Continuous Run
During the continuous run, the runtime of the centrifuge is unlimited
and must be stopped manually. The centrifuge accelerates during the
continuous run until the set speed is reached.
Starting with the time setting 0:10, turn the knob counter-
clockwise
or starting with the time setting 11:59, turn the knob clockwise to
the next setting. The message “cont” and the symbol " " will be
displayed (Fig. 6.8).

6.2.3.6 Speed
In the upper section of the field, the set speed of the centrifuge is
displayed. The actual speed is displayed below this value. The values
are stated in revolutions per minute (rpm) and depend on the RCF
values (see 11.3 " Formulae – Mathematical Relations "). The
maximum speed values depend on the rotor that is used. When the
maximum permissible speed of the rotor is reached, the “max” display
lights up.
To preselect a speed value:
Turn the left function key until “set” appears in front of the
parameter “Speed” on the display (Fig. 6.9).
Select the option by pressing or turning the right function key.
“Set” will now flash.
Turn the right function key until the desired value is displayed.
Press the right function key to confirm the selected value. If this
is not done, the value will be automatically reset to the last
setting.
It is possible to change the speed value during the centrifugation run.

Changing the Speed Increments
In order to change the speed in steps of 1 rpm (instead of in steps of
100 rpm):
Keep the stop key pressed while setting the desired speed with
the right function key.
