Distance measurement system comprising a distance sensor (2, 16) for measuring a distance (a) between the distance sensor (2, 16) and a measurement object and an optical auxiliary positioning member for the distance sensor (2, 16) in order to support positioning of the distance sensor (2, 16) relative to a measurement object, wherein the distance sensor (2, 16) and the auxiliary positioning member are two separate units, with the auxiliary positioning member comprising: a light source which is configured to produce an adjustment light beam, wherein the adjustment light beam has a wavelength (λ) in the visible range and is suitable for producing a light spot on a measurement object, and a control unit which has a distance input and which, in order to control at least one property of the adjustment light beams, is connected to the light source so as to communicate, wherein the control unit is constructed to evaluate an input value which is input into the distance input and, based on an evaluation result, to influence at least one property of the adjustment light beam in such a manner that the adjustment light beam enables conclusions relating to the input value, wherein the distance sensor (2, 16) is connected to the auxiliary positioning member so as to communicate and inputs an input value which is representative of a measured distance value into the distance input of the auxiliary positioning member, wherein the distance sensor (2, 16) is formed by an optical sensor and is configured to transmit a measurement light beam, wherein an optical coupler is arranged in such a manner that the optical coupler couples the measurement light beam transmitted by the distance sensor and the adjustment light beam in such a manner that the measurement light beam and adjustment light beam can be directed by means of a common optical means to the measurement object. a distance sensor (2, 16) for measuring a distance (a) between the distance sensor
