Probes
Buffer Probe
The buffer probe uses edge detection to acquire many points along an edge each time it is fired.
The default of 50 points can be changed by supervisors, distributors and OEMs in the Probe
Library.
The buffer probe can be used to acquire points for line measurements, and can be fired once or multiple
times on a single edge.
Select the probe from the Probe menu, the live video window on-screen menu or the VED toolbar. Move
the probe, change its size or change its orientation as described earlier in this chapter.
To acquire points
along an edge, use
Measure Magic or se-
lect a feature measure-
ment, select and posi-
tion the probe over the
edge and then click the
center mouse button to
fire the Probe.
The buffer probe can be created quickly using the
New probe in the live video window by clicking
2 points and dragging the second point across the
edge to be scanned.
When the New probe creates a buffer probe, the
edge order will automatically be made consistent
with the scan direction. In this example, the edge
order and scan direction are dark to light.
