Instrument features:
1. Strong test ability: meet the requirements of "impact absorption / vertical deformation" test methods in many domestic and foreign test standards for sports venues;
2. Strong adaptability to the environment: the instrument is nimble and convenient to move, convenient to test in various environments;
3. The main structure of the instrument adopts integrated design, and the test spring needs to be replaced for impact absorption and vertical deformation test;
4. High precision and good data repeatability: high precision pressure sensor of famous brand is adopted to ensure the accuracy and stability of test force value;
5, High speed data acquisition system: high speed data acquisition system structure based on ARM9 is adopted, system clock circuit design and hardware double buffer are adopted to realize continuous acquisition and storage, and system anti-interference design is added to solve the problem of signal acquisition;
6. High test efficiency: 5 minutes to complete the test times impact absorption test (3 times) vertical deformation test (3 times);
7. Control interactive interface: notebook computer is adopted, which is convenient to carry;
8. Fast processing speed: adopt AD acquisition mode, the highest speed rate reaches 500KHz, and the processing capacity and use speed are improved across levels;
9. According to the needs of customers, configure a rich software interface (multilingual environment to meet the needs of users in different countries);
10. With the design of portable lithium battery power supply, the user does not need external power supply when testing V on site, that is, use it and test it immediately, which is convenient and fast. The power supply of the instrument can stand up for 48h.
