Problems solved by technology

[0004] The monitoring instrument needs to be calibrated regularly, so as to ensure the normal operation of the instrument and determine whether there is a fault. In the prior art, the calibration of the monitoring instrument needs to be manually calibrated on site, which is not only extremely inefficient, but also due to manual intervention. , also makes the calibration inaccurate, and limited by the environment, the calibration cannot be achieved
