Because the precision of balance weights is generally high, and there are also many requirements for the environment and operation, what issues should be paid attention to in daily use, and how to extend the service life of electronic analytical balances.

1.1 Do not place the balance weight on the side platform under the air conditioner. The electronic analytical balance that has been moved must be recalibrated to the correct level and undergo a comprehensive inspection of its metrological performance before it can be used.

When weighing hygroscopic, volatile, or corrosive substances, the weighing bottle cap should be tightly closed before weighing, and the weighing should be done as quickly as possible. Be careful not to spill the weighed substance (especially corrosive substances) on the weighing tray or bottom plate; After weighing, the weighed object should be promptly taken away from the balance and the weighing room should be kept clean.

1.3 The same experiment should be weighed using the same balance to avoid errors caused by weighing.
