This invention relates to an improved digital scale arrangement which employs apparatus for generating an electrical analog signal representing the weight on the scale mechanism. The analog signal is then converted to a digital representation of the weight on the scale under control of a microprocessor or microcomputer. The microcomputer then further processes the digital representation and causes it to be displayed. In accordance with the present invention, a fully automatically operating arrangement is provided for verifying the correct operation of the analog portion, the converting portion, and the digital portion of the arrangement. In addition, the arrangement is also employed to automatically correct the span of the scale under control of the results of the verification operation. |
