13.9 Configuring a Color Area Sensor
1. Begin the setup with a good part.
2. Center the part to be tested in the Field of View (FOV).
3. Adjust the Region of Interest (ROI) so that it surrounds the feature of interest. In the Demo example, the feature of
interest is the pink text, "iVu Color".
4. Click the [Sensor Name] to open the sensor parameters menu.
Figure 134. Open the Parameters Menu
5. Set the sensor parameters.
• Select the Color Select.
Use Color Select to select the color the Color Area sensor looks for. Click
Color Selector then click the
desired color in the ROI. Adjust the color tolerance using + and -.
Note: You can select a color that is outside of the ROI, but a BLOB of that color will only
be detected within the ROI.
In the Demo example, the desired color is pink.
If needed, zoom in to better select the desired color.

After the color is selected, + and - buttons display. Click these buttons to fine-tune the selection.
• Adjust the Area Range.
Use Area Range to set the size limits of a feature of interest. Move the slider to select the range. Areas are
measured by counting pixels. For example, a rectangular feature that is 100 pixels wide by 200 pixels tall
has an area of roughly 20,000 pixels.

In the Demo example, the Area Range is 29 – 782.
