Table C.1 IntelliTouch Touchmonitor SpecificationS

Mechanical

Positional Accuracy	Standard deviation of error is less than 0.080 in. (2.03 mm). Equates to less
	than ±1%.
Touchpoint Density	More than 100,000 touchpoints/in2 (15,500 touchpoints/cm2).
Touch Activation Force	Typically less than 3 ounces (85 grams).
Surface Durability	Surface durability is that of glass, Mohs’ hardness rating of 7.
Expected Life	No known wear-out mechanism, as there are no layers, coatings, or moving parts.
Performance	IntelliTouch technology has been operationally tested to more than 50 million
	touches in one location without failure, using a stylus similar to a finger.
Sealing	Unit is sealed to protect against splashed liquids, dirt, and dust. See IntelliTouch
	Product Manual for details.
