Crosshair probe
The crosshair probe acquires a single point each time it is fired. The crosshair probe does not use
video edge detection and is not used in conjunction with Measure Magic.
The crosshair probe can be used to acquire points for most feature measurements and is especially useful
when measuring textured, transparent or other surface features that must be identified by careful visual
inspection.
Select the probe from the Probe menu, the live video window on-screen menu or the VED toolbar. Move
the probe or change its size as described earlier in this chapter.
To acquire a point, se-
lect a feature measure-
ment, and click the
center mouse button to
fire the probe.
Measurement results are sent to the Features tem-
plate and the Results window. The results data
depend on the type of feature measured. Point
measurement results include:
• The feature type and feature number
• The number of points acquired and the number of points used to calculate feature data
• The geometric center location of the feature
• The form value
The crosshair probe is used to measure a circular solder pad that might be more
difficult to measure using edge detection
