Chapter 9 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.
9.3 Teach Screen
To display the Teach screen, click the Teach button on the Main Menu toolbar, or click the Next button on the Tools
screen Build tab.
Use the Teach screen to automatically set judgment tolerances to accommodate all variations of good product. After
teaching the inspection, typically proceed to the Run screen to run it.
