Problems solved by technology

[0002] At present, there is no uniform standard for the calibration box, and the calibration methods are different according to the product type. For example, the humidity industry sensor also needs to go through a series of calibration processes before leaving the factory to make the output data accurate. In the existing Many times on the equipment, some control devices are used to make the calibration environment meet the calibration requirements, but this process requires a certain amount of time and equipment stability to achieve reliable calibration, and this type of sensor generally needs to collect multiple data. Therefore, the existing equipment can only be calibrated sequentially by adjusting different environments, which consumes a lot of time, especially when readjusting the environmental values, it takes longer to reach a stable state

[0003] In the existing technology, it is difficult to carry out large-scale production, because there are some uncontrollable problems in the whole process. If there are multiple calibration environments in the calibration process, the equipment needs to be switched continuously, but in The stability of the calibration environment will appear during the switching process, so it takes more time to achieve stability after switching the environment. In addition, some sensors still need to be placed on another device during the calibration process. During this transfer process It also needs to be protected, otherwise it will also affect the accuracy of the data during the transfer process

Therefore, there are still many unstable factors on the existing equipment.
