Quality management issues for PC-controlled calibration systems

This paper deals with the management of automatic calibration systems according to quality standards. A set of guide lines is proposed that are based on the development life-cycle model, which requires all the steps of the development process to be managed in a controlled way. Many of these steps are performed by employing suitable check lists, which represent the quality records that allow the correct behavior of the system to be demonstrated, e.g. for third-part accreditation purposes. The system developed at the calibration laboratory of the Politecnico di Torino (SIT center No. 139) is described that has been designed for the verification of digital multimeters and results related to the calibration of specific instruments are reported.
