Secondary Adap-
tive Blob Threshold
Offset
If Adaptive Threshold Method is selected, this offset is added to the
adaptive threshold. This allows you to weight the adaptive threshold up
or down.
Secondary Noise
Level
The amount of background noise present in the image along the Sec-
ondary Wide Line ROI. Higher noise means the edges must be farther
apart. Lower noise allows edges that are closer together.
Secondary Maxi-
mum Number Of
Edges To Find
Limits the number of edges found along the Secondary Wide Line ROI to
those with the strongest transition
Secondary Edge
Pattern
The edge pattern to find along the Secondary Wide Line ROI (Rising
indicates a transition from dark to light; Falling indicates a transition from
light to dark)
Secondary Subpixel
Method
Indicates how many subpixel points to average when finding edge points
along the Secondary Wide Line ROI. More points used provides greater
accuracy but takes more time. See “Subpixel Method” on page 3-125.
Secondary Subpixel
Position
The subpixel position for edges that are not well defined. See “Subpixel
Position” on page 3-144.
Secondary Subpixel
Search Distance in
Pixels
The maximum distance, in pixels, that the subpixel algorithm will search
from the threshold edge for the subpixel edge. See “Subpixel Search
Distance” on page 3-125.
Number of Steps Duplicates the Primary and Secondary Wide Line ROIs. Allows multiple
measurements with one tool.
Step Distance The distance between the measurement steps
Step Angle in
Degrees
The angle of the duplicate ROIs relative the original ROIs (see “Step
Angle” on page 3-125)
Scale Factor The scale factor applied to the output distance. This is applied after any
camera calibration.
Scale Factor Train
Distance
When the tool is trained, this scale factor is calculated so that the mea-
sured distance is scaled to this value.

one.
