摘要: An automatic measuring instrument plumb, level and score uses a visible laser diode (42) for projecting beam in any of three different modes through an exit window (30) beam. The about the size shape tape measure can be placed on edge (14) vertical offset angle. Placed another (16) rotation 90 °, same output horizontal When installed one its larger flat faces (24), tilt compensation becomes ineffective projects fixed relative to housing. In preferred embodiment, separate mirrors pendulum or cantilever (52) (60) are used correction pitch they selected depending gravity when is side other. other described embodiments, two diodes (124a) (124b) may used, integrated with instruments such as commissioning square. A compensator cover wide range accurate device inclination mode.
