11) It pays attention to the horizontal line of EXCEL.
A Focus is made to get fat with VR, and some double horizontal lines are displayed.
Adjust within the limits of value of VDF(±10STEP) so that the horizontal line double pallet width of 4
square of center and top and bottom may become the same.
Adjust within the limits of value of HDF(between 210±20 STEP) so that the horizontal line width of 4
cell of center and left and right may become the same.
Note: Double horizontal lines is done as the one for the center is a little opened because both
differences become ambiguous when it is displayed too much. And because it becomes over-
revision, it is faced a little inside at the edge of the screen.
12) Adjust Focus VR F2 so that character vertical wire of EXCEL may get clear thicker.
13) Adjust Focus VR F1 so that horizontal is not double line and characters are fine on all area.
14) Receive signal 31("ヨ" character) by BNC input, and "CONTRAST" and "BRIGHTNESS" are adjusted
to PRESET in the user menu.
15) Make sure that the horizontal lines of "ヨ" character white and green colors are crisp as possible in the
whole screen. (It is confirmed by using a magnifying glass of 10 times.)
a) The space between horizontal lines is crisp.
b) The horizontal lines are not bold, and do not form halo
When it isn't missing, it is adjusted again about 12), the 13) clause.
16) Receive signal 33. (Cross-hatch,Red/Green/Blue each color) Make sure halo is within the specification.
Vertical line halo: halo and core of red and blue color <= 9
halo and core of green color <= 8
Horizontal line halo: judged to be level (core / halo: 1/1)
