Running Internal Alignments
Running Internal Alignments
Each time the analyzer is powered on, the internal alignment routine runs automatically.
The analyzer was shipped from the factory with the Alignments mode set to Auto. This
setting enables the alignment routine to run automatically either every 24 hours, or when
the internal analyzer temperature changes
±3°C.
NOTE When the Alignment routine runs, you will hear the attenuator settings
changing, which generates noise. This is not an indication of trouble.
Manually Performing an Alignment
If
Auto Align, Off is selected, refer to the Specifications guide for the conditions required to
maintain calibration.
NOTE For detailed information regarding the alignment routine (including how to
run alignments, and how the analyzer can alert you when alignments are
required) refer to the Users guide for your analyzer.
