1、 為什么分析天平的全自動校準(zhǔn)經(jīng)常發(fā)生？ 如何避免呢？

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

分析天平的頻繁校準(zhǔn)主要是由于環(huán)境的變化。 目前，有兩種類型的自動定位校準(zhǔn)：

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:

溫度觸發(fā)和時間觸發(fā)。 時間觸發(fā)就是在分析天平上設(shè)定時間，溫度觸發(fā)就是根據(jù)環(huán)境的變化進行自動校正。

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.

這種現(xiàn)象發(fā)生的頻率主要是由于溫度波動造成的，所以要避免室內(nèi)溫度波動。

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

2、如何避免頻繁出現(xiàn)校正并且還能保證可以穩(wěn)定測量數(shù)據(jù)？

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

保持電子衡器稱重室內(nèi)的溫濕度平衡，避免氣流的強對流，避免周圍震動，避免高溫輻射。 另外，應(yīng)注意避免頻繁的出入稱重機房，否則容易造成讀數(shù)不穩(wěn)。

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.
