All measurement concerning the geometry is measured without the contrast
screen mounted.
Measurements are performed with a ruler directly on the picture tube.
All measurements are measured from the phosphors edge, unless other is
specified.
For the best result, measurements are performed in a straight viewing angle to the
picture tube, e.g. you see into the reflection of your own eye.
Geometry must be checked and adjusted in format
16:9, FORMAT 3
15:9, FORMAT 1
4:3, FORMAT 1 + scroll (optional format)
(3 different set of adjustment data is stored)
The picture tube and the contrast screen must be cleaned after geometry adjustment.
