Setting Run Temperature

Select a run temperature between –10 and +40°C, in 1°C increments.
NOTE
For runs at temperatures other than ambient, always refrigerate or warm the rotor to the required run
temperature before the run. For low-temperature runs, precool the system by running a precooled rotor
at 2000 RPM at the required temperature for at least 30 minutes.

• After you release the knob, the display shows the selected temperature.
• After 5 seconds, the display reverts to the actual current chamber temperature.
• When the run begins, the display shows the rotor temperature 2°C (after a period of
temperature equilibration).
NOTE
The system controls the chamber temperature to within 2°C of the set temperature.

Table 2.2 describe the acceleration and deceleration settings.
Reduced torque is used from 0 to 500 RPM, lasting approximately
2 minutes. (The time varies depending on the mass of the rotor in use.
Larger rotors take longer.). Above 500 RPM, full torque is used until set
speed is reached.
