Translation of the original operating manual
Rapid cooling program "RAPID TEMP"
Precooling at a standstill may distort the measurement results and
subsequently cause increased wear of the mechanical components.
This is why the centrifuge has a special program that precools the
centrifuge rapidly under defined conditions:
Turn the left function key until “run” appears in the display field
(Fig. 6.14).
Select the option by pressing or turning the right function key.
"Run" will now flash.
Turn the right function key until "PrC" is displayed.
Press the right function key to confirm the selected value. I The
display shows 1/3 of the maximum rotor speed and the
corresponding RCF value. The message “cont” for contiuous run
and the symbol " " will be displayed in the time field.
Start the centrifuge by pressing the start key.
Fig. 6.14:
Rapid cooling program
"RAPID_TEMP"
The program will only be loaded if the actual temperature is above
the set temperature.
The temperature value indicates the air temperature in the rotor
chamber. The rotor – depending on its type – will reach this
temperature only after a corresponding precooling time
The program runs until the set value is reached. Then, a sound signal
is issued, and the standstill colling is activated. The program that was
set beforehand will be reloaded.
Press the stop key to determinate the rapid cooling program
prematurely.
An entry will interrupt the rapid cooling program. There will be no
message when the set temperature is reached. If no new runtime is
entered, the centrifuge will continue to run infinitely (continuous run).
