8.3 Measuring procedures
8.3.1 Principal procedures in contour analysis
Digiset 5 has two main measuring procedures that are used for analysing an object
contour.
•
Point measurement
•
Line or angle measurement
8.3.1.1 Point measurement
Point measurement determines the highest deviation value in the corresponding axis.
This is done in the "Fixed axis" measuring method by moving the object to be meas-
ured to the corresponding cross hairs axis so that the adjustment bar pointer is in the
green area.
In the "Maximum" and "Preset" measuring methods Digiset 5 automatically calculates
the highest deviation position and creates the red measuring lines vertically or hori-
zontally.
8.3.1.2 Line or angle measurement
Line measurement determines and analyses one or more of the object’s straight con-
tour sections.
In the "Fixed axis" measuring method, red lines which pass through the cross hairs
origin point are drawn parallel to these contour sections and their angles to the cross
hairs displayed. The distance of the object to be measured from the red measuring
line(s) is indicated by the adjustment bar pointers.
In the "Maximum" and "Preset" measuring methods the red measuring lines are
placed directly above the object’s straight contour sections. The imaging results and
the current position of the optical equipment carrier are taken into account together.
