<p>The invention relates to a rotating construction laser comprising a laser core module with a laser unit for emitting a laser beam and rotation means for rotating the laser beam around an axis of rotation thus defining a laser beam plane. The rotating construction laser is provided with an outer pivoting mechanism attached to the laser core module, the outer pivoting mechanism being operable to tilt the laser core module around an X-axis as a first axis of rotation and around a Y-axis as a second axis of rotation. The rotating construction laser further comprises a dual grade mechanism with a first level sensor operable to indicate a rotation of the laser core module around the X-axis and a second level sensor operable to indicate a rotation of the laser core module around the Y-axis. The invention is characterized in that both level sensors can be operated mutually independent. The invention also relates to a method of calibration of the dual grade mechanism and a method of generating a pre-defined laser beam plane for light emitted by the rotating construction laser according to the invention.</p> |
