Abstract

Cette invention se rapporte à un appareil de détection de forces à boîte dynamométrique multicharge, qui comprend une unité de commande (50) permettant de déterminer l'emplacement et l'amplitude d'une force appliquée. Des forces à impulsions peuvent être distinguées des forces statiques, ce qui permet à l'utilisateur de démarrer les fonctions préprogrammées en effleurant le plateau (202) de la balance en des emplacements spécifiés (206).
