but pressing and holding the START/STOP button serves the same function.
•
When the
QUICK RUN
key is pressed, the rotor accelerates at a maximum rate to the set speed
and continues to spin as long as long as the
QUICK RUN
key is pressed. (The current run time,
acceleration, and deceleration settings are overridden by the short run function.) When the
QUICK RUN
key is released, the rotor begins decelerating to 0 RPM using maximum deceleration.

QUICK RUN
key is pressed, the
TIME
display begins displaying the elapsed seconds.
When the
QUICK RUN
key is released, the seconds stop accumulating.

The centrifuge memory retains the parameters of the last run performed before the
QUICK RUN
key was pressed. At the end of a quick run, after the centrifuge door is opened and closed the
previous run parameters are displayed.
