8.2.5 Inlet vent
This function allows an inlet vent after a hard vacuum test stop.
This function is used to return to atmospheric pressure the detector’s inlet, and therefore the connected
part or installation.
This function is secure: confirmation is requested each time the operator requests an inlet vent.
NOTICE
Risk of pollution of the test chamber or of the process
Never program an ‘automatic’ inlet vent when the detector is connected to a hard vacuum test or
process chamber.
►
Select ‘Operator’ and delete the function key allocated to the automatic inlet vent. The inlet vent
must be carried out using the menu, which can be password locked.
