(2) Step-Mode Operation Procedures
Call the number of the program where the step-mode operation is registered and run it according to the
instructions in Section 3-2-5 "Operation Procedures."
Start operation without changing the run parameters after calling the program. (Changing the run
parameters will cancel the called program.)
NOTE
1) The Program display screen in the Run screen displays the following data.
The remaining run time for all steps is the total TIME (run time) for all set steps less the time that the
centrifuge has been running. (In this example, the run has not started yet so the total 3 hour run time is
displayed as the remaining run time.
Since this time does not include the deceleration time between different steps, it does not indicate the
exact remaining time. Use this information as a rough indication of remaining time.
2) When acceleration is performed before the next step, the acceleration time is included in the
remaining time. However, time for deceleration is not counted and the time count resumes
when the following step starts.
3) Run parameters cannot be stored during operation (when the rotor is turning). Perform this
operation when the centrifuge is not running.
4) To combine step-mode operation and RTC (Real Time Control) operation (refer to Section
3-3-4 "RTC (Real Time Control) operation"), set RTC after calling the program.
The centrifuge totals the run time for all programmed operation steps and calculates the RTC
start time.
Programs cannot be called after setting RTC.
5) If a step stores a speed exceeding the maximum allowable speed for your rotor, the incorrect
SPEED setting alert will be triggered. Check the speed settings in all steps and correct as
required.
6) Press [STOP] button if the run has to be stopped. This will stop the rotor and prevent the
centrifuge from proceeding to the next step.
Current step no.
Program No.
