The PhoeniXL
300 dry
allows the vacuum ranges as follows:
6.6.1.4 Partial flow setup
Main menu > Settings > Vacuum settings > Partial flow setup
Through this menu item the settings for a use of a partial flow system can
be set. In the partial flow mode the test sample is additionally evacuated
by an auxiliary pump, which offers the advantageof measuring from 1000
mbar on.
This setting is not possible for the PhoeniXL
300 dry
version.
The PhoeniXL
300 Modul
allows additionally the settings for the forepump (oil
sealed or dry) and selectable pumping speed for the forepump.

.
Softkey No. 2: GROSS only
In this mode the PhoeniXL
300 dry
remains at the inlet flange after falling
below 15 mbar. When the pressure is increasing over 15 mbar the
PhoeniXL
300 dry
switches automatically into evacuation mode. The smal-
lest detactable leak rate is 1 ·10
-8
mbarl/s.
Softkey No. 3: FINE only
In this mode the PhoeniXL
300 dry
remains after falling below 0,1 mbar at
the inlet flange . Valve V1 will be closed. When the pressure at the inlet
flange is increasing > 0.1 mbar the PhoeniXL
300 dry
switches immediately
into evacuation mode. The advantage of FINE only is that while this mode
is running no valve will switch and the leak detector has a high pumping
speed.
