The artificialerror is avoided, thus greatly improve the measurement resolution.
消除了人为误差，因此测量分辨率大大提高。

But there are also some problems about the photo-plate image reading system such as low precision, big artificialerror, long processing period, ect.
但成像干板的判读系统也存在着许多问题，判读效率低、人为误差大、处理周期长。

The setting of welding parameters, involving stud lifting height, stud sending depth, lifting and sending speed and so on, can be accomplished by program control, thus the artificialerror is reduced.
