Handle weights with care.
Before use, clean the surface dust of the weights with a soft brush or cloth.
3. Check the weights inside the box before and after use to prevent loss.
4. Weights should be stored properly and not placed in damp and dusty environments.
Do not handle the weights by hand. Use tools to remove weights when in use.
6. Before calibration, the weights should be maintained at a constant temperature to achieve the laboratory's temperature conditions.
7. Do not mix different sets of weights.
Avoid using thick acids, alkalis, and greases during use.
9. After use, clean the weights 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 kept.
11. If there's an issue with the weight performance, it should be immediately sent to a testing facility for inspection.
