Translation of the original operating manual
Change scale unit (2)
This dialog box is used to change the unit of measurement for the
temperature and vacuum.

Special equipment: Preselection of the aeration medium (3)
This function can be performed in the manual mode or saved together with
a program (see chapter 6.5.3.1 - "Creating a program").
If the freeze-dryer is equipped with an automatic aeration valve and
automatic valves for media selection, this dialog box can be used to
preselect the medium that is to be used for all of the aeration medium
requests in the manual mode (as of the start of the main drying phase) and
during the "Aeration" section. The phases "Freezing" and "Warm-up" in the
manual mode and the operating modes "Defrosting", "Leakage test", and
"Media drain" always use air for aeration.

If the vacuum control system of the freeze-dryer uses a controlled gas
inflow (gas injection, bleeding), the preselected medium will be used for this
purpose.
