General Description
Operation of the pumps is simplified by using a keypad to select features from a menu on the
alphanumeric display.
All control functions are performed automatically by the pump microcontroller and are based
on the syringe diameter and linear motion of the pusher block to deliver a known volume.
After entering the syringe diameter, either directly or from a table in memory, a dispense
volume and flow rate can be entered, and then all calibration and control functions are
performed by the pump automatically.

Features
1) Syringe identification
Look up Table
The pump contains a table of standard syringes arranged by manufacturer, material
and size. Once the syringe is identified in the table the pump automatically enters the
appropriate diameter.
Direct Entry
If the syringe used is not included in the table, the internal diameter of the syringe
barrel can be measured in millimeters and entered directly from the keypad.
2)
INFUSION AND REFILL RATES
The infusion rate and, where applicable, the withdrawal rate can be set independently
and can be changed while the pump is running. After the operating mode selection is
made the program will prompt only for the relevant rates associated with that mode.
3)
VOLUME
A target volume can be entered for infusion and refill independently, and the pump
automatically stops when this volume is reached. The pump displays an initial volume of
zero and increases as the dispense proceeds to the target volume. The target volume
can be reviewed or changed as the pump continues to operate.
