on page 49. The run-down parameter is displayed, e.g. ‘9’. The
right LED in the

7.2.6
Precooling of the rotor
To quickly precool the unloaded rotor and accessories, a
centrifugation run at a speed of approx. 20 % of the max-
imum rotor speed is recommended. Precooling is done
automatically with the ‘PREC’ (PRECOOLING) program.
Precooling is not possible if program linkages are being
used.
To set the precooling, proceed as follows:
1.
Close the lid.
2.
Press the
[Rotor precooling] key.
🡆
The LED in the
[Rotor precooling] key flashes until the rotor is read
in; then the LED is illuminated.
You can make changes to the ‘PREC’ program in
the same way as all program changes are made.
The ‘PREC’ program is located after program
location 98.
