The spectrometer can be aligned automatically using OMNIC software. Alignment optimizes
the energy throughput to the detector. Alignment can change slightly over time, particularly
in locations that have large temperature swings or excessive vibration.
 To align the spectrometer
1. From the OMNIC software main screen, choose Collect > Experiment Setup.
2. Select the Diagnostic tab and click Align.
For more information, see OMNIC Help Topics in the Help menu.
Note The spectrometer is aligned automatically each time you run a Performance
Verification (PV) test. We recommend running a PV test at least once a month.
