Basic vacuum rules for
the installation
connecting
Use positions The leak detector could be use
in a horizontal position: turn
the control panel for a better
reading.
Position the leak detector so that there is no risk of fall or shock.
We recommend connecting the leak detectors using pipes in
stainless steel with a diameter equal to the inlet port.
The connection between the piece to be tested and the leak
detector must be as short as possible, direct, perfectly tight
(which means it is important to design adapted tools to connect
the piece).
The volume between the tested part and the test chamber (free
volume) must be as small as possible.
The length of the connection influence the "response time". It
means that if the connection is very long (more than1.5 meter
with diameter equal to the inlet of the detector) the signal will
move more slowly.
Don't use plastic flexibles as compressed air tubes.
Check carefully that the material doesn't allow helium
permeation.
