RING LOCATION


The next step is for the computer 
to locate each ring along each 
meridian.  There will be a green 
crosshair near the center of the 
screen.  Use the arrow keys to 
center the crosshair in the center 
of the center ring.  Press enter.  
The unit may automatically fine 
adjust the crosshair and then 
proceed to locate each ring.

Green circles with red dots at 
each data point will overlay the 
ring pattern.

If this looks complete just hit enter to “save and continue”.    If it has not located some rings you can manually identify the proper spots by highlighting the “manual digitization” and hitting enter.
