2. Acceptance of changes during the centrifugation run.
Stop centrifugation run.
STOP
The rotor decelerates with the preset run-down parameters. Pressing the key twice will initiate an emergency
stop.
Select program location, parameter PROG-Nr.
PROG
Calling up of programs.
RCL
Saving of programs.
STO
89 programs can be saved (program locations 1 to 89). Note: The program locations "----" and 90 to 99 are
used as automatic buffers (see Chapter "Automatic buffer"). No programs can be saved in these program
locations.

Entering centrifugation parameters

It is only possible to enter a parameter when the input field is displayed inversely (dark background). An
inverse input field will go off automatically after 10 seconds.

Running time

17.1.1

Time selection


Press the key repeatedly until the parameter t/min: or t/ :sec is displayed. The input field will be displayed
t
inversely.

Set the desired value by means of the control knob
17.1.2

Continuous running


Select the parameters t/min: and t/ :sec one after the other (see Chapter "Time selection"), and set both to zero
using the control knob
17.2

Speed (RPM)


Press the key repeatedly until the parameter RPM is displayed and the input field is shown inversely.
