摘　　要：机械台秤偏载误差,也叫角差,我们平时称为台秤的四角误差,通常是指将约等于机械台秤最大称量1/3的标准砝码放在承重杠杆重点刀上方相对应的承重台板上,得到同一荷载在承载器的不同区域示值误差与该秤在此测量点的最大允许误差的绝对值作对比,如果超差,就需要进行调修,本文主要了解机械台秤的结构、如何判断机械台秤的偏差是否合格并寻找其原因、着重介绍机械台秤的偏差不合格的调修方法。The deviation error of mechanical platform scale,also known as angle difference,is commonly referred to as the four angle error of the platform scale.It usually refers to placing a standard weight that is approximately one-third of the maximum weight of the mechanical platform scale on the corresponding load-bearing platform above the key blade of the load-bearing lever to obtain the absolute value of the maximum allowable error of the same load in different areas of the load-bearing device.If it exceeds the tolerance,it needs to be adjusted.In this paper,We mainly understand the structure of the mechanical platform scale,how to determine whether the deviation of the mechanical platform scale is qualified and find the reasons,and focus on introducing the adjustment methods for the deviation of the mechanical platform scale that is not qualified.
