2. Test Projects
2.1. System stability test
| Test tools: array displacement meter ADM, integrated data collector C1000 | Test Description: A 65m array displacement meter ADMS (1 meter/segment) is used for the test. Because of the limitation of the test site, the ADMS cannot be fully extended to test. So the device is fixed on the reel for a stability test. The device number is 280402. The device is set to be vertical. The far end is set as the starting point. The data acquisition frequency is 2 hours / time. The test time is 12 hours. The horizontal displacement and vertical displacement are analyzed with the data of 32 meters (280435 node) and 64 meters (280403 node) from the starting point. |

2.2 Settlement measurement accuracy test of horizontal layout
| Test tools: test stand, grating ruler, array displacement meter ADM, integrated data collector C1000
| Test Description: Fix the observation point of the ADM and the grating ruler. Lift the horizontal layout ADM vertically. Check the value of the grating ruler and the measurement value of the cloud platform for comparison test. |
Test result:
 |  |  |  |
2.3. Horizontal displacement measurement accuracy test of vertical layout
| Test tools: test stand, grating ruler, array displacement meter ADM, integrated data collector C1000
| Test Description: Fix the observation point of the ADM and the grating ruler. Move horizontally the vertical layout ADM. Check the value of the grating ruler and the measurement value of the cloud platform for comparison test. |
Test result:
 |  |  |
2.4. Convergent measurement accuracy test of annular layout
| Test tools: test stand, grating ruler, array displacement meter ADM, integrated data collector C1000. | Test Description: Fix the observation point of the device and the grating ruler. Move horizontally the annular layout device. Check the value of the grating ruler and the measurement value of the cloud platform for comparison test. |
Test result:
 |  |  |
2.5. Measurement accuracy test of torsion compensation
| Test tools: test stand, grating ruler, array displacement meter ADM, integrated data collector C1000.
| Test Description: Fix the observation point of the device and angle dial. Twist the vertical layout device. Check the measurement value of the cloud platform and carry out the torsion correction compensation. Compare the results before and after the torsion compensation. The torsion angle of this test is 9 °, as shown in the figure below.
| Test Result:
| Test Result: |
2.6. Temperature influence test
| Test tools: High and low temperature testing machine, array displacement meter ADM, integrated data collector C1000. | Test Description: Put the device into the high and low temperature testing machine and set the temperature to -35°. Close the machine after the temperature reaches standard level and wait for the inner temperature rise to room temperature.
| Test Result:  | Test Result:  |
2.7. Temperature measurement accuracy test
| Test tools: room temperature thermometer, array displacement meter ADM, integrated data collector C1000. | Test Description: Place the device in the test environment and read the ambient temperature of the device by the room temperature thermometer, and then compare with the temperature of the device read by the cloud platform. |  | Test Result:
|
2.8. Waterproof test
| Test tools: simulated deep sea hydrostatic testing machine, array displacement meter ADM.
| Test Description: Put the tested ADMS into the pressure retaining bin of simulated deep sea hydrostatic testing machine. Open the machine to maintain the pressure of 5MPa for 48 hours, and then take out the ADMS and cut it to see whether there is water in the interior. | Test Result:
|
2.9. Tensile test
| Test tools: tensile testing machine, array displacement meter ADMS | Test Description: Put the tested ADMS into the tensile testing machine and start to test tensile until the ADMS is snapped.
| Test result：  |
2.10. Power consumption test
| Test tools: digital power supply, array displacement meter ADMS, integrated data collector C1000. | Test Description: The tested device is 65m ADMS. Power on the integrated data collector (without ADMS) and check the power consumption. Then connect ADMS and check the power consumption. | Test Result:
