Keep an eye out for everyday use of precision balances

　　1. Measure multiple times and take its uniform value (3 to 5 times).

　　2, the room should avoid direct sunlight, it is best to choose a shady room or the use of shading methods.

　　3. Precision balances should be separated from the source of earthquakes, such as railways, highways, shock machines and other shocking machinery, and earthquake prevention measures should be taken when there is no way to avoid them.

　　4. The temperature in the working room should be constant, preferably about 20 °C.

　　5. The relative humidity in the studio should be between 45% and 75%.

　　6. The reading should be fixed after loading, such as reading with the indication value of 5 seconds after loading or reading the indication value when it is displayed in units.

　　7, fully preheat before use, generally should be more than 30 minutes, the higher the correctness of the balance, the warm-up time should be extended accordingly.

　　8. Before use, use the scale weight correction, and the weight of the corresponding grade selected for different correctness balances.

　　9, should be wide away from the heat source and high strength electrical characteristics: wave particle radiation and other environments.

　　10. The work room should be clean and clean to avoid the influence of air flow.

　　11. Adjust the spirit level bubble to the middle position before use.
