10. Select the Peak Weighting Factor. If the calibration
includes more than two points, you can apply the
following weighting factors to fit points to the curve:
• None—All peaks are weighted equally
• Inverse Width—Narrower peaks are weighted
more than broader peaks
• Height—More intense peaks are weighted more
than less intense peaks
11. Enter Fit Rejection parameters:
• Minimum Peaks to Match—Minimum number of
peaks that must meet the matching criteria for this
calibration to be successful.
• Maximum Outlier Error (m/z or ppm)—Tolerance
within which all matched peaks must fall for this
calibration to be successful.
NOTE: If the software finds fewer than three
matches, the maximum Outlier Error is not
significant. Masses are labeled with the specified
reference masses.
12. Click Save Settings to save the automatic calibration
settings (reference masses, matching criteria, and fit
rejection parameters) as part of processing settings in
the .DAT file.
Saving the .SET
file
If you are preparing Automatic Calibration settings for use by
the Voyager Sequence Control Panel, save the .SET file by
selecting Settings from the File menu, then select
Save Graphic/Processing Settings As.
