Entering Run Parameters

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.
1
Turn the
TEMP°C
knob until the required temperature appears in the display.
•
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.
*
To control
temperature within

1°C of set, perform the temperature calibration procedure provided in the
Appendix.
Setting Acceleration and Deceleration Rates
Table 3.1 and Table 3.2 describe the acceleration and deceleration settings. Figure 3.1 provides a
graphic representation of these settings.
* During transient conditions, such as acceleration and deceleration, rotor temperature may be outside this range.
Table 3.1 Acceleration Settings
Maximum Acceleration
(not available with the
JS-24.38 and JS-24.15 rotors) Slow Acceleration
Full torque is used from 0 rpm
until set speed is reached 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.
