AccuTouch Touchmonitor Specifications
Mechanical
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 separa tor dots.
Positional Accuracy Standard deviation of error is less than 0.080 in. (2.03 mm). This
equates to less than ±1%.
