Continuous operation


Set the minutes, seconds and hours to "0" or start a continual run program (see chapter "Enter centrifugation
parameter" or " Calling up programs").

Press the key. The LED in the
START
The time count starts from 00:00.

Press the key to end the centrifugation run. Run- down is carried out with the selected run- down
OPEN / STOP
parameters. The run-down parameter is displayed e.g. 9. The right-hand LED in the
the rotor has come to a standstill, the LED in the
right-hand LED in the
OPEN / STOP
continues blinking until the lid is opened.
During the centrifugation run, the rotor speed or the RCF value, the temperature in the centrifuging chamber (only for
centrifuge with cooling), and the elapsed time are displayed.

Short-time centrifugation

A short-time centrifugation is not possible if program linkages are being used.

Keep the key pressed. The LED in the
START
subsequently lit. The time count starts from 00:00.

Release the key again to end the centrifugation run. Run- down is carried out with the selected run- down
START
parameters. The run-down parameter is displayed e.g. 9. The right-hand LED in the
the rotor has come to a standstill, the LED in the
right-hand LED in the
OPEN / STOP
continues blinking until the lid is opened.
During the centrifugation run, the rotor speed or the RCF value, the temperature in the centrifuging chamber (only for
centrifuge with cooling), and the elapsed time are displayed.

Change the settings during the centrifugation run

It is not possible to change centrifugation parameters during the centrifugation run if program linkages are
used or if a program lock is set. The functions of the various program locks are described in the chapter
"Setting program locks".
The runtime, speed, relative centrifugal force (RCF), start-up and run-out parameters as well as temperature (only in
centrifuges with cooling) can be changed during the centrifugation run.

Change the value of the desired parameter (see chapter, "Enter centrifugation parameter").
The changed setting is saved at program place "0" (see chapter "Automatic temporary storage"). The original
program is not overwritten. The program place number is displayed in parentheses ().This means that the
centrifugation data in the display no longer corresponds to the centrifugation data from the program place that
has been saved.
