3.3.3 Preselection of brake intensity and acceleration
This function is activated through the key "Accel/Decel" (6) (refer to figure 15).
By pressing the key once the word "accel" (M7) flashes in the display "Acc/Dec" (A-2). The desired acceleration
can be pre-selected by the adjusting dial (4). The value 0 is equivalent to the lowest and the value 9 to the highest
acceleration.
By pressing the key "Accel/Decel" (6) twice, the display "Acc/Dec" (A-2) indicates the word "decel"(M8). Now
the desired brake intensity can be pre-selected by the adjusting dial (4). The value 9 is equivalent to the shortest and
the value 0 to longest possible brake time.
See "table 5: acceleration and deceleration times" (APPENDIX). There the acceleration and deceleration times
for the acceleration and deceleration stages 0 to 9 for permissible rotors are shown.

3.3.4 Pre-selection of temperature (Only FC5513R)
This function is activated by the key "Temp/Setup" (13). After pressing this key in the display "Time/Prog" the
indication "°C" (A-4) flashes. By the adjusting dial (4) the desired test temperature can be pre-selected in steps of
1°C in a range from -20°C up to +40°C.
The value is indicated permanently in the display (figure 16) - before, during and after the run.
Please notice the respective lowest temperatures of the rotors at maximum speed!

3.3.5 Pre-cooling (Only FC5513R)
If the samples are temperature-sensitive it is useful to pre-cool the centrifuge, the rotor and eventually the buckets to
the required working temperature. Therefore, insert the desired rotor and pre-set the respective temperature. By
simultaneous pressing the keys "Temp/Setup" (13) (refer to figure 17) and "Time" (6) you start the run. While
running, the unit chooses automatically a rotational speed that is equivalent to 20 % of the permitted rotational speed
of the respective rotor. After the pre-set temperature is reached you can leave the pre-cooling run with the "Stop" key
(9). Depending on the inserted rotor the pre-cooling goes between approx. 10 and 20 min.
