=Total Unadjusted Error: maximum deviation between the actual and the ideal transfer curves.
=Integral Linearity Error: maximum deviation between any actual transition and the end point correlation
=Differential Linearity Error: maximum deviation between actual steps and the ideal one.
=Offset Error: deviation between the first actual transition and the first ideal one.
=Gain Error: deviation between the last ideal transition and the last actual one.
