Calibrating the Touch Screen

This chapter describes the calibration process for the EXPC-1319 touch panel.

First, Open the PenMount control panel. This may be found under the Windows 7 Start Menu, in the

Programs list in the PenMount Windows Universal Driver(WHQL) folder. From the PenMount folder,

navigate to the Utility folder and open the PenMount Control Panel.

Next, the PenMount Control Panel should appear as in the screen shot to

the right, with the Device tab as its default display. Double-click on the

device you want to calibrate, or select the device and click Configure. If you

do not see your device offered on the menu, click Refresh to refresh the list.

The final preparatory step is to choose what sort of calibration you

want. Most will choose Standard Calibration, which is a basic touch

screen calibration using five reference points. For most situations, a

standard calibration should be adequate. As the touch screen ages,

users will find that the standard calibration is not adequate for

re-establishing screen accuracy and precision. If problems are still

encountered following a standard calibration, you may choose

Advanced Calibration to calibrate the touch screen to a greater

number of reference points.

Standard Calibration

For a standard five point calibration, five spots will appear one

after another on the display. Use your finger or stylus to touch

the five points in order. After you have completed the

sequence, hit ESC on your keyboard to save the result and

exit the calibration process.

Advanced Calibration

An advanced calibration uses 9, 16, or 25 points to calibrate

touch panel linearity; select the number of reference points

from the drop-down menu offered on the calibration utility

main dialog. You may also instruct the calibration utility to

plot detailed calibration data onto a graph. For more

information about the data graph, see the next section,

Calibration Data Graph.

Just as with the standard calibration, to complete the

calibration use your finger or stylus to touch the points in

order, as they appear. After you have completed the sequence, hit ESC on your keyboard to save the result and

exit the calibration process.
