5.3.1
Time
The runtime of the centrifuge can be set at different intervals in a range from 10
seconds to 11 hours and 59 minutes.
To select the desired centrifugation time:
•
Turn the left rotary knob until “set” appears in the lower left area of the display
(Fig 5.11).
•
Select the option by pressing or turning the right rotary knob. “Set” will now
flash.
•
Turn the right rotary knob until the desired duration is displayed.
•
Press the right rotary knob or the start key in order to confirm the input. If this
is not done, the value will be automatically reset to the last setting.
After 11:59 min, the display changes from “min:sec“ to “hrs:min“. The time can
then be changed in steps of 10 minutes.
It is also possible to change the runtime during the centrifugation run.
Attention!
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.
5.3.1.1 Changing the Time Increments
In order to change the time in steps of 1 second (instead of in steps of 10
seconds in the min:sec mode) or in steps of 1 minute (instead of in steps of 10
minutes in the hrs:min mode):
•
Keep the stop key pressed while setting the desired runtime with the right
rotary knob.
