Color Match Percent Threshold

The first of two settable parameters for the Color Match tool, the Color Match Percent Threshold, controls the variation
in the colors to be matched in the future.

Increasing this number will reduce the range of colors present on the Acceptable Colors map. When the Color Match
Percent Threshold is set to 100, the map of Acceptable Colors will include only one hue. If this threshold is reduced
to 0 the map of Acceptable Colors will start to look more like a rainbow, including a large number of hues. A typical
setting for this threshold is around 90.

Intensity Match Range

As the Color Match Percent Threshold defines the specific hues which can be considered good, the Intensity Match
Range defines the grayscale brightness level necessary to constitute a match. This value ranges from 0 to 255.

As the Tolerance value is changed, the acceptable Min and Max limits on either side of the Reference are calculated.
When the number is set to 255, a full range of color shades are displayed on the map of Acceptable Colors; starting
with black on the left and continuing to the fully saturated color on the right. When this tolerance is set to 0, only a
single shade of each color is acceptable; that is, no change in the amount of black present in the color is allowed. Or,
to say it another way, no changing the intensity of illumination for a given color target is allowed.

Enabling Remote Teach

The Remote Teach function is a method of remotely updating inspection parameters in Run mode. Vision tools and
Test tools can be selected to be taught or not taught. To remotely teach an inspection, the Remote Teach function must
be enabled on each tool to be taught.
