3 Focus the circle artifact image in the video window using the video camera focus adjustment.
4 Perform a level measurement using the circle
artifact. The level measurement will zero the z-axis
at the highest video magnification.
5 Measure the circle artifact and create a zero
datum point at the center of the circle feature in the
DRO screen. This will zero the X and Y axes at the
center of the circle. Subsequent measurements of
this circle artifact at other magnifications will result
in X, Y and Z axis offsets with respect to this mag-
nification. These offsets will be entered into the
Magnification setup screen for each corresponding
magnification.
