Main Tab
This tab covers sensor calibration as well as basic support information.
Calibration
The calibration process aligns the sensor with the underlying video. Specifically,
calibration defines the dimensions of the active area of the sensor and locates the center
of the sensor. If the sensor is not calibrated, the active area of the sensor may not be
aligned properly or may be unnecessarily small.
You should calibrate the sensor in the following cases:
• Any time you change the size and position of the video image by adjusting the
horizontal and vertical controls on your display.
• Any time the cursor does not follow the movement of your finger, or does not reach
the edges of the sensor. If you continue to need additional accuracy along the edges,
use the Edge Adjustment tab.
