3.3.4 Pre-selection of temperature (Only FC5515R)
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 knob (1) 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 19) - before, during and after the run.
Please notice the respective lowest temperatures of the rotors at maximum speed!

3.3.5 Pre-cooling (Only FC5515R)
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 20) 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 (10).
Depending on the inserted rotor the pre-cooling goes between approx. 10 and 20 min.
