While Function runs, the
process bar fills up to show
progress. The slider moves
as the bar fills, and the
number above updates
with the current
concentration/diafiltration
value (see example below).
Similar to the Progress Bar, the live value’s position (as
indicated by a thick grey slightly longer line) on the alarm
bars will adjust to show levels. The position of the bar
will show the user how close the live value is to a high
stop (thick red line), high alarm (thin red line), low stop
(thick blue line), and low alarm (thin blue line). When the
alarm is raised, the window on the right is shown.
