• Auto label position – puts the label (LOC1) beside the position anchor in the display. Clear the

to add image filtering, or feature enhancement. Adding
preprocessing may increase inspection time. Please refer to page 15.
g. Click the “check” button
to accept changes and close the Locator Properties box. Click
the X button
to close without changes.
Defining a Locator
• For best results, the two features should be as far apart as possible. Opposite sides or opposite
corners are best to calculate angular change (rotation). If the two features are very close, the
rotation will be hard to identify.
• For any tool used by the locator, the search box or search area must be expanded to include all
expected movement.
• The Match tool is generally best for use with the Locator. This tool searches a defined area for a
pattern and snaps to that pattern’s location. Other tools may be usable or even better suited,
depending on the features in your particular part or image, and the amount of movement. The
Distance Tool and Angle Tool are not suggested for use with the Locator.
Some Locator examples are included in this manual starting on page 108.
Using the Origin
The axis origin, or point (0,0) can be relocated by clicking in the image area.
• The origin will “snap” to (attach to or lock onto) the top left and bottom left corners of the
image area.
• The origin will “snap” to the position anchor of a locator.
• The origin will snap to a point on an edge.
• The origin cannot be located on a measurement tool, or the active point of a measurement tool
(except for the Locator and Point).
