Use
Neutral gas purge
If no purge system is connected, the neutral gas purge is connected
to the ambiant air and maintened an air flow inside the leak detector.
Even if the leak detector does not use the neutral gas purge, the
male quick connector delivered with the leak detector should always
be connected to the female free flow quick connector.
The inlet vent status (open or closed) depends on the parameters set
by the operator ( C 500).
If no inlet vent system is connected, the inlet vent is connected to the
ambiant air.
Used to accelerate the cleanup of the helium background noise in
the pumps after detecting a significant leak.
Make high sensitivity testing easier due to the decreasing and
stabilization of the helium background noise.
As a supplement to the neutral gas purge, use the “Depollution”
function ( C 560).
Used to accelerate the cleanup of the helium background noise in
the leak detector after detecting a significant leak.
Make high sensitivity testing easier due to the decreasing and
stabilization of the helium background noise.
Allows to regulate the gas flow inside the leak detector, leak
detector in stand-by.
