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.

Test result

Horizontal displacement stability of 32m position (280435 node):0.4mm

Vertical displacement stability of 32m position (280435 node): 0.05mm

Horizontal displacement stability of 64m position (280403 node): 0.6mm

Vertical displacement stability of 64m position (280403 node): 0.2mm
