Types of 3D Phase Measurements
This section specifically addresses cursor placement for each type of 3D Phase Measurement.
Description:
Linear (Point-
to-Point)
measurement
Cursor Placement:
Place both cursors at the
desired locations.
Description:
The perpen-
dicular distance
from a point to a line.
Cursor Placement:
Place the first two cursors
to define a reference line.
Place the third cursor at the
perpendicular distance you
want to measure.
Description:
The perpen-
dicular distance
between a surface and a
point above or below it.
Used to evaluate changes
due to wear, misalignment,
and other causes.
Negative measurements
indicate that the point lies
below the plane. Positive
measurements indicate
that it lies above the plane.
Cursor Placement:
Place the first three cursors
to define a reference plane.
Place the fourth cursor at
the perpendicular distance
you want to measure.
Note: Depth measurements
require the closest possible
tip-to-target distance for
the greatest accuracy.
Description:
The surface area
contained within
multiple cursors placed
around a feature or defect.
Cursor Placement:
Place three or more cursors
(up to 24) around the edge
of the area you want to
measure.
When finished, press
twice. The area
closes.
Description:
The length of a
nonlinear feature
or defect.
Cursor Placement:
Place two or more
measurement cursors (up to
24) to create line segments
along the feature.
When finished, press
twice. The line is
finalized.
Description:
A profile of the
perpendicular
distances from an area
of interest to a specified
surface.
Cursor Placement:
Place two measurement
cursors on a flat surface
adjacent to the area of
interest to create a reference
plane
When finished, press
and hold to display the
depth profile view.
(See the following section for
more detail)
Note: Depth Profile
measurements require the
closest possible tip-to-target
distance for the greatest
accuracy
