Multiple threshold value settings
If there are differences in inspection object luminance due to differences in part lots, inspection can be performed by
setting four different threshold values for a single step.
1. Press the "LIGHT" tab at the [Data Edit] - "Step" screen.
2. Set "Thresh 2", "Thresh 3", and "Thresh 4" to "Use" only for the number of set threshold values.
3. Use the threshold value setting bar to display only the inspection object in the step screen in red.

Set the threshold value.
1. Press the [Sampling] button.
2. Click the location to be detected in the upper left image. The location with same color as the
clicked location is shown in red. When a large area of the part being sampled turns red, press the
[Sampling] button again to end sampling.
3. Press the [Detected] button to verify the area sampled and shown in red in the upper left image.
4. Move the three threshold slide bars to adjust the threshold value until only the inspection object is
shown in red. The area shown in red with Green Ratio, Red Ratio, and Luminance images is shown in
red in the upper left of the image.
