ABSTRACT:
An electronic level includes a visual scale having a "fan-like" configuration of a number of elongated wedge-shaped segments. The inclination of the device is shown by graphically illuminating various of the segments on either side of a central segment line. 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.
