14. Adjustment Specifications for Instrument Adjustment Setting the reference position of the measuring table Goal the position of the signal disk measuring table motor control and the position of the light barrier measuring table reference control must be adjusted in such a way that reference position and measuring position are identical The reference position is the position reached after a defined downward travel from the measuring position to the light barrier It is hence a defined position of the measuring table in the measuring module Execution 1 The measuring table must be spaced apart from the measuring head carrier by 16 4 0 1 mm This is the space from the surface of the measuring head carrier to the surface of the measuring table To measure this distance the center of the measuring head carrier must be brought in alignment with the two mounting points of the measuring table In addition the difference in distance between MH1 carrier and MH2 carrier 16 4 to the surface of the measuring table must not exceed 0 1 mm This distance is measured through the hole in the measuring head carrier If this condition is not met the procedure must be repeated 2 Remove the screw that holds the signal disk Adjust the lower edge of the cut in the signal disk to the center to the light barrier Now fix the position of the signal disk by tightening the screw To check this move the measuring table down by using the se
