Introduction:
The system is for the mechanics discipline, civil engineering structures, and mechanical disciplines. Combined with institutions of higher learning teaching theory courses, the full set of test methods may provide students with laboratory equipment to enable students to learn through visual experiments to deepen their theory. The system is an essential teaching experimental equipment.
The Configuration of the System
Configuration of the data acquisition instrument, amplifiers, and sensors can also be used for scientific research and experiment with optional software of signal acquisition, process, and analysis.
