4. Weights should be properly stored and not placed in a damp and dusty environment.
Do not handle weights with bare hands; use a tool to remove weights when using them.
6. Prior to calibrating the balance, the weights must be maintained at a constant temperature to achieve the laboratory's temperature conditions.
7. Do not mix different sets of weights together.
Avoid using thick acids, alkalis, and oils during use.
9. After use, wipe the weights clean with alcohol and let them air dry naturally before storing them in the original packaging box for future use.
10. Weights should be calibrated regularly based on usage frequency, and calibration records should be maintained.
11. If there are issues with the weight performance, it should be sent to a testing facility for inspection immediately.
