onstant Rate Pump Operation Profile
When creating or editing a Constant Rate profile, you
will define three primary operating parameters:
• The Flow Mode defining the direction of flow:
forward or reverse
• The Flow Rate to define the rate of uptake or
dispensing
• The Target Volume or Run Time that determine how
long the pump will operate at the set rate
When creating or editing a Constant Rate profile, you
can set the rate in L, ml, µl or nl units of volume using sec,
min or hr as the units of time. The system automatically
calculates a minimum and maximum flow rate based on
the tubing size selected or custom-defined. The min/max
values are made available as button selection options on
the Rate screen.
