Setting Run Temperature; Setting Acceleration And Deceleration Rates; Acceleration Settings - Beckman Coulter Avanti J-26XP Instructions For Use Manual

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).
The system controls the chamber temperature to within 2°C of the set temperature.
NOTE
temperature within 1°C of set, perform the temperature calibration procedure provided in the
Appendix.

Table 3.2 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.
