The test displays information for the current stage, for
example, the flow path being tested and the setpoint and
actual pressure or flow readings.
To stop the test, press [Clear] during a purge step
(monitor the HS display). Otherwise, the test continues
until it passes or fails.
See "If the test passes"
After the test passes, restore the instrument to operating

condition.
If the test passes all stages, the sampling system is leak free.
If still experiencing leak- like symptoms:
• Check the transfer line.
• Check the interface to the GC.
• If not already done, check the GC. The HS leak test
cannot test for leaks in the GC.
If the test fails, the display provides:
• The reading for the stage that failed (for example, leak
rate or flow rate).
• Command lines to toggle related valves (for example, a
switching valve or the six port valve).
SV1 or SV2 or PV1 or PV2: Scroll to this line and press
[On/Yes] to turn on (energize) the valve, or [Off/No] to
turn it off.
Six-port valve: Scroll to this line and press [On/Yes] to
switch the valve to the load position, or [Off/No] to switch
it to the inject position.
• A selection to exit the test.
Exit test?: Select this line then press [On/Yes] to abort the
test.
• A failure code
See the sections below for troubleshooting information for
each stage of the test.
