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

3. Before weighing or balance comparisons, the weights must be kept at a constant temperature to match the laboratory's atmospheric contamination environment status; otherwise, it can significantly affect the data analysis results from our testing technology.

4. Weigh the product after storing it in the original packaging box before use.

5. Weight should be maintained in good condition; it should not be placed in a damp or dusty environment.

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

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