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 the weights when using them.

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

7. Sets 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 wine 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 are issues with the weight performance, the weights should be sent to a testing facility for inspection immediately.
