Program mode
A program contains all of the data that are required for a centrifuge run.
Certain sedimentation results can be repeated under identical conditions.
Programs can be loaded, executed, edited, and deleted when the
centrifuge is at a standstill.
A maximum of 60 programs can be stored under the numbers 1-60. The
program "RAPID_TEMP" does not occupy any storage location and cannot
be deleted. It is used to bring the centrifuge to a specific temperature
without any vessels.
"--" means that the values that are currently set are not a stored program.
The programs can be protected against unauthorised use, modification, or
deletion with the aid of a code (see chapter 6.3.2.7 - "Parameters menu").
Stored programs are listed in the "Process library" menu
.
