For quick access from the main screen, configure a function key to [VENT] (see chapter
“Function keys”).
●
The [VENT] function key is required for the operator to carry out a manual inlet vent
(see chapter “Function keys”).
●
To lock the command for the inlet vent valve, delete the [VENT] function key. The icon
remains on the main screen as an indicator but manual activation by the operator is
disabled.
By connecting an inlet vent (or nitrogen) line to the inlet vent, the detector’s tracer gas pol-
lution is reduced.
8.2.6 Memo Function
This function freezes the main screen at the end of a test: the last measured leak rate from the test is
displayed and flashes.
This function is only available with the ‘hard vacuum’ test method as soon as the ‘gross leak’ test mode
is reached.
