assume that the HS is already prepared and that the GC is
leak- free.
The built- in cross port leak test sequentially checks for leaks
across the six port valve, from the carrier side to the vial
pressurization side.
The test consists of two parts. If one part fails, the test
reports the failure and stops before attempting any
subsequent parts. Correct the problem, then re- run the test.
Continue correcting problems and retesting until the test
completes successfully.
