Description

technical field

[0001] The invention belongs to the technical field of testing machine measurement and control. Background technique

[0002] With the rapid development of digital technology, the testing machine industry has also moved from the previous analog control technology to digital control, but this so-called digital control technology can only use digital control in some unit circuits in the entire analog system. Still rely on the discrete components of the resistance-capacitance circuit to adjust its magnification and item sensitivity and other parameters. This method cannot effectively eliminate the impact of the surrounding environment and the discreteness of analog components on the accuracy of the entire system, let alone realize the mass production of the entire control system. This has brought a great impact on the electrical performance of the whole system and also brought a lot of troubles to production and maintenance.

[0003] In China, the two technolog...
