With the Multi-touch calibration in the self-check function, the touch panel is
automatically calibrated using the results of touches to the top left and bottom right
positions.
The values of “EVR_X”, “EVR_Y”, “X_MAX”, and “Y_MAX” are used for internal processing.
They do not indicate the positions or distance of the touched points. There is no problem unless
there is a huge difference between the values of the first calibration and the second calibration.
