Testing the Calibration
After you calibrate the touchscreen, test the calibration as follows:
Touch the center of the screen and check that the cursor is located
underneath your finger.
Drag your finger across the screen and check that the cursor
follows your movements.
Move your finger to each corner and edge of the screen. Check
that the cursor follows your finger and reaches the edges of the
screen image.
If you cannot reach the edges of the video image or the cursor is not
located underneath your finger or pen, recalibrate the screen.
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 example, if you
touch beyond the targets or into the black non-image area, you will
distort the touchscreen calibration.
You can calibrate the touchscreen by using the Calibrate option in the
Touchscreen Control program or in the Microcal utility. For more
information about using the Touchscreen Control program, refer to
Chapter 2. For more information about using Microcal, refer to
Chapter 4.
If you are still having problems with the cursor movement, you may
need to adjust the touchscreen controller frequency using Microcal.
For more information about adjusting frequency, refer to Chapter 4.
