摘　　要：TG328A光电分析天平属于等臂杠杆天平,即支点位于力点和重点连线的正中间。由于理论上要求左臂与右臂需完全相等,但实际使用中无法做到。因此,天平检定员、修理人员和使用者需具有检测天平的不等臂程度及相应的调修能力。The TG328A photoelectric analytical balance belongs to the equal arm lever balance,where the fulcrum is located in the middle of the line connecting the force point and the key point.In theory,it requires the left and right arms to be completely equal,but in practical use,it is impossible to achieve complete equality.Therefore,balance calibrators,repair personnel,and users need to have the ability to detect the degree of unevenness of the balance and corresponding adjustment capabilities.
