Button "Standard unit test"
Apart from the process phases of the freeze-drying process ("Freezing",
"Warm-up", "Main drying" and "Final drying") and the operating mode
"Defrosting", the button "Standard unit test" is also available. This button

functionality and processes of the freeze-dryer.

This test is used to determine the following performance parameters of a
freeze-dryer:
• vacuum decrease rate

• minimum ice condenser temperature
Prior to performing a test, ensure that the chamber is dry and unloaded
and that the ice condenser is defrosted!
Procedure:
• In the main window "Process", select the button "Standard unit test"
under "Operating mode: select/start".
• Select "Performance test" and start the test via the "Run" button.
The test will be performed. The parameters will be measured at defined
points of time, evaluated, and displayed in a dialog box (see the following
