3-14 Chapter 3: Installation
Calibration Using Microcal (DOS)
The calibration program looks at where your finger is when you lift it
off the screen, not where you touch it. Therefore, calibrate the screen as
follows:
1. Touch the screen near the calibration target.
2. Keep your finger on the screen and slide it to the center of the
target.
3. Hold your finger firmly on the target for two seconds, then lift it off
quickly.
4. Verify that the calibration was set accurately before making a
service call. Perform the calibration again if necessary.
If cursor is not stable, or false touches are suspected, run the Noise
Check Utility from the Microcal program. Choose the recommended
frequency (the one with the lowest noise level). This should also be
done if the Touch Screen is still not calibrated after one attempt to
recalibrate it.
1. Set the video resolution by going to the Tools menu, Video and
selecting 800 x 600 256 colors.
2. Go to the Tools menu, select Noise Check.
3. Follow the instruction prompts. Choose the frequency with the
lowest noise level.
Application software can possibly generate a dialog box from the
Touch Driver, with the message that the touch screen needs to be
recalibrated. If the screen appears to be working normally, then this
message can be ignored. There will be a check box labeled Do not
show this message again. Make sure this box is checked.
