7.2.1.6 USER ID
The user ID entry screen is presented. The last user ID can be accepted, a new
user ID may be entered, or a previously entered user ID may be selected from
the user ID drop down list. If this step is turned OFF in
[Tools] , [Options] ,
[Initialize Test] (see Section 11.5), the screen is not shown and the last user ID
selected is automatically used.
Any time a new user ID is entered, it is automatically added to the user ID list.
Names can be removed from the list using
[Tools] , [Options] , [Maintain Lists]
(see Section 11.4).
7.2.2 RUN TEST
After test initialization is complete (see Section 7.2.1), run test begins.
The test procedure is defined by the Test Definition (see Section 9) associated with the
selected DUT Definition (see Section 8). Prior to running a test, various aspects of run
test behavior may be customized (see Section 11.6).
During run test the main menu bar is disabled but the <Run Toolbar> is active. Use the
<Run Toolbar> keys to view detailed DUT or Test Definition information while the test is
running, to step test points back or forward or to display test run windows (see Section 6.5).
A test that is running can be aborted at any time by pressing the <Abort Test> button on the
<Run Toolbar> . Before aborting the test, COMPASS requires confirmation and queries whether
the partial Data File containing the data collected for the test so far should be saved. The Data File
can be automatically deleted by setting Data File Options are set (see Section 11.8).
The run test sequence is as follows:
Run purge : If purge is specified in the Test Definition (see Section 9.5.8), COMPASS will
set the purge flow rate, activate the necessary molbox valves to purge the molbox and
then start the purge count down. When the purge time expires the valves are automatically
adjusted back to normal operation.
Run leak test: If a leak test is specified in the Test Definition (see Section 9.5.7) and the
reference molbox supports leak tests, a message displays to notify the user to make the
necessary preparations for a leak test. After the message is confirmed, the leak time
count down begins. All leak tests last approximately 60s. When the leak time expires,
the status bar displays the Pass or Fail status. The results of the leak tests are also
recorded in the Data File. Unless the
<Abort on failure> option is checked on the [Leak Test]
tab of the Test Definition, test execution continues regardless of the leak test results.
Change molbloc: If a molbloc change is specified for the test point in the Test Definition
(see Section 9.5.2), COMPASS displays a prompt to change the molbloc. When the
message is confirmed, the new molbloc information is loaded into memory. If the molbloc
has not changed or an error occurs in loading the new molbloc, an error message displays.
The molbloc range and serial number are logged in the
<molbloc> column of the data grid.
If purge after molbloc change is specified, the purge function described in Step is repeated.
If leak test after molbloc change is specified in the Test Definition, the leak test described
in Step is repeated. The result of each leak test is logged in the
<Status> column of
the data grid as well as in the Data File (see Section 18.4).
