Note: Graph is representative only.
Pumping rate increments and decrements in steps.
Continuously ramp up and down the pumping rate. Starting at 200 mL/hr, the pumping rate will increment to
250 mL/hr in 1.0 mL/hr steps after every 0.1 mL has been dispensed. Then the pumping rate will decrement to
150 mL/hr in 1.0 mL/hr steps after every 0.1 mL has been dispensed. Finally, the pumping rate is incremented
back to 200 mL/hr in 1.0 mL/hr steps after every 0.1 mL has been dispensed, then the process is repeated.
