Probes
Simple probe
The simple probe acquires a single point each time it is fired. The simple probe uses video edge
detection and consists of a single scan line.
The simple probe can be used to acquire points for most feature measurements and is useful when there are
space constraints or the part geometry makes it difficult to use a larger probe to acquire many points.
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 a point,
use Measure Magic or
select a feature mea-
surement, select and
position the probe and
then click the center
mouse button to fire
the Probe.
The simple probe can be created quickly in the live video
window by clicking and dragging the New probe across the
edge to be scanned.
When the New probe creates a Simple probe, the edge
order will automatically be made consistent with the scan
direction. In this example, the edge order and scan direc-
tion are light to dark.
The simple probe is used to measure a slot where 5 single points are required and
edge detection is not possible
