在机械天平检定和修理工作中,经常会碰到各种误差,现就目前广泛使用的TG328A型机械天平出现的较集中的现象分析如下:一、天平自身带来的误差由于天平的准确度较高,所以安装稍有一点不正确就可能引起天平的变化,产生较大的误差。如:天平放置不水平、支点刀承倾斜致使支点刀在摆动中两侧摩阻 In the mechanical balance test and repair work, often encounter various errors, is now widely used TG328A mechanical balance appears more concentrated phenomenon is as follows: First, the balance itself, the error due to the accuracy of the balance than High, so the installation is a little bit incorrect may cause the balance changes, resulting in greater error. Such as: the balance is not placed horizontally, the fulcrum blade bearing tilting caused the fulcrum knife friction on both sides of the swing
