在生产车间现场标定大型电子秤是一件很复杂的事情，标定时需要运送几十吨MI级标准破码，并且需要无车专门配合。进行这项工作经常受到现场条件限制，无法进行标定而影响了正常的生产秩序。使用中的电子秤时常发生一些传感器及机械部分故障都正常，只因称重显示器元件损坏或显 It is a complicated task to calibrate a large electronic scale in the production workshop. When calibrating, it needs to transport dozens of tons of standard MI codes, and it requires a car-free cooperation. This work is often limited by on-site conditions and can not be calibrated to affect normal production order. The use of electronic scales often occur some of the sensors and mechanical failure are normal, simply because the display component damage or significant
