Purpose
The helium pollution prevention function prevents the detector from
being polluted by helium when the part or installation to be tested
contains a lot of helium.
Leak detector in test mode, if the signal increases quickly above
depollution reject point, the cycle is automatically ended and the leak
detector stays in stand-by mode until the helium has decreased.
Note: There is no message to inform the operator that the detector is
over again ready for a new test.
Note:

= Wait and pump a few hours (the best
solution is one night)
= Purge with N2 flow or air flow
Note: When the detector reaches the 10

mbar threshold, it
automatically pass in gross leak test mode.
