1. Before conducting research with the weights, first use a company's own cleaning brush and wiping cloth to remove surface dust and other污渍 from the weights.
2. Do not touch heavy objects with your hands directly. When handling weight, wear a special pair of gloves.
3. Before weighing or balance comparison, all weights must be kept at a constant temperature to match the laboratory's atmospheric contamination status. Otherwise, it can significantly affect the data from our testing and technical analysis results.
4. Weight should be stored in the original packaging box before use.
5. Weight should be kept in good condition; 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 the weights with bare hands. When using the weights, utilize the students' own network technology tools for analysis and extraction.
8. Before use, clean the surface dust 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.
10. Handle lifting and placement of heavy items with gentleness.
