Comparison Measurement
Comparison measurements rely on the known dimensions of an object
that have been set in the field of view either by the manufacturer or
by the probe. The XL Vu processor uses these known dimensions
as a reference scale for measuring an unknown target. Comparison
measurements can be taken on a frozen image or on a recalled image.
Positioning the Probe Tip for Maximum Accuracy
Position the probe view so the surface is perpendicular to the probe.
Target and known object should both be in the same view and plane.
Position the probe tip to be as close to the target as possible.
Taking Comparison Measurements
1.
Attach any standard forward-view or side-view tip to the probe.
2.
Position the probe tip for maximum accuracy.
If the object and reference are small on the screen, zoom until
the known object and the target fill the screen as much as
possible.
3.
Freeze the image.
4.
Select the measurement type.
5.
Establish the reference distance.
Place the two reference cursors at the endpoints of a known
distance. Then adjust the displayed number until it matches
that distance.
6.
Place the cursors for the feature or defect to be measured.

7.
(Optional) Reposition the cursors and measurement result.
8.
(Optional) Perform any of these tasks:
• Add measurements, up to five total.
• Clear some or all measurements.
• Establish a new reference dimension.
9.
Save the image.
