deactivated at this time. DUT’s that are setup to use a density correction or DUTs with actual flow units
must use pressure and temperature data acquisition.
The Run DUT option is similar to running a test without a fixed sequence. All operations available in
the test are available on the <Control Toolbar>. Use the toolbar to change molbox settings, purge,
leak check and tare as desired. Use the data acquisition <Control Toolbar> options to create a test
data file and log test data (see Section 6.6.10).
Based on the DUT Definition, not all
<Control Toolbar>
functions will be available. For example, if manual
flow control is selected, the
<Flow Control>
option will not be available. Use the available features of the
<Control Toolbar>
to purge, leak test, or tare the molbox, change the flow rate and stability criterion and
to log data to a data file.
COMPASS
polls the System Configuration instruments and responds to the
toolbar options until the
[Abort]
button is pressed.
Using any of the <Control Toolbar> automatic data logging options can result in very large data files.
These are files with significantly greater than 1000 data points. COMPASS was not intended to
manipulate such files. Lower performance PC’s will experience significant delays in generating reports
and plots of such data files. Therefore, it is not recommended to use the plotting and reporting
functions with very large data files. Instead, export the data file to a spread sheet application for
further analysis.
