Perform a step test.
1. Press the [Step] button at the "Tuning" tab to perform a test for the created step.
Test results and detection data are displayed when testing is complete. When doing so, there is no
problem if the test result is "NG".

Detected data
dx =, dy = : These are offset amounts for which position correction was performed.
Level = : This is the measured luminance level.
2. Take a note of and check the detection data, and then press the [End] button.
5
Set the "Brightness Level" in the judgment conditions parameters.
Refer to the detection data "Level" and set the "Min Luminance Level" and "Max Luminance Level".
Min Luminance Level
Select a value smaller than the detection data "Level" from the drop-down list, or enter a value directly.
Max Luminance Level
Select a value greater than the detection data "Level" from the drop-down list, or enter a value directly.

Perform a step test again.
1. Press the [Step] button again to perform a step test.
2. Take a note of and check the detection data, and then press the [End] button.
3. If the test result is not judged correctly, review all parameters while referring to the detection data.

1.9 Comparison
This inspection status is used to inspect polarity and so on based on whether the difference in luminance
between two locations lies within the standard range. Three steps are set for comparison inspection, with
luminance measurement performed first at a bright location, and then at a dark location. Finally, the difference
between the two luminance values is calculated, and a judgment is made on whether the value lies within the
standard. The following description takes a luminance difference comparison as an example, however, the
same settings should be specified even when inspecting differences in thickness with the YSi-X.

NOTE
If specifying settings for comparison with the YSi-X, thickness is measured at two locations with similar settings, and
finally, the difference between the two thicknesses is calculated to judge whether the value lies within the standard.

Set the "LIGHT" parameters.
1. Open the "LIGHT" tab and select "Luminance" at "Light Sampling Type".
2. Press the button to the right of the sampling light value field to open the sampling light list, select
"Mb+Lb" from the list, and then press the [OK] button.

Create a "step" on the dark side.
1. Select the step created at Step 1, and then copy and paste the step.
2. Move the pasted step to the position when the part is rotated 180°. Select the step, right-click, and
open the context menu. By selecting a "Step rotation" of "180°", the step moves to the position when
the part is rotated 180°.

Set the "Memory No." in the judgment conditions parameters.
Select a number other than the number set at Step 3 from the drop-down list. "2" is selected here.

Create a comparison step.
1. Select the step created at Step 4, and then copy and paste the step.
2. The frame of the pasted step is changed to a different shape in order to distinguish it from the
luminance level steps, and then moves close to the two luminance level steps.
