A collection of precautions for using electronic floor scales?

1. Avoid collisions during the use of electronic floor scales. Although anti-collision limit measures are taken in the structural design of the sensor and electronic scale, excessive collision will cause the sensor to be damaged before the limit measures take effect. Damage causes changes in electrical parameters, affecting the measurement accuracy of the electronic scale. 2. Choose a floor scale with an appropriate range according to the weight of the items to be weighed. The accuracy of an electronic scale with a maximum weighing capacity of 3 kg and a division value of 1 gram is 1/3000. If you use it to weigh 2 kilograms of items, its measurement accuracy is 1/2000. If you use it to weigh 100 grams of items, its measurement accuracy is only 1/100. 3. The impact of ambient temperature on weighing accuracy. National standards require that Class III scales ensure accuracy indicators within the ambient temperature range of 0°C to 40°C. If the ambient temperature exceeds this range, the weighing accuracy may be affected. 4. The impact of vibration and wind on weighing accuracy For an electronic scale with a maximum weighing capacity of 15 kilograms and a graduation value of 5 grams, vibration and wind have little impact on weighing accuracy. For an electronic floor scale with a maximum weighing capacity of 200 grams and a division value of 0.1 grams, vibration and wind will cause the display numbers to jump. 5. The impact of environmental humidity and acid, alkali vapor or liquid on electronic scales. The national standard requires that the accuracy index of Class III scales be guaranteed at an ambient humidity of ≤90%, and it is required to avoid contact with acid, alkali vapor or fluid. For electronic floor scales without special treatment, >90% humidity and acid, alkali vapor or fluid attached to the circuit will cause changes in circuit parameters and even damage the circuit. For the above usage environment, products with waterproof properties can be used. 6. Annual inspection requirements for electronic floor scales: The accuracy of electronic scales may change due to use, environment and device aging. Regular verification must be carried out in accordance with the requirements of national metrological technical regulations. Electronic scales that have not been calibrated or have exceeded the calibration validity date cannot be used.
