Constant Flow; Constant Pressure - Teledyne D series Installation And Operation Manual

D Series Syringe Pumps
Section 3 Basic Programming and Operation

3.10.1 Constant Flow

3.10.2 Constant Pressure

3-16
The constant pressure mode is used when the application of fixed
pressure throughout the pumping operation is required. The
pump will maintain the desired pressure by positive or negative
displacement of the piston.
Programmed Gradient – Refer to Section 4
In the programmed gradient mode, the pump can provide the fol-
lowing types of gradient:
• Two-pump concentration gradient on pumps A and B
• Single-pump linear pressure gradients on pump A
• Single-pump flow programs on pump A
Dispense – For applications requiring delivery of a specific
volume. Refer to Section 3.10.3.
Refill – Refer to Section 3.4.3.
You can set the refill rate and change it when in refill mode.
To set constant flow operation, use the following procedure:
1. Press CONST FLOW. "CFa" will be displayed in the upper
left corner of the screen. This denotes that you will be
defining constant flow parameters for pump A. If you wish
to define parameters for pump B, C, or D, press softkey D,
select pump, and then press softkey A, B, C, or D to select
pump A, B, C, or D respectively.
Note
If the main menu is displayed, you must press D under CONST
FLOW.
2. Press A to change the flow rate. The words ENTER FLOW
RATE will flash on the screen.
3. Use the number keys to enter the desired flow rate.
Note
If you make an error, press CLEAR ENTRY to delete one char-
acter at a time.
4. Press ENTER once the desired flow rate is displayed.
5. Press RUN to begin pump operation.
Programming a constant pressure operation only requires a few
keystrokes. Use the following procedure:
1. Press CONST PRESS; CPa will be displayed in the upper
left corner of the screen. This denotes that you will be
defining constant pressure parameters for pump A. If you
