Forgólézeres szintezőmüszer kalibrálása

: During the measurement procedure, the laser beam of the rotary laser level equipment always have to roll over horizontally. The tail swing of the horizontal roll over is limited, and only about ± 0.5mm/m allowed. Positional error of the rotary laser level equipment can be caused by horizon-skewness and cone error. Previous studies could not separate the effect of the mentioned angle errors, but our geometric modeling made it possible, that the angle errors can be separately determined by special located foot rules. In order to determine separetely the angle errors, it is necessary to use the height errors detected at this special located foot rules.
