FEATURE DESCRIPTION
System leak
test
(check box)
Check this box to include a leak test at the beginning of the test. If a leak test is
run, results are included in the test’s Data File. Use the
<Abort test on failure>
to cause the test to abort after a leak test failure. Do not check this box if you
want the test to continue after a failed leak test.
Leak test after
molbloc
change
(check box )
Check this box for a leak test to be run after any molbloc change included in the test
point sequence. If the test fails, the failure is identified in the
<Data Grid><Status>
and in the test’s Data File (see Section 18.4). Use the <Abort test on failure>
to determine whether the test should continue after a leak test failure.
Abort test on
failure
(check box)
Check this box to cause the test to abort if a leak test is failed. If not checked,
the leak check failure is recorded in the test’s Data File but the test continues. Note
that leaks in the flow system may cause the test data to be invalid.
9.5.8 [PURGE] TAB
The Test Definition [Purge] tab is used to specify whether a gas purge routine will be run at the
beginning of the test (see Section 7.1) and/or after molbloc changes. The purge routine used is
the molbox purge function
(see the molbox Operation and Maintenance Manual, Purge Section).
The purpose of the [Purge] tab’s fields and settings as well as instructions on how to use
them are provided in Table 31.
