5. Horizontal Raster position adjustment
1) Adjusting V/R: no adjustment
2) Adjusting position: center of screen
6. Check of coordinates value
1) Adjusting position: center of screen (measured as CA-100 in CRT face)
2) Measuring condition: After adjusting Back Raster into 0.1F/L by varying of
screen at Cross Hatch, measurement is made at max 70F/L in Window pattern
