Programs: Program locations 1 to 99 and PREC. program linkages: Program locations A to Z.
•
Save programs and program linkages; parameter STO.
99 programs can be saved (for centrifuges without refrigeration: program places 1 to 99, for centrifuges
with refrigeration: program places 1 98 and PREC). The program place PREC (PRECOOLING) is
reserved for the precooling program. Program place 0 is used for temporary storage for centrifuge data
from the last centrifugation run. No programs can be saved at this program place.
It is possible to save 25 program linkages (program locations A to Z; there is no program location J). A
program linkage can consist of 20 programs.

Start "Machine Menu" (keep the key held down for 8 seconds) and select the parameters from this menu.
•
Start rotor precooling (only for centrifuges with refrigeration). The LED in the key is lit during the
centrifugation run, as long as the rotor is revolving.
Precooling of the rotor takes place automatically with the PREC (PRECOOLING) program.

Enter centrifugation parameters

If no key is pressed for 8 seconds long after the selection or during the input of parameters, the previous
values will be shown in the display. The input of parameter then has to be executed again.
When you enter several parameters, the
settings for the last parameter.
If parameters are changed, the program place number is displayed in parentheses (). This means that the
centrifugation data in the display no longer corresponds to the centrifugation data from the program place that
has been saved.
You can no discontinue entering parameters at any time by pressing the key
adjustments are not saved.
