Note: Graph is representative only.
Pumping rate increments and decrements in steps.

Continuously ramp up and down the pumping rate. Starting at 200 ml/min, the pumping rate will
increment to 250 ml/min in 1.0 ml/min steps after every 0.1 ml has been dispensed. Then the pumping
rate will decrement to 150 ml/min in 1.0 ml/min steps after every 0.1 ml has been dispensed. Finally, the
pumping rate is incremented back to 200 ml/min in 1.0 ml/min steps after every 0.1 ml has been
dispensed, then the process is repeated.
