2-point reading: The plotter reads two regstraton marks n the X-axs drecton (ponts 1-2) and corrects the tlt n the
X-axs.
3-point reading: The plotter reads the ponts at the rght angles of three regstraton marks (ponts 1-2 and ponts 1-3),
corrects the tlt n both coordnate axes and then performs dstance adjustment.
4-point reading: The plotter reads the ponts at the rght angles of three regstraton marks (ponts 1-2 and ponts 1-3),
corrects the tlt n both coordnate axes and then performs dstance adjustment. The addton of the
coordnate values of pont 4 enables even more precse axal tlt correcton and dstance adjustment.
