the spectra that have so far been acquired.
•
Average latest scans updates the display with spectra formed by averaging
the last n scans acquired, where n is specified in the associated edit control.
Instrument Data Thresholds
MassLynx has several parameters that allow control over how the system
pre-processes data before it is sent to the host computer. These parameters are
contained in the instrument data thresholding dialog.
Instrument data thresholding allows the user to specify the type of data to acquire and
write to disk, and the type of data to discard and not write to disk. Limiting the
amount of data stored on disk can be particularly desirable when acquiring continuum
data and doing long LC runs.
To change data thresholding:
Choose
Set Instrument Threshold
from the tune page
Options
menu.
Make the required changes to the information.
Press OK .
These new parameters are downloaded at the start of the next acquisition scan.
