如果一台秤的稳定性不好,其抗干扰能力就很差。一个很小的外界干扰(如气流、震动等),均可以造成计量杠杆较大的位移。稳定性差的台秤,仅靠调整计量杠杆是很难达到平衡状态的。时常出现计量杠杆不是上去下不来,就是下来上不去。总之,摆动总是忽上忽下,无规律可循。原因:1.稳定程度随着载荷的增加而降低,也就是说小秤量时稳定,大秤量时不稳定。这种情况是由于
If the stability of a scale is not good, its anti-interference ability is very poor. A small external interference (such as airflow, vibration, etc.), can cause a larger displacement measurement lever. Poor stability of the scale, only by adjusting the metering lever is difficult to reach equilibrium. From time to time there is a measurement of leverage is not up or down, that is, up and down. In short, the swing is always up and down, no law to follow. Reason: 1. The degree of stability decreases with the increase of the load, which means that when the small scale is stable, when the large scale is unstable. This situation is due to
