Abstract

Lorsqu'un compteur de temps électronique se trouve en mode économiseur d'énergie, avec arrêt de l'indication du moment présent, on décide si la tension de charge fournie par un gros condensateur (48) est supérieure ou inférieure à une tension de référence déterminée. Dans le premier cas, c'est que le gros condensateur a emmagasiné l'énergie nécessaire pour repasser du mode économiseur au mode d'affichage. Il y a fourniture d'énergie et retour à l'indication du moment présent. Dans le second cas, c'est-à-dire lorsque la tension de charge est inférieure à la tension de référence, le circuit de commande cesse d'être alimenté, ce qui évite de gaspiller l'énergie électrique précieuse emmagasinée dans le condensateur. Ce système garantit que le compteur de temps électronique se remet rapidement en marche lorsque du courant commence a être produit.
