Emission and EM are the only settings that, when altered, have an immediate
impact on data collection.
The other scan parameters can be changed, but will not affect the data collection
until SET is clicked. Click SET to restart data acquisition using the changed
parameters.
To change Min/Max AMU values, highlight the current value in the appropriate box
and type in the Min or Max AMU value that is desired. Click SET to start collecting
data in the new mass range.
