Control panel pushbuttons (keys)

Selection control key for selection of specific parameter.
The subsequent parameter is selected by every further keystroke.
By pushing the arrow keys the value of a previously selected parameter is increased or decreased. By
keeping an arrow key depressed the value is increased or decreased with increasing speed.
Start the centrifugation run. The rotation display

Acquisition of input and changes.
Stop the centrifugation run.
STOP
The rotor runs down with pre-selected brake step. The LED in the key lights up until the rotor stops.
Pushing the key twice triggers the EMERGENCY STOP.
Selecting the RCF display.

Adjustment possibilities

t/min Running time. Adjustable from 1 - 99 min. in 1-min. intervals.
t/sec Running time. Adjustable from 1 - 59 sec. in 1-sec. intervals.
Continuous run "∞". Set parameter t/min and t/sec to zero.
RPM Revolutions per minute. A numerical value from 500 RPM up to the maximum speed of the rotor can be set.
Maximum speed of the rotor, see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and
accessories". Adjustable from 500 RPM to 10000 RPM in steps of 10 and from 10000 RPM up to the
maximum speed in steps of 100.
RAD/mm Centrifugation radius. Input in mm. For centrifugation radius see Chapter "Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories". The input of the radius is only possible if the RCF display is selected
(LED in the key
RCF Relative centrifugal force. A numerical value can be set, which gives a speed between 500 RPM and the
maximum speed of the rotor. Adjustable up to 100 in intervals of 1, and from 100 in intervals of 10. The
RCF value is automatically rounded up or rounded down with regard to the RPM interval. The input of the
RCF is only possible if the RCF display is selected (LED in the key
Starting steps 1 - 9. Step 9 = shortest starting time, Step 1 = longest starting time.
Brake steps 0 - 9. Step 9 = shortest run-down time, Step 1 = long run-down time,
Step 0 = longest run-down time (brakeless run-down).
PROG Programme Number. 3 programmes can be stored (programme positions 1 - 2 - 3). The programme
position # serves as temporary storage for altered adjustments.
