Operation
• Deceleration rate can be changed until deceleration begins. (The
deceleration rate cannot be changed while the rotor is
decelerating.)
Use the parameter keys as described under SETTING RUN PARAM-
ETERS, above. You must press [
ENTER
] after you input each parame-
ter change. For example, you would change run speed during
centrifugation as follows.

The
SPEED
display flashes.
2. Press [
S

T
]
until
the selected speed appears.
3. Press [
ENTER
].
The current run speed will be displayed, changing to the new value as
the rotor accelerates or decelerates to the new speed selected. The
centrifuge will automatically calculate the corresponding RCF.
STOPPING A RUN
A timed run ends automatically when the
TIME
display counts down
to zero. To end a timed or continuous run in progress for any reason:
Action

1. Press [
STOP
].
Normal deceleration begins, as selected by the deceleration rate.
(or)
[
FAST STOP

Deceleration begins at the maximum rate (see Table 3-1). Decelera-
tion cannot be interrupted; the centrifuge can be restarted only after
the rotor comes to a complete stop and the door is opened and closed.
