On rare occasions the system fails to recognize the triangle even though it is in the
data set. The system might also make a determination that one of a number of
detected features is the correct one. To determine if the triangle is in a given data set,
review the scan data set of detected features at the bottom left of the Scan Offset
Calibration Analysis portion of the screen. If the triangle is present then the scan
calibration can be reset.
1. Click on the scan feature data set that represents the triangle so that it highlights.
In
Figure 13.35 the system choose feature number 1 and set its parameters in the
Up Edge and Down Edge fields. (See Figure 13.35 .) However, feature number 2
is 151.71
μ
m which is very near the expected scan distance of 150
μ
m. In this
example the user would click on that feature to highlight it.
2. With the feature highlighted, click on
Set
to choose that feature as the triangle.
The Up and Down parameters of the data set are recorded in the Up Edge and
Down Edge fields. (See
Figure 13.35 .)
