3-3-2 RCF Display and Setting Function

3-3-2 RCF (Relative Centrifugal Force) Display and Setting Function

This centrifuge stores the maximum and average radii of each rotor in internal memory. Setting a
speed causes the centrifuge to automatically calculate and display the RCFmax value (the
maximum centrifugal force of each rotor) and the RCFavg value (the average centrifugal force of
each rotor). Likewise, when an RCFmax value or RCFavg value is set, the centrifuge will
automatically calculate and display the speed. The following is a description of how to display and
set RCF.
(1) When the centrifuge calculates the RCF value from the set speed or calculates the
NOTE
set RCF value from the speed, the numeric values may not be the same and deviate
slightly.
(2) Some of the rotors available for this centrifuge have outside and inside tube cavities.
(Refer to the instruction manual supplied with the rotor and also the information on
rotors supported (part No. S998453) by the CP-NX series.) When rotors with both
inside and outside tube cavities are used, the instrument can calculate the speed
and RCF value of the outer tube cavities.
Step Touchscreen operation
1 Press the rotor indicator field in
the Run screen.
If the desired rotor has not
been set, press the rotor
indicator field to select the
desired rotor.
For information on how to
select a rotor, refer to Section
3-2-3 "Rotor Selection."
2 Press the [RCF] button in the
Function Selection Area in the
Run screen.
Screen displays and notes
