Abstract

L'invention concerne des appareils de mesure produisant L'appareil décrit comporte un moyen de mesure produisant des signaux représentant des valeurs angulaires ou linéaires. Dans une mémoire adressable sont stockées des valeurs de correction pour les valeurs mesurées. On peut ainsi produire, à partir d'un synchrotransmetteur à fort pouvoir de résolution mais peu précis, un instrument trés précis. Application : mesures d'angles tres précises.The invention relates to measuring apparatuses producing. The disclosed apparatus comprises a measuring means producing signals representing angular or linear values. Correction values for the measured values are stored in an addressable memory. We can thus produce, from a synchrotransmitter with high resolving power but not very precise, a very precise instrument. Application: very precise angle measurements.
