Each house, after installation, needs to be tested for compliance. The other reference standard is the grounding resistance value. The next one is to measure the grounding resistance value by the precision four-wire method. Each house, after installation, needs to be tested for compliance.

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 is 0～600V.
As shown above: ES3010E standard accessories include: 1 instrument, 1 instrument box, 4 auxiliary grounding rods, 4 test lines, 2 simple test lines, 1.5V battery, 6 sections, user manual warranty 1 out ES3010E Grounding resistance soil resistivity tester This time, the four-wire precision test grounding resistance is used (refer to the following wiring). The distance between the default grounding rods is 5 meters.
Ground rod current is extremely red
Grounding rod voltage is very yellow
Clamp both green and black to the ground lead of the device
Insert the corresponding color into the meter interface
Overall picture
Rotate the switch to the grounding resistor RE, this is the measurement of the grounding resistance
Press the TEST red button to start the test.
Countdown to 10 seconds, there are still 7 seconds to complete
The grounding resistance is obtained, 3.28 ohms, the grounding condition is good at this time, and the inspection is qualified.
Measurement completed
The above is an example of the operation of the grounding resistance value of the measuring device (simplified) of the Guangzhou Sengeng ES3010E grounding resistance soil resistivity tester (simple type)
