1. A method for comparing a received beam incident on a laser receiver with a rotating laser beam moved by a rotating laser about an axis of rotation of the rotating laser, wherein the laser receiver includes an evaluation unit of a microcontroller and a detection field having a longitudinal direction and a transverse direction, comprising the steps of:
disposing the rotating laser on a tripod that is adjustable along an axis of the tripod, wherein the axis of rotation of the rotating laser and the axis of the tripod are oriented parallel to a gravitational direction of a gravitational field;
orienting the laser receiver in a longitudinal arrangement, wherein in the longitudinal arrangement, the longitudinal direction of the detection field is oriented parallel to the gravitational direction and the transverse direction of the detection field is oriented perpendicular to the gravitational direction;
adjusting the rotating laser on the tripod in a height direction along the axis of the tripod at least until the received beam is incident on the detection field of the laser receiver;
determining, in the longitudinal direction of the detection field, an adjustment direction of the received beam relative to the laser receiver by the evaluation unit; and
comparing the adjustment direction of the received beam by the evaluation unit with the height direction of the tripod.
