Description
This screen displays the set speed (rpm) or RCF (x g) for the given program when the centrifuge is
at rest, depending on which parameter is selected During a run, this screen displays actual speed
or RCF.
This screen displays either the set run time or the centrifugal radius when the centrifuge is at rest,
depending on which parameter is selected.
During a run, this display shows only time remaining (timed runs) or time elapsed (during
deceleration, 'hold' runs and 'pulse' runs).
This screen displays either the acceleration or the deceleration profile selected for the given
program. The value of the acceleration profile is displayed either during acceleration or when the
acceleration set button (8) is pressed. The value of the deceleration profile is displayed either
during deceleration or when the deceleration set button (9) is pressed.
This screen displays either the acceleration or the deceleration profile selected for the given
program. The value of the acceleration profile is displayed either during acceleration or when the
acceleration set button (8) is pressed. The value of the deceleration profile is displayed either
during deceleration or when the deceleration set button (9) is pressed.
In addition, it shows the temperature in the bowl of the centrifuge. When the centrifuge is at rest, the
set bowl temperature is displayed (°C). During a run, the actual bowl temperature is displayed (°C).
Keystroke sequence and description
Press the start button (12).
Press the stop button (10)
Press the pulse button (11) and hold. The centrifuge will accelerate the rotor to the speed setting of
the active program. When the button is released, the rotor will be decelerated to rest.
When the LED next to 'RPM' (18) is illuminated, the upper display shows speed values. To
increase/decrease the speed values, press on the corresponding up/down arrows.
When the LED next to 'G' (19) is illuminated, the upper display shows RCF values. To
increase/decrease the RCF values, press on the corresponding up/down arrows.
When using RCF as a control/display value, make sure the correct centrifugal radius is entered into
the control system (see below). If an incorrect radius value is in the control system, the RCF value
displayed will not be accurate.
When the LED next to 'TIME' (20) is illuminated, the middle display shows time values. To
increase/decrease the run time values, press on the corresponding up/down arrows.
When the LED next to 'RADIUS' (21) is illuminated, the middle display shows the value of the cen-
trifugal radius in millimeters. To increase/decrease the centrifugal radius, press on the correspon-
ding up/down arrows. This parameter can only be viewed and set while the centrifuge is at rest.
It is essential that this value be correct for the RCF control/display function to be accurate. The cor-
rect value of the centrifugal radius depends on the combination of rotor/buckets/adapters being
used.
