4.2Calibration
4.2.1 Calibration Options:
Three point calibration: Quick calibration of a known good touchscreen overlay. May be used to evaluate, test or verify actual touchscreen linearity.
No correction.
Four Point Calibration (Default): Will compensate for skew, and some edge linearity anomalies.
Best for general calibration.
Seven Point Calibration: More accurate than 3 point calibration. Helps calibrate screen to the edges.
No correction.
Twenty Point Calibration: Provides the highest level of touchscreen linearization and skew correction. Should be used to get the best possible calibration
May be used to extend the life of a failing touchscreen.
Calibration Offset: Because of the varied linearity that exists between touchscreen types, you may want to calibrate the edges of the touchscreen more precisely. Experiment with this setting to find the best result.
Default is 20%.
Select the large target to calibrate.
4.2.2 Configure Calibration Settings
Generally speaking, the default setting of 4 Point Calibration is quite accurate for most applications. It is recommended the user try this default setting before configuring calibration with a different setting. If adjustments need to be made, use the procedure on the next page:
