分析天平的灵敏性、不等臂性、示值变动性及正确性被称为分析天平的四大性能。作为一种精密度和灵敏度都较高的仪器,四大性能的好坏直接影响到该台天平量值的准确性。对分析天平灵敏性、不等臂性和示值变动性故障的调修,也就是天平计量性能故障的调修,调修主要集中在天平的心脏——横梁上。而灵敏性、不等臂性和示值变动性故障是天平在日常使用中经常发生的故障,鉴于此,计量检定人员掌握正确处理这些故障的方法十分必要。
Analytical balance sensitivity, unequal arm, show the value of change and correctness is called the analytical balance of the four properties. As a high precision and sensitivity instruments, the four properties of a direct impact on the quality of the scale of the accuracy of the scale. Analytical balance sensitivity, unequal arm and show the value of changes in the fault repair, that is, balance measurement performance problems of the repair, repair mainly concentrated in the heart of the balance - the beam. Sensitivity, unequal arm and indication variability faults are common failures in day-to-day use of balances. In view of this, it is necessary for metrologists to master the correct handling of these faults.
