4 Points Calibration
Basic calibration can be completed using this utility. Click the “4 Points Calibration” button
to start. The display will change to a white screen with four blinking touch points.

Touch and hold each point until the point stops blinking. If a touch point is not touched within
30 seconds, the utility is closed, returning to the “Touchkit… Tools” dialog box. A progress
bar at the bottom of the screen indicates the time remaining.
Clear and Calibrate
Click the “Clear and Calibrate” button to erase a linearization. This also starts the “4 Points
Calibration” utility. Always use this button if changing from a linearization to a calibration to
ensure the linearization doesn’t effect the calibration.
Linearization
Linearization is another method of calibrating a touch screen. It functions the same way as
the 4 Points Calibration but uses more touch points for finer calibration.
Linearization can be performed using either 9 or 25 points. Select the number of points by
clicking the “Setting” tab and clicking either the “9 Points” or “25 Points” radio button (see
“Linearization Style” on page 3-5).
