The instrument cannot maintain its factory performance forever after being purchased, nor can it be used with confidence just because it has a calibration label. Whether they are engaged in R&D or responsible for production, they are unwilling to face the adverse consequences caused by "errors": increased R&D/production line testing costs, substandard yield rates, difficulty in improving system measurement uncertainty, etc. In the video, Dr. Liu tells us how to use instrument calibration to improve test accuracy.
