The preselected total runtime is displayed in the lower line of the display.
During centrifugation, the remaining runtime is displayed. The runtime of
the centrifuge can be set at one-second-intervals up to 99 minutes and 59
seconds.
•
To select a runtime, press the set key repeatedly until the time unit
flashes on the display.
•
Select the desired runtime by pressing the arrow keys.
•
Confirm the selection by pressing the start/stop key.
The data will also be accepted and saved after approx. 20 seconds if no
other key is pressed within this time period.
The preselected runtime can be changed during centrifugation.
•
Press the "set" key repeatedly until the time unit flashes on the display.
•
Change the desired runtime by pressing the arrow keys. The
parameters will be accepted immediately.
If the centrifugation time is changed during the run, the centrifuge will run
for the entire new time and will disregard the previous runtime that has
already elapsed.
During the short run, the centrifuge accelerates at maximum power until the
maximum speed is reached.
•
Keep the quick run key pressed during the short run.
The message "short run" and the duration of the short run are displayed.
When the quick run key is released, the centrifuge decelerates at maximum
power to a standstill.
After the short run, the lid unlocks automatically and the program that was
set beforehand is displayed again.
