Operation
Run Procedure
Setting RCF
1
Press the
RCF
key.
• The last digit on the
SPEED
display (
0
) flashes, indicating that you can enter the RCF.
2
Press the ▲ or ▼ cursor key until the required RCF is displayed.
• The corresponding RPM is automatically calculated and the centrifuge runs at the
calculated speed.
Setting Run Time
Run time can be set for either a timed run or continuous operation.
Timed Run
Time can be set for up to 9 hours and 59 minutes (if the minutes parameter entered exceeds 59, it is
automatically converted into hours). During centrifugation, the
TIME
display begins counting down
when the rotor starts to spin and continues the count-down until deceleration begins. The
TIME
display shows the time remaining in the run, in hours and minutes. When the time display reaches
zero, the run ends.
Continuous Run
If a run time of less than 1 minute or more than 9 hours and 59 minutes is selected, continuous
operation is activated. Time is not counted down during continuous operation; instead, the infinity
(

) symbol, indicating continuous operation, lights up and time elapsed since the run start is
displayed. The run continues until the
STOP
key is pressed.

Temperatures may vary slightly between instruments. If sample temperature is crucial, test
temperature settings on your instrument using water samples.
