6.4.1 Centrifugation in continuous operation
Personnel:
■ Trained user
1. If required: Press the
[RCF]
button.
🡆
The parameter RCF (
‘>RCF<’
) or RPM (
‘RPM’
) is displayed. Press
the
[RCF]
button to toggle between the two parameters.
2.
Enter the desired speed (RPM) or relative centrifugal force (RCF).
See ⮫
Chapter 7.2 ‘Programming’ on page 27
.
3. Set the parameters t/min and t/sec to zero.
🡆
‘--:--’
is displayed.

Chapter 7.2 ‘Programming’ on page 27
.
4. Press the
[START/PULSE]
button.
🡆 The centrifugation run is started.
The timing starts at
‘0:00’
.
The rotor speed or the resulting RCF value and the elapsed time
are displayed during the centrifugation run.
5.
Press the
[STOP/OPEN]
button to cancel the centrifugation run.
🡆
Ramp-down takes place with the set brake level. The brake level is
displayed.
When the rotor is at a standstill, the lid opens, an audible signal
sounds and the remaining number of run cycles (centrifugation
runs) is displayed.
