should be 1200 +/- 0.5 pixels. If these values are not within the specified ranges,
click on the Store offset Values in DB OK button in the lower right corner. This will
save the present values and force a repeat of the Find Center of Rotation Calibration
from before. Repeat the Find Center of Rotation Calibration, then this calibration
(A/B/Center Distance Measurement), until these values are within range.
After verifying the yellow values are within the allowable range, zoom in on both the
top and bottom places on each of the three screen shots to verify the image where
the red lines intersect. For all three images, the location of the red lines, relative to
the wire scanned should be about the same, as below:
Notice how the red lines intersect at about the same position on all three images.
Repeat this for the lower intersection of the lines as well. If the red lines intersection
is not similar to the wire and to each other, select the Store offset Values in DB OK
button in the lower right corner. This will save the present values and force a repeat
of the Find Center of Rotation Calibration from before. Repeat the Find Center of
Rotation Calibration, then this calibration until these values are within range.
If the yellow values are good and the intersections all look about even, then this
calibration is complete. Do not click on the Store offset Values in DB button unless
there is a problem with either of the values or locations of red lines.
