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 500 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 acceleration, parameters RCF.
RCF
The figure that is adjustable is the figure that produces a revolution speed between 500 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 100 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.
Parameters T/°F = degrees Fahrenheit (°F).
Adjustable from 4°F to +104°F, in 1°F increments.
The lowest temperature that can be reached depends on the rotor (see chapter "Anhang/Appendix,
Rotoren und Zubehör/Rotors and accessories").
•
Start programs, parameters RCL.
PROG
•
Save programs, parameters 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.
•
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.
•
Start centrifugation run. The LED in the key is lit during the centrifugation run, as long as the rotor is
START
revolving.
•
Short-time centrifugation.
The centrifugation run occurs while the key is kept pressed. The LED in the key is lit during the
centrifugation run, as long as the rotor is revolving.
•
Saving entries and changes.
•
End centrifugation run.
STOP
OPEN
The rotor decelerates with the preset run-down parameters. The right-hand LED in the button lights up
until the rotor is stationary. Once the rotor is stationary the left-hand LED flashes in the button. Pressing
the button twice triggers the EMERGENCY STOP.
•
Unlock the lid.
The left-hand LED in the button goes out.
•
Leave parameter input and the "Machine Menu".
