Introduction
When the LabView software is running, this window is the
central anchor point around which everything else is
arranged. From here all the other programs and subroutines
can be started, many of which can run simultaneously.
Time Display
The digital time display at the top of this window will
always run when the LabView 3f control is active, no matter
what sub-program you are in. Checking this display is the
fastest way to see if everything is still running.
Buttons for Sub-Programs
The main function of this menu window is (1) to access
all the significant sub-programs and (2) to display which
sub-programs are currently running. After the buttons are
clicked, they will stay "pressed in" until the respective
sub-program quits.

Controls and Analyses
The buttons for the sub-programs are divided into two
groups: controls and analyses. The main difference is that
any and all of the "Controls" can be run simultaneously,
i.e., their windows can be open and active at the
same time. However, only one of the "Analyses" can be active
at any given time. To make this visually clear, all the
other analysis buttons will become dimmed and disabled when
one of them is pressed. It is because of these differences
that a sub-program like "Stability" has been elevated to the
status of "Analysis".
It is possible to run some controls simultaneously
with one of the analyses, but it is not clear whether that
is always a good idea. At any rate, there is a very strict
internal hierarchy in the programs. Whenever one of the
analyses is running, the controls only get "passive"
information about the status of the instrument. For example:
The "Stage" control checks the position of the sample stage
once every second if it is run alone. That means that every
second it is talking to the 3f and inquiring about x and y
positions. However, if one of the analyses is running, it
could mess up a measurement in progress if we would inquire
about the stage position all the time. Therefore, the
controls only get updated information about anything in the
instrument, if the running analysis happens to be using the
same information, too. That means, that it is indeed
possible to watch the current magnet settings and EM
readings in the "Main" control during a measurement, but you
will only see the same information that the analysis program
itself is getting.
Of course you cannot change anything on the instrument
through the controls during a measurement. For example, you
cannot change the B field from the "Main" control while one
of the analyses is running. But why would you want to
anyway?
All the sub-programs are discussed elsewhere in this
manual:

Stop
This button finally is to completely stop the LabView 3f
control. It will work only after all windows from
sub-programs are closed. When it is pressed while there are
still other open windows, it will change to red as shown
above. Close all windows and subroutines that are still open
to stop LabView.
