Program "Rapid Temp"
The centrifuge has a special "Rapid Temp" program that precools the
centrifuge rapidly under defined conditions.
• Select the program with the aid of the menu item "run Prog" (see
chapter 6.3.3.2 - "Loading a program"). The speed display shows
⅓ of
the maximum rotor speed, the deceleration (brake) and acceleration
curves correspond to curve 9 and the runtime field indicates "Cont"
(continuous run). "Rapid Temp"
will flash next to the “run” display.

NOTE
The program will only be loaded if the actual temperature is above the set
temperature.
• Press the start button in order to start the rapid cooling process.
• During the rapid cooling process, the set temperature can be modified
within the range below the actual temperature.
The "Rapid Temp" program will be stopped under the following conditions:
• The set value is reached. The program will stop with a sound signal if
this function is activated.
• The stop button is pressed. The program will be stopped prematurely.
• A parameter is changed (except for the temperature and
rotors/buckets). In this case, the program will be aborted.
After the stop, the previous program will be reloaded or the changed
parameters will be adopted as the new settings.
NOTE
The automatic lid opening function ("AutoOpen") is suppressed after a
rapid cooling phase in order to prevent the system from reheating.
NOTE
If the "Rapid Temp" program is used, the temperature of the unloaded
aluminium bucket will be displayed. If samples, which have not been
precooled, are placed into the buckets
after a “Rapid Temp” run, the
displayed temperature will deviate from the actual sample temperature.
