16 5.4 General Teach Information Once an output is taught, the mean and SD for the Sort Output are immediately stored in the color sensor (overwrit

17 5.5 Saving Teach Data Using the Sort Editor screen in the ColorSense program, Teach data can be uploaded from the sensor, downloaded to sensor,

18 6. ColorSense Program Main Screen The main ColorSense screen has a large window for all of the sub-screens and a menu bar across the top. To get

20 Error Limit: This parameter allows you to specify a maximum permissible error for a color to be considered a match. The default value is 5,000.

21 7.4 CS24D Options Summary In addition to the Setup Wizard, options can also be viewed and changed using the Sensor Options screen under the Se

22 8. Optimizing Performance The CS24D analyzes four values: red, green, blue, and intensity. The intensity value is used directly, and the blue,

23 With some sorting modes, a second criterion is used to further refine the performance. A limit to the maximum Error, called the Error Limit, ca

24 8.3 Optimizing using the Analyze screen The Analyze screen shows the predicted performance for the Teach data, which is shown as the number of st

25 8.4 Graph and Sort Error Tools The Graph screen shows each color in the Teach data drawn together on a graph. This helps to visualize difficult

26 8.5 Averaging and Response Time Since the internal signals used by CS24D can be fairly weak (especially with dark target colors), they are sub
