Operation
Temperature adaptation during standstill

Sorvall Legend X1R

Continuous operation
If you selected continuous operation (see “Continuous operation” on page 4-6), you will have to stop
the centrifuge manually. Press the
key on the control panel. The centrifuge will be decelerated at
the designated rate. The message
End
will illuminate, and after pressing the
key, the lid will open
and you can remove the centrifuged material.
Temperature adaptation during standstill
The temperature cannot be adapted until the rotor has been positively identified. For this, the
centrifuge must have accelerated to over 500 rpm. The speed display will then show
End
.
When the rotor is not recognized (lid closed and
key not yet pressed, speed display
0
), the
centrifuge responds by ensuring that the sample cannot freeze regardless of the rotor being used.
Short-term centrifugation
For short-term centrifuging, the Sorvall Legend X1R has a PULSE- function.
By holding down the
key, spinning will start and continue until the key is let go.
The centrifuge accelerates and brakes at maximum power. Any rpm or RCF entered beforehand is
overridden.
Check carefully whether you have to maintain a certain speed for your application.
During the acceleration process, time is counted forwards in seconds. The reading stays displayed until
the centrifuge lid is opened.
Removing the rotor
To remove the rotor, proceed as follows:
1.
Open the centrifuge lid.
2.
Grab the rotor handle with both hands and press against the green
Auto-Lock
key. At the same
time, pull the rotor directly upwards with both hands and remove it from the centrifuge spindle.
Make sure not to tilt the rotor while doing this.
Note
The centrifuge accelerates to maximum speed, regardless of which rotor was installed.
