ＴＧ３２８Ａ（Ｂ）型天平在使用过程中 ,由于受到环境条件影响 ,常常会造成天平两臂的不等。在采用直接衡量时 ,不等臂性误差将被带到衡量结果中去 ,使测量结果失真。按下述方法将准确、快速消除天平不等臂性误差所造成的影响。一、首先检查出不等臂性误差的大小１ 选择天平最 TG328A (B) type balance in the use of the process, due to environmental conditions, the balance will often result in two arms. When using direct measurement, unequal arm error will be brought to the measurement results to distort the measurement results. According to the following method will accurately and quickly eliminate the balance caused by unequal arm error. First, the first check out the size of the inequality arm error 1 select the balance most
