Calibration
Sometimes there is a need to calibrate the touch panel attached to the display monitor, i.e. to adjust the pushed position of the panel and its display position of the monitor. Even if the touch panel has same dimensions as the display monitor, there may be minor variations between corresponding data points due to resistance variance of each panel.
When you use touch panel module for the first time, or, when there is discrepancy between the touched and displayed positions, calibration is required. This needs to be done only once, whereupon the calibration data is stored. The CPU will automatically calculate the touched position on display monitor.
This adjustment may be executed with the MW800 Display Calibration Tool.
