Stepped Profile

The Stepped Rate profile is used to create an increasing

or decreasing flow rate that varies in a series of equal

steps between a starting and ending flow rate.

Stepped Rate Pump Operation Profile

When creating or editing a Stepped Rate profile, you will

define four primary operating parameters:

The Flow Mode defining the direction of flow:

infuse or withdraw

The Flow Rate at the beginning and end of the

pumping cycle

The Target Time that determines the total length of

time over which the stepped profile will be

calculated

The Number of Steps that will be created in

the profile

During a Stepped Rate profile, the KDS Legato 200

Series calculates a series of equal rate increases that will

vary the flow from the starting value to the ending value.

You enter the Number of Steps you want to use. The

Target Time defines the total length of pumping time, with

the Target Time value divided equally into each stepped

rate. A Stepped Rate profile can be applied to an

increasing or decreasing rate application.

When creating or editing a Stepped Rate profile, you can

set the rate in ml, µl, nl or pl units of volume using sec or

h:m:s (hours:minutes:seconds) 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 screen.
