= 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.
