rotary knobs and indicates the operating statuses.
5.1.6 Electronic System
The microprocessor-controlled electronic system ensures a wide range of
adaptations of the centrifuge for various tasks. The following parameters can be
set:
• Speed in steps of 100 or 1 rpm
• Relative centrifugal force RCF in steps of 1 or 10 x g
• Time between 10 sec an 11h 59min max.
• Continuous run
• Short run
• Rotor preselection
• Acceleration and deceleration curves
• Storage and call-up of programs
