Handle weights with care.

Before use, wipe the dust from the surface of the weight with a soft brush or cloth.

3. Inspect the weights inside the box before and after use to prevent loss.

4. Weights should be properly stored and not placed in a damp and dusty environment.

Do not handle the weights by hand. Use tools to remove the 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. 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 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 immediately sent to a testing facility for inspection.
