The Primary Function keys are the keys below the SET DISPLAY.

RECALL
Each key is positioned below a corresponding field in the SET DISPLAY, allowing simple, direct access
to basic run parameter controls:
ROTOR
• Press the ROTOR key to specify a different rotor than the one shown in the SET DISPLAY. This
is necessary if the rotor or bucket/ carrier system installed in the centrifuge are changed.
• The rotors are listed by the rotor name. Press the ROTOR key repeatabely to scroll through the
rotor list for selection.
• The correct identification of the installed rotor is necessary for the set SPEED limits, correctly
calculate RCF, and accurately control sample temperature.
• If a rotor is able to use buckets/carriers with different maximum radii, each configuration will be
listed for selection, to calculate the different RCF.
• The ROTOR key is not active when a run is in progress.
Note To ensure that the installed rotor will always be correctly identified, make it a practice to
change the SET rotor name immediately after changing the installed rotor.
SPEED
• Press the SPEED key to specify a different rotor speed in revolutions per minute (rpm) or relative
centrifugal force (RCF, also known as g-force).
• Speed is selectable from 300 to 4700 rpm, up to the maximum rated speed for the specified rotor,
or as an equivalent RCF calculated at the maximum radius of the specified rotor (rotor geometry
only, with no accounting for adapters).
• Press the SPEED key repeatedly to toggle between rpm and RCF or RCF. Pressing once causes the
value to flash so a change can be made in that mode. Pressing again changes to the other mode and
displays a value equivalent to the previouse. Pressing again causes that value to flash so a change can
be made, pressing again changes the mode back, and so on.
• An entered value will continue to flash (prompting input) when it is out of range for the SET
rotor. The formula used to calculate RCF is:
