Abstract

La présente invention concerne un système de pesée et une balance électronique associée capable d'empêcher la falsification de données. Le poids d'un objet de mesure mesuré en utilisant une unité de mesure de masse (21) est associé à des informations de mesure incluant des conditions ou un état au moment de la mesure, puis est stocké par une unité de stockage de résultat de mesure (30). Une unité de génération de données d'image (22) génère des données d'image en se basant sur le poids de l'objet de mesure et sur les informations de mesure associées stockées dans l'unité de stockage de résultat de mesure (30). Une unité de commande d'affichage (23) affiche les données d'image générées par l'unité de génération de données d'image (22) sur une unité d'affichage (50). Une unité de stockage d'informations d'historique (40) stocke les données d'image provenant d'une ou de plusieurs mesures affichées sur l'unité d'affichage (50) en tant qu'informations d'historique. Le stockage de données d'image en tant qu'informations d'historique de cette manière permet d'empêcher plus facilement la falsification de données par rapport au stockage de données de texte.
