A method and apparatus for remotely verifying the calibration status of a diagnostic instrument, for example, following remote installation of a software upgrade on the instrument. In one example, a method of verifying the calibration status of the instrument, includes retrieving stored raw calibration test data generated during a previously-performed calibration of the instrument, processing the raw calibration test data to generate a diagnostic reading, comparing the diagnostic reading to a known nominal reading, and based on the comparison, generating an output indicative of the calibration status of the instrument. In one example, the method is performed without contemporaneously measuring a calibration object with the instrument and therefore, without activating the measurement head or measurement optics of the instrument.

L'invention porte sur un procédé et un appareil pour vérifier à distance l'état d'étalonnage d'un instrument de diagnostic, par exemple, en suivant une installation à distance d'une mise à jour de la version du logicielle sur l'instrument. Dans un exemple, un procédé de vérification de l'état d'étalonnage de l'instrument comprend l'extraction de données de test d'étalonnage brutes stockées, générées durant un étalonnage de l'instrument préalablement effectué, le traitement des données de test d'étalonnage brutes pour générer une lecture de diagnostic, la comparaison de la lecture de diagnostic à une lecture nominale connue, et sur la base de la comparaison, la génération d'une sortie indicative de l'état d'étalonnage de l'instrument. Dans un exemple, le procédé est réalisé sans mesure simultanée d'un objet d'étalonnage avec l'instrument et par conséquent, sans activation de la tête de mesure ou de l'optique de mesure de l'instrument.
