Probing part features
Part features can be probed with crosshairs or with optional optical
edge detection. If optical edge detection is used, points can be
entered manually or automatically.
Probing with crosshairs
U
Move the stage to position the crosshairs over the desired feature
point and press the ENTER key. The probed point will be added to
the points required for the feature.
Probing with optical edge detection
Probing with optical edge detection speeds the measurement process
and increases measurement consistency. Two general guidelines
should be followed when probing with optical edge detection:
Move the stage to make edge crossings as close to perpendicular
as possible.
Move the stage at slow to moderate speeds when possible. In
general, slower edge crossings are slightly more accurate.
To probe with edge detection:
Skip these probing instructions if your ND 1200 does not
include the optical edge detection option.
U
Move the stage to pass the optical sensor over the edge.
U
When manual point entry is used, the ND 1200 will beep when an
edge is recognized. Press the ENTER key to add the point to the
number required for the measurement.
U
When automatic point entry (Auto E) is used, the ND 1200 will beep
when an edge is recognized and will add the point to the number
required for the feature measurement automatically.
