Control Centre window
Each tab groups a set of adjustable instrument parameters and
associated system readings.
Each adjustable parameter is displayed with a value and slider bar.
Each parameter can be adjusted in one of three ways:
By typing in the required setting and pressing Enter.
By clicking on either the left or right arrow to change to a lower
or higher setting respectively.
By dragging the position indicator along the adjustment bar.
Several tuning regimes can be configured in which different “sets” of
tuning settings can be grouped. In practice there is a “default” tuning
regime for all masses above a certain cut-off in the range of 5 to 19
and a “low resolution “tuning regime for all masses below this cut-
off.
The first tab is by default Emission. This tab allows the following:
Switching the filament on and off.
Changing the selection of either filament 1 or filament 2.
Adjusting the trap current.
The Peak Shape tab displays the ion intensity over a defined mass
window (
).
