5.3.4 Reverting to Instrument Calibration
The Revert to Instrument Calibration function does the
following:
• Mariner data—Reapplies the original calibration
constants used to acquire the data.
• Voyager data—Applies default calibration to the data,
regardless of whether default or external calibration is
used to acquire the data.
To revert the calibration:
1. From the Process menu, select Mass Calibration, then
select Revert to Instrument Calibration.
The spectrum is recalibrated with the original
calibration constants used during acquisition (Mariner
data) or default calibration (Voyager data) and
displayed with an MC trace label. The original and new
constants are displayed in the Output window.
2. To save the reverted calibration with the data file, select
Mass Calibration from the Process menu, then:
