Resetting a simulated or running regimen
causes the current activity to stop at the next
cycle of the current regimen step, and
disassociate the regimen from the FlexLink
®
controller. To reset, click on
Reset
in the main
display window. Click on
Yes
when the
program asks for confirmation. The system
will now be in state similar to that which exists
when the Flex Jr.

Tension FlexLink

The Flex Jr.
™
software has the capability of
storing data (a set of waveform points) from a
regimen run to a file on the hard drive. The
filename consists of a “E” or “P” code letter
(
E
for elongation, or P for pressure), the
FlexLink
®
number, a “V” (for vacuum), the
assigned baseplate platform, the user, the
regimen name and a sequence number. If a
tension regimen is run three times on
FlexLink#1, then there will be three data files
on the hard drive with numbers ‘000’, ‘001’
and
‘002’,
respectively
(i.e.,
E_1_V_BaseplatePlatform_User_Regimen
Name_000.dat,
E_1_V_BaseplatePlatform_User_Regimen
Name_001.dat, etc.). The file size depends
on the regimen duration. The current settings
take pressure data every 2 milliseconds (i.e.,
500 points/sec or 1,800,000 points/hour).
Therefore, a one hour regimen will have
approximately a 4.0 Mb data file. To turn
this feature OFF, please contact Flexcell
®
.
To see the stored data, in the
Data Analysis
menu, select
Data Viewer
. Open
the
appropriate .dat file from the C:\FlexSyst
directory. A new window will appear (Fig.
12). The data presented defaults to the raw
data. Moving average can be selected to
display the raw data with data averaged
every 10 seconds.
The
y-Axis control
box
allows for automatic
or manual control of the scale on the y-axis.
If
Auto
is selected, the y-axis scale can be
changed by clicking on one of the two small
double-arrow buttons at either end of the
axis. The button with arrows pointing away
from each other increases the axis scale,
while the button with arrows pointing
toward each other decreases the scale. The
minimum value is -2 kPa and the maximum
is -100 kPa. If
Manual
is selected, the user
can enter the upper and lower limits of the y-
axis scale in the white boxes to the left side
of the axis. The small double-arrows will not
function if
Manual
is selected.
