接着，分析了采用低精度仪表自动判读方法对高精度仪表进行自动读数时，引入误差会增大高精度仪表的读数误差。
Secondly, the paper analyzes that importing error will increase reading error when the automatic recognition method of low-precision meters is used to recognize the reading of high-precision meters.
实验表明：该读数方法绝对误差为零，非常适合于高精度指针式仪表自动跟踪判读。
The experiment shows that the absolute error of the reading approach is zero, which is applicable to automatic tracking reading of high-precision meter very well.
