Handle weights with care.

Before use, clean the scale surface of the weights with a soft brush or cloth to remove dust.

3. Check the weight inside the box before and after use to prevent loss.

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

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

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

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

8. 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 regularly calibrated based on usage frequency, and calibration records should be maintained.

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