or stylus.
3-Point Calibration - Quick calibration of a known good touch screen overlay.
No correction is applied.
4-Point Calibration - Compensates for skew, and some edge linearity anomalies.
7-Point Calibration - Provides a more accurate calibration than 3-point. No
correction is applied.
20-Point Calibration - Provides the highest level of touch screen linearization and
skew correction.
Calibration Offset - Because of the varied linearity that exists between touch
screens, you may want to calibrate the edges of the touch screen more precisely.
Experiment with this setting to find the best result.
your touch screen as accurately as possible. Make sure to touch the center of
each target as accurately as possible.
Panel if the first point is not touched within 10 seconds.This is a time-out feature
that has been added to the calibration program.
If the target appears directly under your finger, click the “Accept” button. If the
target does not appear directly beneath your finger or stylus, click the “Cancel”
button, reconfigure your calibration options, and recalibrate until you get an
acceptable calibration.You may adjust the “Offset, ” or try the 4-point and/or
20-point calibration.
