Abstract: A digital level is disclosed that includes a digital display for displaying the angle of inclination between a straight edge of a digital level and a desired reference plane. An alarm is also included to indicate whenever the digital level is held parallel to a desired reference plane, such as alevel horizontal plane, or a vertical plane. The level transducer employed within the digital level includes a rotating member that is weighted so as to always be aligned with a gravitational field in which the level is used. The body of the level includes flip-up sights so that it can readily be used as a transit. A microswitch located on the underneath side of the level automatically powers the circuitry used in connection with the sensing circuitry and digital display whenever the level is placed on a planar surface.
