diagnostics.
Example of the Adjustment
Here is a sample of the magenta radar image. Looking down the left
side for both X and Y you can see the X value is close to correct. It
may be a little to the right. The Y value for magenta is incorrect. The
magenta radar image is too far above the black. In the case of Y,
increase the value for Y to move the magenta image down the page.
This may not seem intuitive, but increasing the value increases the
timing delay, thus moving the image down the page. The images
may be off by different amounts. Make the best overall judgment
using all the radar images on the left side.
When the Y value is correctly adjusted the magenta radar image
should look like the following example. The Theta adjustment is
done in the same manner as the Y except theta values are taken
from the right side of the test pages.
