3-3-1-3 Step-Mode Operation Procedures
3-3-1-3 Step-Mode Operation Procedures
This centrifuge is provided with a "step-mode operation" function that can store two or more run
parameters in one program memory area and a total of 30 steps. This allows it to change speed, run
time, temperature and other conditions during operation.
For example, you could set the speed of a step to 0 rpm to stop rotation to enable opening and closing
vacuum leaks and doors. This makes it possible to register in advance the repeat count of samples
that are removed and processed each run under the same separation conditions, which prevents
processing samples too many or too few times.
Operation procedures are described using examples below.
(1) Registration Procedures for Step-Mode Operation
[Setting example]
The following describes the setup procedures for continuous operation under the three-step run
parameters shown in the figure below.
In this example, the operations described in Fig. 3-3-1 (1) will be performed automatically.
