6 Calibration and Operation
6.1 Touch Screen Interface
6.1.1 Introduction
The integrated touch screen uses 5-wire hardened resistive technology that provides long time
use without the need to recalibrate. The touch screen can be manipulated with either a finger, a
glove, or a stylus. The hardened resistive glass provides exceptional resistance to scratches,
impacts, chemicals, and excessive heat.
6.1.2 Touch Screen Calibration
The VisuNet XT touch screen is factory-calibrated and uses factory-installed Elo touch screen
software. Calibration\Alignment of the newly installed touch screen should not be necessary.
However, over a period of time the alignment points may wander slightly and you may notice
the cursor does perform properly. This is a good indication that touch screen calibration may
be necessary to realign the screen. As a rule of thumb, it is recommended that you calibrate
the touch screen if the cursor is more than 0.25 inch from the exact center of the point of touch.
Doing this will increase the accuracy of touch response and make it easier to touch objects
with pinpoint accuracy.
An Elo Touchsystems icon can be found on the computer’s desktop or in the taskbar, and in
the control panel. See Figure 6.1 .
