On the XDS instrument, Vision asks if the user
wishes to use an external sample (standard) for
the test. Click “Yes” to use an external 10%
reflectance standard.
When doing the Low-Flux Test on non-XDS
instruments the following window will appear.
The 10 % reflectance standard should be
positioned and the test runs.
If the user clicks “No” to the external standard (on the XDS only), then Vision will automatically
trigger the 10 % internal screen for this test. No user action is required. Vision runs the Low-Flux
Test, which takes about 20 minutes. At the end, the results are displayed.
Results from a typical run are shown:
In the tabular result in the lower right quadrant
of the screen, click on the tab marked
“Summary” to see the summarized results as
compared to acceptance specifications. Vision
reports a pass or fail based upon successful test
completion. Results are stored in the Diagnostic
Database for later recall. The user may print
results, or click “Close” to complete the test.
