Set up COMPASS for my volume or actual flow units?
From the [Setup], [DUT], [Range] tab, select the <Unit> drop down under the “Flow
Range” section of the window. Scroll through this list to find the units you desire. If they
do not exist they can be added using the
<Edit Units> selection or the [Tools], [Options],
[Flow Unit Editor] option (see Section 8.5.4). When selecting volume flow units,
COMPASS requires the actual operating conditions (temperature and absolute pressure)
at the DUT. The temperature and pressure can be either acquired automatically or
entered manually by the user. The
[Setup], [System] selections determine the data
acquisition method for pressure and temperature (see Section 10.2). The [Tools],
[Options], [Run Test] tab controls manual entry (see Section 11.6).
Test one specific DUT without having to enter its serial number and ID during
test initialization?
Set the DUT up as an individual DUT (see Section 8.5.2). Individual DUTs define unique
DUTs and include the DUT’s serial and ID number. When a DUT definition is run, it is
assumed there is only one DUT with the specified serial number and ID.
Repeat a point in a test?
Use the [Skip Back] and [Skip Forward] keys from the Run Test Toolbar (see Section 6.5.1).
Check what DUT or Test Definition is being run and check DUT and Test Definition
details
while a test is running ?
Click on the [View DUT] or [View Test] Run Test Toolbar keys to cause the DUT or Test
Definition screen for the current DUT or test to appear without affecting test execution.
Close or move the display to view the previous run screens (see Section 6.5.1).
Repeat the same test several times without having to pause or restart the test?
Specify multiple test cycles in the Test Definition. In the [Sequence] tab of the Test Definition
(see Section 9.5.4) specify a number >1 under <Number of Test Cycles> . The complete flow
point sequence will run for the number of times specified without initializing between runs.
If all test operation aspects are automated, and
[Tools] , [Options] , [End Test] , <Prompt
to repeat last test point> is NOT checked, the cycles will run without interruption
(see Section 11.7).
Create a custom plot of data logged in the data file?
There are two ways of going about this. First, COMPASS provides the ability to create
custom plots within the [Plot Properties] toolbar option (see Section 12.4.2). A label for the
plot as well as the X and Y data can be set up. The second method requires the use of a
third party spreadsheet application, MS Excel for example. Import the delimited
COMPASS
data file and use plot functions within the tool to create a plot.
Avoid having to go through undesired initialization steps each time a test is started?
Use the [Tools] , [Options] , [Initialize Test] tab to set preferences to include or exclude
the various test initialization steps (see Section 11.7).
Abort a test that is running?
Press the [Abort] key on the Run Test Toolbar (see Section 6.5.1) or use the [Run] ,
[Abort Run Mode] menu option while the test is running.
Change the default RS-232 port for reading DUTs so that I don’t have to re-select the
port manually every time in the <Setup DUT> screen of test initialization?
Use [Setup] , [System] , <Default DUT RS232 Port> to edit the default DUT RS-232 port
(see Section 10.2).
