Neutral gas purge and inlet vent
connection
Purpose
Neutral gas purge
 Used to accelerate the cleanup of the helium background noise in
the pumps after detecting a significant leak.
 Make High Sensitivity tests easier due to the reduction and
stabilization of the helium background noise.
 As a supplement to the neutral gas purge, use the “He max”
function (
C 401).
 Vent the inlet of the detector and the connected part to
atmospheric pressure.
 Could be used to accelerate the cleanup of the helium
background noise in the leak detector after detecting a
significant leak.
Inlet vent
The neutral gas purge and the inlet vent are connected on the same
port: the same gas is used for both (ambient air or neutral gas).

Connection to the leak
detector
Neutral gas purge
 If no purge system is connected, the gas purge is connected
to the ambient air and maintains an air flow inside the leak
detector.
 The neutral gas purge status (open or closed) depends on the
software. No parameter can be changed by the operator.
 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 ambient air.
