3.3.4 Pre-selection of temperature (Only Refrigerated Models)

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 Refrigerated Models)

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 permit ted 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.

3.4 Radius correction

If you use adapters or reducers it could change the centrifugal radius of the respective rotor. In that case you can
correct the radius manually. Please proceed as follows:
Close the lid, then press the key "Time" (6) (refer to figure 21) and the key "Prog/Setup" (11) at the same time
and hold them.
In the display "Time/Prog" (A-3) the word "radius" (M9) appears. By the adjusting knob (1) you can preselect the
respective radius correction (See Table 7, APPENDIX) in steps of 0.1 cm. As soon as you have set a radius
correction the word "radius" (M9) appears. This word will be visible until you put the radius correction back to 0
again.
