Method for Comparing a Received Beam Incident on a Laser Receiver with a Rotating Laser Beam

Method for comparing a received beam (24) incident on a laser receiver (12) having a rotating laser beam (22), which is moved by a rotating laser (11) about an axis of rotation (21), wherein the laser receiver (12) comprises an evaluation unit (48) and at least one detection field (25) having a longitudinal direction (28) and a transverse direction (29), characterized by the method steps:

• the rotating laser (11) is arranged on a tripod that is adjustable along an axis (15), wherein the axis of rotation (21) of the rotating laser (11) and the axis (15) of the tripod are oriented parallel to a gravitational direction (27) of the gravitational field,
• the laser receiver (12) is oriented in a longitudinal arrangement, wherein in the longitudinal arrangement, the longitudinal direction (2) of the at least one detection field (25) is oriented parallel to the gravitational direction (27) and the transverse direction (29) of the at least one detection field (25) is oriented perpendicular to the gravitational direction (27),
• the rotating laser (11) is adjusted on the tripod (14) in a height direction (16) along the axis (15) at least until the received beam (24) is incident on at:
• least one detection field (25) of the laser receiver (12),
• in the longitudinal direction (28) of the at least one detection field (25), the evaluation unit (48) determines an adjustment direction (63;
• 73) of the received beam (24) relative to the laser receiver (12) and
• the adjustment direction (63;
• 73) of the received beam (24) is compared by the evaluation unit (48) with the height direction (16) of the tripod (14).
