Description

Technical Field

[0002] The statements in this section merely provide background technology related to the present invention and do not necessarily constitute prior art.

[0003] In a traditional migration test system, the weighing device is generally installed inside the test system. Since the entire test shell is used to control the temperature of the evaporation chamber during the migration test, a high temperature and high humidity environment will be generated inside the test shell. At this time, the weighing indication cannot be directly read from the outside of the shell, that is, the indication cannot be observed using the perspective window on the shell.

[0004] For example, patent number CN219935577U provides a total migration tester, which protects the weighing components to avoid errors in the weighing results. However, it still controls the evaporation temperature through the entire test chamber and cannot avoid the high heat and high humidity environment in the shell; therefore, most existing weighing devices directly send weighing data to the control software of the device through wired communication. When the communication is abnormal or the weighing data is questionable, the weighing data cannot be effectively verified. Utility Model Content
