Parameter Description
Skip A percentage of the profile point heights in the histogram,
starting from the highest points, to exclude from the
average.
The Skip setting basically sets the upper limit of the profile
point heights in the histogram to be used in the average.
Use the setting to exclude higher parts of a profile that you
do not want to include in the measurement.
If Skip is greater than Window , an invalid value is returned.
Max Invalid The maximum percentage of invalid points allowed before
an invalid result is returned.
Max Differential The maximum difference between the maximum and
minimum histogram values before an invalid measurement
value is produced.
Normalize Tilt Fits a line to the profile and shears the points in the Z
direction by the angle between the fitted line and the X
axis. The Window and Skip settings are applied to the
histogram of the transformed data.
Useful for surfaces that are tilted.
Region The region to which the tool's measurements will apply. For
more information, see Regions on page 184.
Filters The filters that are applied to measurement values before
they are output. For more information, see Filters on page
192.
Decision The Max and Min settings define the range that determines
whether the measurement tool sends a pass or fail decision
to the output. For more information, see Decisions on page
191.
Anchor Description
X or Z Lets you choose the X or Z measurement of another tool to
use as a positional anchor for this tool.
Anchoring
A measurement must be enabled in the other tool for it to be available as an anchor. The anchor
measurement should also be properly configured before using it as an anchor.
For more information on anchoring, see Measurement Anchoring on page 194.
Using Window and StdDev as Metrics Measurements
When a tracking window is defined, if the profile moves too quickly out of the tracking window and there
is excessive noise in the scan data (caused for example by ambient light), the tracking window may track
