ΩM～9999KΩM, and the voltage range: 0～600V. Before the design of the ground network of each house or each machine room, the ground network must be considered. It is necessary to make a large cloth to meet the design requirements. An important parameter judged at this time is the soil resistivity. Prepare to measure soil resistivity at 5 meters depth Open the instrument box, ES3010E standard accessories are: 1 instrument, 1 instrument box, 4 auxiliary ground rods, 4 test lines, 2 simple test lines, 1.5V battery 6 user manual warranty 1 Take out the ES3010E meter, and the rotary switch is in the OFF position. In the shutdown state To measure the soil resistivity, rotate the rotary switch to ρE, it will display 0.00Ωm, measure the grounding resistance and rotate it to RE, the grounding voltage will be VE. Hit the grounding rod under the soil, clamp the grounding rod at one end of the pliers, and hit three more grounding rods. Total: red, yellow, green, black four lines. The grounding wires are arranged in a line in the order of H, S, ES, and E. The distance between each grounding bar is 5 meters. Red, yellow, green, and black correspond to the color socket on the meter. Press the SET button to set the distance. If 5 meters of soil is measured, if the soil is 5 meters deep, the ground rods will be arranged in a straight line. The distance between two adjacent ground rods is 5m, and the meter is set to 5 meters. If it is 30 meters deep, each rod is The distance between the meters is 30 meters, and the meter is set to 30 meters. Then press the TEST button to start the measurement. Start counting down from 10 seconds, now there are still 6 seconds to complete Finally, the countdown is completed, and the soil resistivity displayed at this time is 78.85Ωm. After the measurement is completed, turn the rotary switch to the OFF position and turn it off. Box on the instrument, the work
This case is tested for sandy clay with reference values ​​for soil resistivity: This example is the Guangzhou Senseng ES3010E grounding resistance soil resistivity tester (simple type) to measure the field soil resistivity operation method.
