Control knob

For setting the individual parameters.
Turning anticlockwise reduces the value. Turning clockwise increases the value.

Keys and setting options

•
Running time, parameters t/hms.
TIME
h: hours. Adjustable from 1 h to 99 h, in 1 hour increments.
m: minutes. Adjustable from 1 min to 59 min, in 1 minute increments.
s: seconds. Adjustable from 1 s to 59 s, in 1 second increments.
•
Continual running "∞"
•
Revolution, parameters rpm.
RPM
Adjustable from 50 rpm to a maximum rotor speed of the rotor (Nmax), in increments of 10. For maximum
rotor speed, see chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories".
•
Relative centrifugal force, parameter RCF.
RCF
The RCF is shown in brackets 〉 〈. The LED in the button lights up.
The figure that is adjustable is the figure that produces a revolution speed between 50 rpm and the
maximum rotor speed (Nmax). Adjustable in increments of 1.
•
Centrifuging radius, parameters RAD.
Adjustable from 85 mm to 330 mm in 1 millimeter increments. For centrifuging radius, see chapter
"Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories".
Run-in and run-out parameters
•
Run-in steps, parameters
Step 9 = shortest run-in time, ... Step 1 = longest run-in time.
•
Braking step, parameters
Step 9 = shortest run-out time, ... Step 1 = long run-out time, step 0 = non-braked run-out.
•
Brake switch-off revolution, parameters N Brake.
Adjustable from 50 rpm to the maximal rotor speed (Nmax) in increments of 10.
Once the rotor speed has been reached, non-braked run-out begins.
•
Temperature (only for centrifuge with refrigeration)
T/°C
Adjustable in degrees Celsius (°C) or in degrees Fahrenheit (°F). For setting the temperature unit, see
chapter "Temperatur-Einheit einstellen/Setting the temperature unit".
Parameters T/°C = degrees Celsius (°C).
Adjustable from -20°C to +40°C, in 1°C increments (for the heat/cool option, adjustable in the range from -
20°C to +90°C).
Parameters T/°F = degrees Fahrenheit (°F).
Adjustable from 4°F to +104°F, in 1°F increments (for the heat/cool option, adjustable in the range from -
4°F to +194°F).
The lowest temperature that can be reached depends on the rotor (see chapter "Anhang/Appendix,
Rotoren und Zubehör/Rotors and accessories").
•
Call up programs and program linkages; parameter RCL.
PROG
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.
•
Link programs; parameter EDIT.
•
Start "Machine Menu" (keep the key held down for 8 seconds) and select the parameters from this menu.
