Abstract
Dispositif de surveillance et de signalisation du bon état de fonctionnement d'un appareil de mesure de gaz alimenté par une batterie incorporée rechargeable. Ce dispositif est formé de diodes luminescentes 3, 3' logées dans un boîtier en matière plastique à couvercle transparent, qui sont branchées, avec une émission de couleur différente, dans un montage basculeur, dont les valeurs de commutation peuvent être ajustées par des résistances de réglages 17, 18.
