A Pass or Fail message will display at the end of the leak check cycle.
The leak check pass criterion is a pressure drop of 25 mmHg or less.
The Sampler will display a message at the end of the cycle indicating
the vacuum loss (mmHg) during the 60 second leak check, and a pass
or fail message. Open the manual valve on the Sampler then release the
vacuum (slowly) by opening the flow audit adapter valve. (For more
information on the leak check, see “
External Leak Check
” on page

.)

If a leak check fail message is displayed on the screen, check the tube
connections in the Sampler (including the flow audit adapter), ensure
that the filter cassette is properly installed and a proper seal is in place
and repeat the leak check procedure.
7.
If leak check fails a second time, the leak is external to the filter. Isolate
the leak and repair.

After a successful leak check, slowly open the valve on the flow audit
adapter.
