Linearity Maximum difference
(Vertical) between the intersection
(Defined by point of the vertical line B
1st Gene.) and each horizontal line,
IIT
and the line that passes at
P10 and P12.
Linearity Maximum difference
(Horizontal) between the intersection
(Defined by point of the horizontal line
1st Gene.) C and each vertical line, and
the line that passes at P10
and P15.
Linearity Maximum difference
(skew) between the intersection
(Defined by point of the skew line D and
1st Gene.) each line, and the line that
passes at P17 and P13, or
maximum difference
between the intersection
point of the skew line E and
each line, and the line that
passes at P8 and P18,
whichever larger.
Perpendicularity Difference between the per-
(400 mm) pendicular line of the inter-
section point between the
line that passes at P4 and P6
and the line A, and P14.
