After expiration of the time or with truncation of the centrifugation run by pushing the key
down is effected with the selected brake step. The brake step is displayed.
During the centrifugation run the rotational speed of the rotor or the subsequently resulting RCF value, the sample
temperature (only in centrifuges with cooling) and the remaining time will be displayed. After the centrifuge has ended
its run and the rotor has come to a halt, the lid opens automatically on centrifuges without cooling.

During the centrifugation run the rotational speed of the rotor or the subsequently resulting RCF value, the sample
temperature (only in centrifuges with cooling) and the expired time will be displayed. After the centrifuge has ended
its run and the rotor has come to a halt, the lid opens automatically on centrifuges without cooling.

selected brake step. The brake step is displayed.
During the centrifugation run the rotational speed of the rotor or the subsequently resulting RCF value, the sample
temperature (only in centrifuges with cooling) and the expired time will be displayed. After the centrifuge has ended
its run and the rotor has come to a halt, the lid opens automatically on centrifuges without cooling.

Emergency Stop

•
Press the key
STOP / OPEN
With Emergency Stop the run-down is effected with brake step 9 (shortest run-down time). Brake step 9 is displayed.
If brake step 0 was pre-selected, the run-down time is technically longer than with brake step 9.

Acoustic Signal

The acoustic signal sounds:
•
Upon the appearance of a disturbance in 2 second intervals.
•
After completion of a centrifugation run and rotor standstill in 30 second intervals.
The acoustic signal is stopped by opening the lid or pressing any key.
The signal after completion of the centrifugation run can be activated or deactivated in the following manner, if the
rotor is at standstill:
•
Hold down the key
SELECT
After 8 seconds, SOUND / BELL appears in the display.
•
Set using the knob OFF or ON.
•
Press the key
START / IMPULS
As confirmation, ∗∗∗ ok ∗∗∗ will be displayed for a short period.

Recall hours of operation

Recall hours of operation is only possible during rotor standstill.
•
Hold down the key
