4. Weights should be stored properly and not placed in damp, dusty environments.

Do not touch the weights with bare hands. Use a tool to remove the weights when handling them.

6. Before calibration, the weights should be maintained at a constant temperature to achieve the laboratory's temperature conditions.

7. Groups of weights must not be mixed with other weights.

Avoid using thick acids, alkalis, and oils during use.

9. After use, clean the weights with alcohol, let them air dry naturally, and store them in the original packaging box for future use.

10. Weights should be calibrated regularly based on usage frequency, and calibration records should be kept.

11. If there are issues with the weight performance, it should be immediately sent to a testing facility for inspection.
