Teach
The inspection parameters can be taught automatically by using the Teach function. There are two Teach options:
Quick Teach and Teach. The Quick Teach button is in the Tools window, and the Teach button is in the Main Menu
toolbar.
9.1 Quick Teach
Use Quick Teach to set the Pass/Fail parameters based on the reference image. This is a fast way to start
inspecting products with minimal effort. This method works best when the reference image is a good
representation of all the parts. If the good parts can vary in appearance, standard Teach is a better option.
Click the Quick Teach button to trigger the following events:
1. The results calculated from the reference image are transferred to the minimum and maximum
fields in the Test tool.
2. If a tool’s Results field includes a tolerance (e.g., shortest distance), then the additional tolerance
is calculated (default is 10%).
3. The Save window prompts the user to save the inspection on the Sensor.
4. The software proceeds to the Run screen.
Caution: Quick Teach will overwrite all the minimum and maximum values in the Test tool. If
values were entered manually, or no changes are desired, go directly to Run without clicking
Quick Teach.
9.2 Teach
Use Teach to automatically set the Pass/Fail parameters based on a sample of good parts. Instead of using
the reference image as the good part, Teach uses new good parts that are presented to the sensor under
running conditions.
Note: The Teach screen looks very similar to the Run screen. Verify that the sensor is at the
Run screen and not the Teach screen before running an inspection.
There is no limit to the sample size during the Teach process. Teach will only expand the parameter window.
If the current tolerances were greater than the sample set shown during the Teach process, then the Sensor
will retain the old tolerances. Use Teach when there is a large part variation between the good parts.
Caution: Only use good parts with Teach. A taught bad part will pass the inspection.
