15.1 Centrifugation with pre-set time
• Adjusting time or recall a programme with pre-set time (see Chapter "Entering centrifugation parameter" or
"Programme recall").
• Press the key
START
. The rotation display lights up as long as the rotor is turning.
• After expiration of the time or with truncation of the centrifugation run by pushing the key
STOP
, the run-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.
15.2 Continuous run
• Adjusting the symbol ∞ or recall a continuous run programme (see Chapter "Entering centrifugation parameter"
or "Programme recall").
• Press the key
START
. The rotation display lights up as long as the rotor is turning. The time metering begins
at 00:00.
• Press the key
STOP
in order to stop the centrifugation run. The run-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 expired time will be displayed.
15.3 Short-term centrifugation
• Hold down the key
IMPULS
. The rotation display lights up as long as the rotor is turning.
• Let go of the key
IMPULS
again in order to stop the centrifugation run. The run-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 expired time will be displayed.
16 Emergency Stop
• Press the key
STOP
twice.
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.
17 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
for 8 seconds.
After 8 seconds, SOUND / BELL appears in the display.
• Set OFF or ON with the key or .
• Press the key
START
in order to store the setting.
As confirmation, ∗∗∗ ok ∗∗∗ will be displayed for a short period.
18 Recall hours of operation
Recall hours of operation is only possible during rotor standstill.
• Hold down the key
for 8 seconds.
After 8 seconds, SOUND / BELL appears in the display.
• Press the key
once again.
The centrifuge’s hours of operation (CONTROL: ) are displayed.
• Press the key
or to exit the hours of operation recall.
