The recommended scan speed for the scan speed compensation is 1000 amu/sec. This
is the maximum scan speed permissible when using thresholded continuum data.
Although continuum is recommended centroided data may be used. It is possible
to scan more quickly in centroided mode, but it is unlikely that a faster
acquisition rate would be needed for general use.

The filename FASTMS1, the name used during an automatic calibration, is
valid.
Start the acquisition and inject the reference solution.

Find the start and end scans of the reference data for each file in the same way
as for the static calibration file.
From the Calibration dialog box select

calibration type and
MS1
.
In the lower area the data filename
SCNMS1
should be selected automatically.
If this is not the case, or if an alternative filename has been used for the slow
scanning acquisition, then the correct file can be selected by clicking on
Browse...
.
Enter the start and end scans of the reference data in the
From

Select
OK
to perform the calibration and display the calibration report on the
screen in a similar way to the static calibration.
Compare the acquired and reference spectra to ensure that the correct peaks have
been matched.
