To run an assigned regimen, click on
Start
in
the main display window (Fig. 8) after the
regimen has finished downloading. Be sure
that the vacuum pump is ON and all other
connections are made. The membranes should
begin flexing, and the assigned regimen will
be in progress.
The progress of the regimen for the currently
selected FlexLink
®
will be monitored
continuously. The displays for Run Time,
Step #, Cycle #, Jump #, and Min and Max %
will update, as will the
actual waveform data
returned by the FlexLink
®
. Additionally, a
progress bar below the graph will display the
percentage of the regimen that has been
completed.

IMULATING

EGIMENS
The
Simulate
button is used to simulate a
regimen graphically without actually running
it. Simulating a regimen will give the user an
idea of the waveform output before actually
running the regimen. To start a simulation,
click on
Simulate
in the main display
window. A waveform will begin moving
across the graphic display. This waveform
corresponds to the ideal waveform as
generated by the Flex Jr.
™
software, and is the
actual waveform pattern sent to the FlexLink
®
during the download process. For certain
waveforms (e.g. square waves), the idealized
pattern may appear to have some unusual
elements (e.g. rounded corners). The
purpose of these unusual elements is to
accommodate for the lag time during sudden
changes in pressure (e.g. rising/falling edge
of a square wave). Without these unusual
elements, the valve controllers may oscillate
for a period of time (e.g. dampened sine
wave during beginning of plateau in a square
waveform).

To pause a simulated or running regimen,
click on
Pause
in the main display window.
Click on
Yes
when the program asks for
confirmation. Pausing will cause the current
simulation or actual running of the regimen
to stop at the next cycle of the current
regimen step. Pausing is different from
stopping, in that pausing leaves the regimen
at its current position, whereas stopping
causes the regimen position to be set to the
beginning of the first regimen step.

To resume a paused regimen, click on
