  • Patent number: 6576849
    Abstract: The invention disclosed consists of weighing apparatus and process that includes a new Calibration management utility to automate compliance testing to ISO 9000 requirements and has the “load cell symmetry”, “empty platform” and “test load” readings for each load stored on the weighing apparatus. This weighing apparatus makes periodic tests to determine the health of the load cells in the system, producing a log file to record events such as any detected failure, any suspicious reading, overload condition, or any user defined parameter, and is network enabled to be connected through a LAN via an Ethernet to the Internet.
