2-3 How to Use the FUNCTION Area
This centrifuge incorporates a number of features, such as step-mode and other programmed running,
display and setting of centrifugal force, and RTC (real-time control) that can run the centrifuge at a
required date and time. Buttons for these features are displayed and specified in the Run screen
(FUNCTION area).

Description
PROGRAM
You can save run conditions in memory for later use in repeated
operation. This feature also allows step-mode operation (three
normal operations can be combined in a sequence of operations).
RCF
The centrifuge automatically computes and displays RCF values
from set speed, or speed from set RCF values.
g.sec
The centrifuge automatically computes and displays integrator
(g.sec) values from RCF and run time. The centrifuge can also be
operated by entering integrator values.
RTC
Sets a start time or a finish time and runs the centrifuge at a
desired date and time.
The above features can be used in combination.
NOTE To perform a combination of PROGRAM and RTC , first set PROGRAM and then set
the RTC .
Once RTC is activated, you cannot change the run time. You therefore cannot activate
PROGRAM .
