Before using the weights for research, first clean them by using a brush and a wipe provided by your company to remove any surface dust and stains.

2. Do not touch heavy objects with your hands directly. When handling weight, please wear a special pair of gloves.

3. Before weighing or comparing with weights, they must be kept at a constant temperature to match the laboratory's atmospheric pollution environment status. Otherwise, it can severely affect the data of our technical analysis results.

4. Weight should be stored in the original packaging box and then used.

5. The weight should be kept in good condition; it should not be placed in a damp, dusty environment.

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

7. Do not handle weights with bare hands. When using weights, utilize the students' own network technology tools for analysis and extraction.

8. Before use, remove dust from the surface with a soft brush or cloth.

9. Before the balance testing, the weights should be kept at a constant temperature to improve the laboratory's atmospheric environment.
