Method for comparing a reception beam that is incident on a laser receiver with a laser plane that is generated by a rotating laser beam moved by a rotating laser about an axis of rotation, wherein the laser receiver comprises an evaluation unit and at least one detection field having a longitudinal direction, which corresponds to the measurement direction of the laser receiver, and a transverse direction, which is aligned perpendicularly to the longitudinal direction, characterized by the method steps of: ▪ arranging the rotating laser on a rotary platform, which is adjustable about a rotation axis, wherein the axis of rotation of the rotating laser and the rotation axis of the rotary platform are aligned parallel to a direction of gravity of the gravitational field, ▪ aligning the laser receiver in a transverse arrangement, wherein, in the transverse arrangement, the longitudinal direction of the at least one detection field is aligned perpendicularly and the transverse direction of the at least one detection field is aligned parallel to the direction of gravity, ▪ adjusting the rotating laser on the rotary platform in a rotation direction about the rotation axis at least until the reception beam is incident on the at least one detection field of the laser receiver, ▪ continuing the rotation of the rotating laser in the rotation direction about the rotation axis, wherein, during the rotation of the rotating laser, a first incidence position and a second incidence position of the reception beam on the at least one detection field are ascertained by the evaluation unit, ▪ ascertaining an adjustment direction (63; 73) of the reception beam relative to the laser receiver in the longitudinal direction of the at least one detection field by way of the evaluation unit from the first incidence position and the second incidence position of the reception beam, and ▪ comparing the adjustment direction of the reception beam by way of the evaluation unit with the rotation direction of the rotary platform that corresponds to the adjustment direction of the laser plane. ▪ arranging the rotating laser on a rotary platform, which is adjustable about a rotation axis, wherein the axis of rotation of the rotating laser and the rotation axis of the rotary platform are aligned parallel to a direction of gravity of the gravitational field, ▪ aligning the laser receiver in a transverse arrangement, wherein, in the transverse arrangement, the longitudinal direction of the at least one detection field is aligned perpendicularly and the transverse direction of the at least one detection field is aligned parallel to the direction of gravity, ▪ adjusting the rotating laser on the rotary platform in a rotation direction about the rotation axis at least until the reception beam is incident on the at least one detection field of the laser receiver, ▪ continuing the rotation of the rotating laser in the rotation direction about the rotation axis, wherein, during the rotation of the rotating laser, a first incidence position and a second incidence position of the reception beam on the at least one detection field are ascertained by the evaluation unit, ▪ ascertaining an adjustment direction (63; 73) of the reception beam relative to the laser receiver in the longitudinal direction of the at least one detection field by way of the evaluation unit from the first incidence position and the second incidence position of the reception beam, and ▪ comparing the adjustment direction of the reception beam by way of the evaluation unit with the rotation direction of the rotary platform that corresponds to the adjustment direction of the laser plane.
