AccuTouch Touchmonitor Specifications

M echanical

Construction	Top: Polyester with outside hard-surface coating
	with clear or antiglare finish.
	Inside: Transparent conductive coating.
	Bottom: Glass substrate with uniform resistive
	coating. Top and bottom layers separated by
	Elo-patented separator dots.
Positional Accuracy	Standard deviation of error is less than 0.080 in.
	(2.03 mm). This equates to less than –1%.
Touchpoint Density	More than 100,000 touchpoints/in† (15,500
	touchpoints/cm†).
Touch Activation Force	Typically less than 4 ounces (113 grams).
Surface Durability	Meets Taber Abrasion Test (ASTM D1044),
	CS-10F wheel, 500 g.
	Meets pencil hardness 3H.
Expected Life Performance	AccuTouch technology has been operationally
	tested to greater than 35 million touches in one
	location without failure, using a stylus similar to a
	finger.
Optical
Light Transmission (per	Typically 75% at 550-nm wavelength (visible light
ASTM D1003	spectrum).
Visual Resolution	All measurements made using USAF 1951
	Resolution Chart, under 30 X magnification, with
	test unit located approximately 1.5 in. (38 mm)
	from surface of resolution chart.
	Clear surface: N/A
	Antiglare surface: 6:1 minimum.
Haze (per ASTM D1003	Clear surface: Less than 1.5%.
	Antiglare surface: Less than 15%.
	Clear surface: N/A
