2-3-3 Displaying and Setting RCF
This centrifuge stores the maximum and average radii of each rotor in the internal memory. Setting a
speed causes this centrifuge to automatically calculate and display the RCF (relative centrifugal force)
value, while setting an RCF value causes the centrifuge to automatically calculate and display the
speed.
This section describes how to display and set a RCF value.
NOTE The RCF value computed from a certain speed and the speed computed from a certain RCF value
may not be identical due to a residual in the numerical value.
NOTE
Some applicable rotors to this centrifuge have outside tube cavities and inside tube cavities in them
(see the rotor instruction manuals and "Applicable rotors to the CR-N series centrifuge"). This
centrifuge can compute the RCF value and the speed in outside tube cavities. Some applicable
rotors to this centrifuge have large tube cavities and small tube cavities in them (see the rotor
instruction manuals and "Applicable rotors to the CR-N series centrifuge"). This centrifuge can
compute the RCF value and the speed in large tube cavities.
(1) How to display and set a RCF value
Step
Touch panel operation
1
Check that the desired rotor is
displayed in the ROTOR
indicator of the Run screen.
When the desired rotor is not
displayed, press the ROTOR
indicator to show the ROTOR
CATALOG screen.
(For selecting the rotor, refer to
section 2-4.)
2
In the FUNCTION area of the
Run screen, press the
button.

○
When there is no rotor name on the ROTOR indicator, even
if you press the RCF button, the above box does not
appear.
○
The specified setting of a RCF value, the specified setting
of a Sample Height, and the current status of a RCF value
are displayed In the above box.
