Landing Adjustment
1
Turn the front panel BRIGHTNESS control fully clockwise.
2
Degauss the CRT by momentarily pressing the DEGAUSS switch located on the
instrument rear panel.
In some cases, the user’s environment or shipping environment may have caused high levels of
magnetization in the CRT. In this case, to completely degauss the CRT you may need to use a
conventional television-type degaussing coil.
3
Set the purity magnet tabs to the mechanical center. Refer to the next figure.
4
Display a green raster test pattern on the display.
From the Color Display Test menu, select the green raster.
In the next steps, while moving the deflection yoke forward and rearward, rotate the yoke as
necessary to keep the edges of the raster parallel to the sides of the display.
6
Move the deflection yoke rearward until the left edge of the raster turns red and the
right side of the raster turns blue.
7
Adjust the purity magnets until green is in the center of the raster with red and blue
bands evenly distributed on the sides.
