the result data, the orientation error is within the limit of approximately 0.2-
0.5 mm. Fig.36 shows the mean square error of the independent measurement
taken eleven times for the same points on the tire. From these observations, the
range of the observation errors exist within the limit of +0.3 mm. An operator with
ordinary trained skill is capable of taking measurements with similar accuracy.

4.2 Orientation Accuracy of the Compressed Wide Flange
In the wide flange experiment, as shown in fig. 37, the rule of AB and the plumb
line of E regulate the fundamental plane and the scale of the measurement and as 0)
the origin of the co-ordinate, A point, that is the end point of the rule AB, is selected
