Display Geometry Test
This test is not necessary for the operation of the touch screen.
The Display Geometry Test enables you to check the linearity and geometry of the
display. To begin the test, touch the GEOMETRY touch key on the Test screen,
or press
Shift/2 on the keyboard.
The Display Geometry Test provides a pattern so you can see how straight the
lines and how square the corners of the display are. In a well-aligned display, lines
are straight and uniform within the area provided for them on the display.
The test remains active until the Setup key on the keyboard is pressed or the Setup
switch is touched. This returns the terminal to the Test screen.
