Abstract
The invention relates to a method for calibration of 2-axis high precision digital angle measurement device, particularly for initializing a planar angle measuring device and an apparatus to generate simultaneous two-dimensional resultant planar angles of full 360° rotation. The planar angle measurement device is, typically but not exclusively, used in concurrent two-dimensional angles leveling, setting and alignment tasks for precision machine setup in the fields of precision engineering and metrology applications.
