Section 7: Additional Features
To enable additional users, select the
Add User
button and enter a user name in the text box and
click OK.
The following descriptions detail the parameters that you may wish to alter for each user.
Data File Path
Indicates the complete path (excluding file name) where all VP-ITC data files will be saved. The
specified path should be located on a hard drive and not on any floppy or CD-ROM drives.
Probably most convenient will be to create and use sub directories off of the /data sub directory
which was created by the VPViewer installation program. This setting may only be changed
while the VP-ITC is in the Thermostatting state. To change the current data file path, double
click on the existing path text and a dialog box will open allowing you to change the current path.
Setup File Path
Indicates the complete default path (excluding file name) where all VP-ITC setup files will be
written to. The specified path should be located on a local hard drive and not on any floppy or
CD-ROM or network drives. To change the current setup file path, double click on the existing
path text and a dialog box will open allowing you to change the current path.
Init. Setup File
Specifies the initial setup file that will be loaded into the experimental control window the first
time it is opened. Specifying a *.inj file here will result in an initial ITC. Lastly, specifying the
initial setup file as LastRun1.inj will result in the last run parameters that were executed on the
ITC cell to be loaded at startup.
Cells Boot Temp. (Deg. C)
Determines the initial thermostat temperature upon launching the VPViewer application.
Immediately after starting VPViewer, the system will enter the Thermostatting state, go to the
boot temperature and thermostat there until the user takes action which causes the VP-ITC to
change temperatures (changing current thermostat temperature or beginning an experiment).
Default Shield DT (Deg. C)
The Default Shield DT (1 deg C.) should be used. Do not change this value without first
consulting with a MicroCal engineer.
Analog Input range (Volts)
Click on the arrow for the Analog Input range drop down list.
The default value of +/- 1.25 Volts is the most sensitive range
for input data and should normally be selected. If you expect
an experiment will be strongly endothermic or exothermic you should select a larger input voltage
range to prevent the peaks from being clipped by an out of range signal.
