BÜCHI Vacuum Controller V-800/V-805
8.9.2 Possible interventions into the regulating
process
Increase the system pressure or interrupt pressure drop in
the start phase ð[Pé]. The apparatus goes into the hold
mode and regulates further to the actual value. If necessary,
the apparatus is partially ventilated. [ESC] puts back into
the manual RUN mode with the original set point.
[OK] puts back into the manual RUN mode with the new
set point. Use [AUTO] to put distillation back into the
automatic mode.
Change into the manual mode ð[MAN]. Now, distillation
can be continued manually.
8.10 Repeating the last distillation performed
The last manual distillation performed is automatically saved
in active working memory.
8.10.1 Performing the distillation
Choose repeat mode [MENU] ð[MODE] ð[REPEAT]
ð[OK].
The display automatically goes into the basic state of the
repeat function.
Now, the controller is ready and you can use [RUN] to start
it.
[SHOW] displays the pressure course graphically.
[STOP] ends the distillation and ventilates the apparatus
(unless configured otherwise).
The program can be saved from the basic state for applications
later: [MENU] ð [MEMORY] ð [STORE] ð [OK] (program
is saved as gradient).
