Title
(EN) ELECTRONIC LEVEL DISPLAYING INCLINATION USING A MULTI-SEGMENT FAN-LIKE DISPLAY
(FR) NIVEAU ELECTRONIQUE D'AFFICHAGE D'INCLINAISON A AFFICHAGE EN EVENTAIL MULTI-SEGMENTS
Abstract
(EN)
An electronic level (10) includes a visual scale having a 'fan-like' configuration of a number of elongated wedge-shaped segments (12b-e). The inclination of the device is shown by graphically illuminating various of the segments on either side of a central segment line (12a). When the device is at a null (typically level or plumb) only the central segment is illuminated. Each segment indicates a predetermined amount of inclination from the null.
(FR)
Niveau électronique (10) comportant une échelle visuelle en éventail comportant plusieurs segments allongés en forme de coin (12b-e). L'inclinaison de l'instrument est présentée par l'illumination graphique des segments situés de part et d'autre d'une ligne de segment centrale (12a). Lorsque l'instrument est à l'horizontale (typiquement niveau ou plomb), seul le segment central est éclairé. Chacun des segments indique une valeur donnée de l'angle d'inclinaison par rapport à l'horizontale.
