2-3-1 Programmed Operation
When a centrifugal condition is to be used frequently, entering the same condition every time you want
to perform centrifugation is inconvenient.
This centrifuge has a programmed operation feature that stores run conditions. Storing run conditions
which you often use allows you to call those conditions however often you may wish, thus saving time
in setting. (Even while the POWER switch is OFF, this centrifuge retains the conditions entered.)
The memory in the centrifuge can contain 30 sets (No.1-No.30) of run parameters and 3 sets
(No.31-No.33, No.41-No.43, No.51-No.53) of run parameters for three-step (step-mode) operations.
After recording run parameters (speed, run time, temperature, etc.) for three-step operation, you can
recall and perform those steps successively with the saved run conditions (i.e., step-mode operation).
