Goniometer with graphical information reproduction means for producing information

The goniometer (11) has base (13) defining structure (12) comprising graphic electronic information display unit with two display zones (30a,30b) among which one is arranged in first radial alignment relative to standing axis (14) on structure, while second zone is arranged in second radial alignment which is different from first alignment. The two alignments enclose an angle of 90 degree , and two display zones are automatically and individually activated by control and processing unit as a function of fulfillment of defined angular position criterion by current angular position. Independent claims are included for the following: (1) initialization method for alignment determination of goniometer; and (2) system comprising goniometer.
