Description
System Keys
Centrifuge operation is controlled through the system keys. Each
key, except [
PULSE
], has an LED in the upper left corner that lights
to indicate operational readiness.
[
OPEN DOOR
]
Unlocks the electromechanical door lock. The instrument will not
accept this command if the rotor is spinning.
[
FAST STOP
]
Causes the centrifuge to decelerate to a complete stop at the maxi-
mum rate; deceleration cannot be interrupted—the centrifuge can be
restarted only after the rotor stops and the door is opened and closed.
[
STOP
]
Can be pressed at any time to terminate a run according to the
selected deceleration rate. Deceleration can be terminated and the
centrifuge restarted by pressing [
START
] again.
[
START
]
Causes a timed or continuous run to begin; can also be used to abort
deceleration and restart the centrifuge.
[
PULSE
]
Causes the rotor to accelerate to set speed for short-duration runs (as
long as the key is pressed). Deceleration, at maximum rate, begins
when the key is released.
Parameter Keys
These keys are used to set up the run. Except for the cursor and
[
ENTER
] keys, parameter keys are located beneath the applicable
digital displays, which show the parameter values as they are input.
Each key (except the cursor keys) has an LED in the upper left corner
that lights to indicate operational readiness. The LEDs also blink if an
incorrect parameter is entered.
[
RPM
]
Causes the last digit in the
SPEED
display (0) to flash, indicating that
speed can be entered in rpm (revolutions per minute). Corresponding
RCF (relative centrifugal force) is calculated and can be displayed
during the run.
[
RCF
]
Selects speed setting by RCF; the corresponding rpm is automatically
calculated and displayed during the run. If this key is pressed during
the run, the
SPEED
display shows the RCF value.
[
ROTOR
]
When this key is pressed the number of the rotor used in the previous
run is shown on the
SPEED
display. The list can be scrolled through,
using the cursor keys, to select a rotor.
