Operation
3-6
When run parameters for a rotor have been entered, as described below,
they will be retained in the centrifuge memory and can be recalled by
simply entering the rotor number. The recalled program can then be used
for the current run or can be altered as required.
Selecting a Rotor Number
Each rotor that can be run in the centrifuge has a rotor number; the number
is engraved on the rotor (and on the lid of fixed angle rotors). The centri-
fuge internal memory contains a list of all rotors that can be run in the
centrifuge, together with acceptable run parameters for each rotor. If you
enter an unauthorized rotor number then press the [
START
] key, an error
message will be displayed and the run will be aborted shortly after the rotor
starts spinning.
1. Press the [
ROTOR
] key.
A rotor number (the last rotor previously centrifuged) will appear on
the SPEED display.
2. Press the
▲
or
▼
cursor key until the number of the rotor in use is
displayed.
3. Press [
ENTER
].
Nominal parameter values (time, temperature, speed, acceleration and
deceleration curves) for the selected rotor will be displayed. You can
use these parameters or set new values for the run.
Setting Run Speed
Centrifuge speed can be set for up to the maximum rated speed of the
selected rotor. Either revolutions per minute (rpm) or relative centrifugal
field (RCF) can be used to select speed. During centrifugation, the SPEED
display indicates the actual run speed of the rotor.
