Abstract: Horizontal lines and plumb lines which are upright to each other can been emitted from cross line laser. It has been widely used as the benchmark in the construction of building and fitment. Quality of construction can be directly affected by the errors of cross line laser. According to its basic principle, three errors were analyzed about their form reasons and expressions. The methods of calibrating these errors were designed and carried into execution.

Key words: Cross line laser, Measurement errors, Calibration method
