The Quick Start Infuse Rate and Withdraw Rate Select functions define the rate of pumping while infusing
or withdrawing liquids respectively. The two functions are controlled identically, so we have described the
operation here only once.
When adjusting the Infuse Rate, you can set the rate in ml, µl, nl or pl units of volume and use sec, min or
hr as the units of time. The system automatically calculates a minimum and maximum flow rate based on
the syringe selected or custom-defined. The min/max values are made available as button selection options
on the Set Infuse and Withdraw Rate screens.

NOTE: The following instructions describe setting the Infuse Rate. The instructions are
the same for Withdraw Rate. On an Infuse/Withdraw combination Method, you can set
both rates on a single screen by toggling between the two rate options using the Infuse
Rate or Withdraw Rate buttons at the top of the screen.
