Per discussions, one of the alarm conditions would be to see if the
magnet currents are fluctuating (at least at the 10^-8 level).
If not, and if the data are not "Invalid", I make the alarm, the logic
being that a frozen value is a bad sign.
Generally they do fluctuate but in any 2 minute interval there's a
good chance the value remains constant with 9 (!!) digits of accuracy.
Must be some discretation of the data. So I give up on that and will
only watch for a drift.
I probably don't understand the control system enough to make
an alarm. Have fun watching your charts ...
