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

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

During the centrifugation run, the speed of the rotor or the RCF value resulting from this, the sample temperature (for
centrifuges with cooling only) and the time run will be 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


Release the key again to end the centrifugation run. Run- down is carried out with the selected run- down

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

During the centrifugation run, the speed of the rotor or the RCF value resulting from this, the sample temperature (for
centrifuges with cooling only) and the time run will be displayed.

Change the settings during the centrifugation run

It is not possible to modify settings during centrifuge operation if program linkages are being used.
The runtime, speed, relative centrifugal force (RCF),warm-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.

Integral RCF

The integral RCF is a measure for the effect of sedimentation (∫ n
centrifugation runs.
19.1

Query integral RCF

You can only query integral RCF if the integral RCF display is activated. See chapter "Activate or deactivate
integral RCF display".
The integral RCF is not saved. After starting the next centrifugation run or after switching off the device, the
integral RCF is deleted.
If the function, "Timing begins at speed" is selected, calculation of the integral RCF begins once the set
speed has been reached.
