1、 为什么分析天平的全自动校准经常发生？ 如何避免呢？

1、 Why does the fully automatic calibration of the analytical balance occur frequently? How to avoid it?

分析天平的频繁校准主要是由于环境的变化。 目前，有两种类型的自动定位校准：

The frequent calibration of analytical balances is mainly due to changes in the environment. At present, there are two types of automatic calibration for positioning:

温度触发和时间触发。 时间触发就是在分析天平上设定时间，温度触发就是根据环境的变化进行自动校正。

Temperature trigger and time trigger. Time triggering is to set time in the analytical balance, and temperature triggering is to do automatic correction with the change of environment.

这种现象发生的频率主要是由于温度波动造成的，所以要避免室内温度波动。

The frequency of this phenomenon is mainly due to temperature fluctuations, so avoid temperature fluctuations in the room.

2、如何避免频繁出现校正并且还能保证可以稳定测量数据？

2、 How to avoid frequent correction and ensure the stability of measurement data?

保持电子衡器称重室内的温湿度平衡，避免气流的强对流，避免周围震动，避免高温辐射。 另外，应注意避免频繁的出入称重机房，否则容易造成读数不稳。

Keep the balance of temperature and humidity in the electronic balance weighing chamber, avoid strong convection of air flow, avoid the surrounding vibration, avoid high temperature radiation. In addition, attention should be paid to avoid frequent hand in and out of the weighing room, otherwise it is easy to cause reading instability.
