When entering a function with associated data, such as with the ‘Pause’ in Phase 5 or the ‘Loop’ in Phase 6, the
function is entered in 2 steps. First select the function and store it. Then enter the associated data.

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.
