Testing the Calibration
To test the calibration:
1. Press F3 to open the Draw program. Microcal displays a list of
keys you can press when using the Draw program.
2. Press the space bar to clear the screen.
3. Test the touchscreen. Check the following items:
Touch the screen. The cursor should be located underneath
your finger or pen when you touch the screen.
Touch various spots on the screen. Verify that the cursor
follows your finger or pen movement.
Press G to display the grid. Draw several horizontal, vertical,
and diagonal lines. Trace the grid lines and compare your lines
with the grid. Look for the lines to be smooth and straight.
Draw to each corner and edge of the screen. Verify that the
cursor reaches the full image area of the screen. Be sure you
can touch and activate all icons and menus across the entire
screen.
If you cannot reach the edges of the image or the cursor is not located
underneath your touch, recalibrate the screen. If you are not satisfied
with the calibration, you can repeat the process.
If any part of the calibration test fails, recalibrate the touchscreen.
Make sure to touch the corners carefully. It is possible that one of
your touches did not register properly, or you accidentally touched the
screen in the wrong place during calibration.
For more information on the keys available when using the Draw
program, refer to “Drawing and Testing” later in this chapter.
