Acceleration and deceleration curves
Acceleration
This function is used to select an acceleration curve. The system offers 10
fixed, programmed acceleration curves (curves 0-9).
Brake
This function is used in order to select a curve that decelerates the
centrifuge to a standstill. Deceleration curves are inverted images of the
acceleration curves and are labelled with identical numbers. Deceleration
curve no. 0 represents a brakeless deceleration.
