Abstract

L'invention concerne un appareil pour corriger automatiquement la dérivation des instruments de mesure analogiques. L'appareil utilise un détecteur de température 201 (ou autre variable extérieure) qui, à chaque variation de la température de 10 degrés C par exemple, provoque le calcul par un microprocesseur 203 de nouveaux facteurs de correction de l'erreur de gain et de réglage du zéro sur la base de valeurs de référence du zéro et de la déviation maximale de l'instrument L'invention est applicable aux instruments de mesure.
