At present, the gauge with pointer is widely used in the producing process.
目前生产过程中普遍采用的测量仪表是指针式仪表。
But, usually, detecting of the gauge with pointer is by manual work, after long time for vision work, eyes will get tired, and this leads to low detecting precision and long detecting period.
现在，对很多没有计算机操作界面的指针式仪表的检定通常都是由人工来读数和调节，然而，人的眼睛在大量的视觉工作之后会出现视觉疲劳，造成了检定精度低，检定周期长。
