Abstract

Improvements in the devices for signaling a separation between a measured value and a reference value, consisting of a graduation support, means representative of the reference value, means representative of the signal of separation between the measured value and the reference value, characterized in that the representative means of the separation signal are constituted by a set of light-emitting diodes arranged behind said graduation support and providing light areas behind said support, this support being at least partially translucent or transparent to allow the less partially the area or areas illuminated by said diodes.
