By pressing this key, you decrease the set value of selected opera-
tion parameter for one step. By pressing and holding this key, the
value is decreasing quickly.
By pressing this key, you select operation parameters in the right
direction.
By pressing and holding this key, you perform the fast spin. The
centrifuge runs for as long as you hold the key pressed. Time of
run in seconds is displayed and message RUN is blinking on the
display. The acceleration and braking levels are fixed to 9 (the
highest), and they can't be changed. When you release the key,
the braking procedure of the rotor is activated, and the centrifuge
stops.
SHORT PRESS: By pressing this key, you open the lid of the centri-
fuge. When the lid opens, LID indicator turns off. When closing the
lid, press it down with your hands, until it locks up. When the lid is
closed, LID indicator turns on. LID indicator also turns off during
the run of the centrifuge and thus indicates that you can't open
the lid during the run.
LONG PRESS: By pressing and holding this key, you set the lid latch
to initial position. This is needed in case of power failure during
the opening of the lid, when lid latch motor stops in undefined
position. When power returns, it could happen that you can't
open or close the lid. If this happens, press the key for approxi-
mately five seconds, until you hear the sound of lid latch motor,
then release it. After that, you will be able to open and close the
lid normally
By pressing this key, you start the run of the centrifuge. Message
RUN appears on the display and thus indicates that the centrifuge
is running. During acceleration of the rotor, acceleration level AcX
is displayed, and then the selected operation parameter displays.
At the end of the set running time or manual stopping of the
centrifuge, the braking procedure of the rotor is activated, and the
centrifuge stops. The next run is possible, when the rotor stops
completely.
By pressing this key, you stop the run of the centrifuge. During
deceleration of the rotor, deceleration level brX is displayed, and
when the centrifuge stops, selected operation parameter displays,
and message RUN turns off.
