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.
