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:
forward or reverse
• 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 Allegro Peristaltic
Pump 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 L, ml, µl or nl 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.
