Audit tracking: The full version of audit tracking and user-level permission management. The super administrator can modify everyone's passwords and usernames and trace them, and can modify all operator permissions. User accounts have both a disable and an enable function. When personnel changes occur, accounts can be temporarily locked and then unlocked when needed. The USB export of PDF and Excel data has anti-tampering functions. The audit tracking is quite comprehensive, recording relevant information such as logging in, logging out, modifying data, time, operation steps, and exporting USBs.
User management: hierarchical management, where the super administrator assigns permissions, and administrators can create multiple users. Each user can use their own username, and when logging in, they enter their username and password. User accounts have both a disable and an enable function. The highest authority can modify other people's usernames and passwords and trace them.
Data retrieval function: convenient for users to quickly find the data they want in a large database.
Graph function: during the testing process, graphs can be displayed in real-time, making analysis easier, and the graphs and recorded images can be replayed.
Memory: expandable.
Software upgrade: automatic upgrade via USB, no need to return to the factory.
