What factors affect the accuracy of Electronic Balance weighing?

The weighing principle of the electronic balance is the principle of electromagnetic force balance. It is mainly an instrument and equipment that uses modern electronic control technology to weigh. Because of its good stability, fast and convenient operation, it also has the advantages of internal calibration or external calibration functions. , Gradually replace the traditional mechanical balance. However, due to improper use or other factors in the weighing process, the weighing results will cause different degrees of error. Regarding the factors affecting the error of the electronic balance, the following is the summary of some experience accumulated by the author in daily operation and application: Electronic Balance installation The environment and installation technicians will have an impact on the accuracy of the balance. A room that is dust-proof, moisture-proof, shock-proof, and protected from temperature fluctuations should be selected as the balance room. Balances that require high accuracy should also be used in a constant temperature room. The balance should be placed on a solid and reliable workbench, and it should be calibrated before use after installation. In this way, the weighing accuracy of the balance may be affected due to the fact that the installation environment does not meet the requirements. For high-precision balances such as one-hundred-thousandth or one-millionth electronic balances, professional and technical personnel from the balance manufacturer should be selected for installation and debugging.
