21x4 Target... Re: Linearization problem/question

2006-05-22 by edrudolpho

Roy, I did a measurement using the 21x4 target yesterday and noticed that one of the "b" 
values, at about the 85 or 90 step, was way out of line with that portion of the b curve.   
The b values in that area were in the .04 to .08 range and suddenly there was a .5.  This 
was the averaged measurement.  Would you trust that?
