What is the cause of the unstable number of weighing instruments?

The use of weighing instruments must confirm the stability of their measurement, and only in this way will there be no problems in subsequent use. And if the weighing instrument is used, if the number is unstable, the measurement results will definitely be inaccurate. Especially for some laboratories, the meaning of measurement will be lost if the accuracy of zhun degree cannot be guaranteed. So in the process of using weighing instruments, what is the situation that the numbers are not stable?

First of all, the voltage is unstable. Because the environmental conditions of using weighing instruments are different, especially the voltage conditions will have a great influence on the measurement. Therefore, the weighing instrument is used in the direction with stable voltage as far as possible. If the local voltage is always unstable, it can also be directly applied to certain transformer equipment, which will be useful to ensure that the subsequent measurement will not be affected and prevent the line from burning.

Di two, the junction box is not well sealed. If the azimuth seal of the junction box of weighing instrument is not good, the internal humidity will increase overnight. We can open the junction box first and see if there are water drops inside. Be able to blow dry properly and confirm whether there is something wrong. If there is something wrong, it is recommended to replace the junction box directly.

Third, confirm whether there is a problem with the line. In fact, the sensor of weighing instrument is rarely faulty, but if it is in the process of normal use, it presents problems in the line, which will also lead to unstable numbers. Therefore, it is necessary to pay special attention to the inspection of the line, and it is also necessary to confirm the condition of the line during the daily maintenance and inspection of the weighing instrument, so as not to affect the subsequent use.
