On December 14, 2015, Ruihua Group, which is contracting a construction project in Guangzhou, is underway.
For the needs of the design of the construction network, invited two technicians of Guangzhou Zhengneng Electronic Technology Co., Ltd. to test the soil resistivity of the construction site with the newly purchased instrument ES3010E. The following is the details kimage of the on-test site:
The technicians took the instrumented box to the weedy construction site, and after simply observing the terrain, they were ready to test the soil resistivity at the site:
First, the technician opens the instrument box and explains the usage and use of each equipped tool in detail according to the contents of the manual to the construction personnel:
The technician then began on-site guidance testing.
The technician instructs the on-site construction personnel to take the main unit out of the instrument box. At this time, the rotary switch is in the OFF position and the main unit is in the off state:
The technicians instructed the on-site construction personnel to rotate the rotary switch to ρE and display 0.00Ωm, which can further test the soil resistivity:
The technical staff guides the on-site construction personnel - according to the corresponding color, the test lines are respectively connected to the rear of the host P (H), C (S), ES, E four interfaces:
The technicians instructed the on-site construction personnel to drive the four grounding rods into the soil to be tested according to the adjacent 5 meters, and press the test lines according to P(H), C(S), ES, E. The sequence is sandwiched between four ground rods:
The technician guides the on-site construction personnel - press the SET button to adjust the test distance to 5 meters:
The technician guides the on-site construction personnel - press the TEST button to display the countdown for 10 seconds, and the host starts to operate:
The technicians instructed the on-site construction personnel - the countdown was over and the soil resistivity of the site was measured to be 78.85 Ωm:
The technicians instructed the on-site construction personnel - the rotary switch was rotated to the OFF position, the main unit was turned off, and the instrument accessories were cleaned and reloaded into the instrument box. The test was completed:
Through this on-site test, Ruihua Group measured the accurate value of the soil resistivity of the site, and the building design has got a stronge accordance with it.For this, Ruihua Group expressed its sincere gratitude to Xuneng Electronics and its technical staff for the guidance and testing of the economist electronics technicians who can personally arrive at the construction site. Zhengneng Electronics also expressed its gratitude for the feedback and test cases provided by Ruihua Group,and congratulated the Ruihua Group on the successful completion of the construction.
