CALIBRAT is a software package designed to facilitate quality assurance plan implementation, particularly in the French military establishment. CALIBRAT is intended to be used for a quality assurance plan for measurement devices (mainly multimeters). It includes a high-level language for writing control and calibration procedures and a result database for analysis. Complementary tools like operator dialog, specialized editor, and help for the constitution of a devices library, makes its use very easy and versatile. The set of powerful tools has been developed with specific IEEE-488 bus command oriented keywords and an instrument manager to provide independence between the language and the instruments. CALIBRAT can be run on a personal computer with a GPIB-PC1 or -PC2 National Instruments Board IEEE-488 bus controller. >
