(3) End point correlation line
TUE=Total Unadjusted Error: maximum deviation
between the actual and the ideal transfer curves.
OE=Offset Error: deviation between the first actual
transition and the first ideal one.
GE=Gain Error: deviation between the last ideal
transition and the last actual one.
DLE=Differential Linearity Error: maximum devia-
tion between actual steps and the ideal one.
ILE=Integral Linearity Error: maximum deviation
between any actual transition and the end point
correlation line.
