Operation
Create DAA profile
A new DAA profile can be defined during the ongoing
process on basis of the current operating parameters or in
advance using specified parameters.
Switch to screen 2 of the operating mode. Touch the
[New] button to create a new profile.
The view switches to screen 3. Here, you can define the
following parameters (tap on the value to switch between
the options or to open the keyboard):
•
[Mixture distillation]: Selection between mixture
distillation and simple distillation
•
[Intensity]: relative temperature rise (1 – 10 °C)
•
[End pressure]: only when selecting [Mixture
distillation], required end pressure (1 – 1,000 mbar)
•
[Hysteresis Δp]: Hysteresis for the opening pressure
of the vacuum valve, see section „Hysteresis opening
pressure of the vacuum valve" on page 102
•
[Rotation]: Rotation speed (10 – 280 rpm)
•
[Heating bath]: Heating bath temperature
(20 – 210 °C)
•
[Recirculation chiller]: Recirculation chiller
temperature (-10 – 20 °C)
After having entered all values and pressed [Save], open
the keyboard and assign a unique name to the profile.
The new profile can be loaded directly by pressing [Load].
The view switches back to the start window with the
operating parameters of the profile.
Graphics (curves)
On screen 4 of the operating mode, the process-specific
graphics (curves) for vacuum pressure, rotation speed and
condenser temperature are displayed in real time.
The boiling points are marked In the temperature curve.
All diagrams are touch-sensitive: tap on a diagram to
zoom the display in and out.
