Method for measuring a measurement distance between a rotating laser and a laser receiver

A method for measuring a horizontal measurement distance (DH) or vertical measurement distance (DV) between a rotating laser (11) that emits a first laser beam (22) that is rotatable about an axis of rotation axis (21) and/or a stationary second laser beam (23) and a laser receiver (12) with a detection field (18) with a measurement function, comprising the steps of:

• aligning the rotating laser (11) in a horizontal position or a vertical position and aligning the laser receiver (12) in a longitudinal arrangement or a transverse arrangement;
• aligning the rotating laser (11) at an angle to the laser receiver, in which a device axis of the rotating laser (11) is aligned towards the detection field (18) of the laser receiver (12);
• and
• aligning the rotating laser (11) in a defined state using a leveling device (54), wherein the defined state is formed as a horizontal state in the horizontal position of the rotating laser (11) and as a vertical state in the vertical position of the rotating laser;
• wherein the rotating laser (11) is inclined from the defined state by an inclination angle (α) in a direction of inclination, an incident position of the inclined laser beam on the detection field (18) of the laser receiver (12) is determined as a first measuring point, a distance of the first measuring point from a zero position of the detection field (18) is stored as a first height (h1=h(α)), and the measurement distance (DH, DV) between the rotating laser (11) and the laser receiver (12) is determined as a first distance (d1) from the inclination angle (α) and the first height (h1=h(α)).
