SIGMA LBA-708 - Manual (Page 99)

3.3.1.1 PASS or FAIL results
The remaining Pass/Fail dialog boxes are used to set the Pass/Fail limits for the results items
that you want to test and screen for. When you check an item, you turn on the Pass/Fail
screening for that particular result. At the same time, you change how that result item will
appear in the results window. If a results item is being tested and it fails the test limits, the
displayed color will appear RED ; if it passes the test limits, it will appear in GREEN .
3.3.1.2 Pass/Fail Units
The test units are always the same as what appears in the results window. If you redefine the
results window units, the set Pass/Fail values will not automatically rescale to the new settings.
In this case, you must manually change the Min. and Max. limits to meet the new unit
requirements.
3.3.1.3 Pass/Fail dialog boxes
The remaining Pass/Fail dialog boxes are very similar in how they allow you to select and set
limits for the result items that you want to test. In each instance you must:
1. Enable the results item by checking on its selection box.
2. Set the test limit values that are required.
In some instances you can select either or both Minimum and Maximum test limits.
Pass/Fail testing can only be performed on Current frame results. No Pass/Fail testing is allowed for Statistics
results.
Pass/Fail testing can only be performed on computational results that are enabled in the Computations dialog box.
Most of the Pass/Fail dialog box edit control items are obvious in their meaning, and how to set
them up. A few items are less obvious and are explained in the following sections.
3.3.2 Quantitative Pass/Fail
The following results may be set in the Pass/Fail Quantitative… dialog below the main menu
Pass/Fail item.
3.3.2.1 Min Fluence
The Min Fluence test is performed on the Min value in the Quantitative results display. This
test is best applied in conjunction with a manually Drawn Aperture. It can be used to test for
a Minimum fluence range of values over a specified region of your beam.
If your beam is a Top Hat, don’t use this test. Use the Top Hat Fluence setting in the Top Hat
Pass/Fail dialog box.
