Immediate display of centrifugation data after switch-on.

 Switch on the power supply. (Switch setting ).

The first time the display changes optically, (inverse display) press any key and keep it held down. The
centrifugation data is displayed immediately.

Cooling (only in centrifuges with cooling)

The temperature set-point can be adjusted from -20°C to +40°C / -4°F to +104°F. The lowest obtainable temperature
is dependent on the rotor (see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories").
34.1

Standby-cooling

When the rotor is at a standstill, with the lid and hatch closed, the centrifuging chamber is cooled to the preselected
temperature if this is lower than 20°C / 68°F.
During the standby cooling, the preset temperature is displayed.
34.2

Precooling of the rotor

For quick precooling of the unloaded rotor and the accessories, it is a good idea to do a centrifugation run with
the continuous operation setting and a speed of about 20% of the maximum rotor speed.
A centrifugation run for pre-cooling the rotor can only be started via the interface (key position "LOCK 2"). The
functions of the various key positions are described in the "Key-operated switch" chapter.

Start the centrifugation run via the interface. The LED in the

During the centrifugation run, the rotor speed or the RCF value, the temperature in the centrifuging chamber and the
remaining or elapsed time are displayed.
34.3

Time-controlled cooling

If necessary it can be set so that cooling begins after a certain amount of time once centrifugation run has been
started.
The delay time can be set in 1-second increments from 15 to 900 seconds. If no time delay is required, set to "0". No
delay time is set ex works.
When the rotor is at a standstill, the delay time can be set as follows:
This setting can only be made via the operating unit (key position "0" or "LOCK 2"). The functions of the
various key positions are described in the "Key-operated switch" chapter.
