Teaching the video probe
A detailed description of video probes is provided by Chapter 4: Chapter 4: Probes.
Video edge detection must be taught (calibrated) to optimize recognition of
the contrast between dark and light levels prior to measurements. Click the
Probe/Teach Video Edge menu item to teach the probe.
You will be instructed to move the Simple probe
over an edge and press OK. You will also be
given the opportunity to select the type of edge
detection algorithm. Click Auto if it is not al-
ready selected, then click OK.
Position the simple probe over an edge oriented
to detect in the light to dark direction, and then
fire the probe. The acquired data point will be
shown by a red cross at the edge and you will be
notified that a point was acquired by the Simple
probe. Click OK to conclude the calibration.
