The PHD ULTRA

Methods contain the detailed parameters required to control the pump for infuse or
withdraw operation. This section describes the basic operation of the pump using a stored Method.
SELECTING A METHOD

Selection screen.

pump.
2. From the list of available Methods, double tap the desired Method. If the Method is not displayed in the
list, you can use the Scroll Up/Down buttons or Page Up/Down buttons to advance the list up/down
as needed. Be sure to confirm your selection by pressing the button containing the Method name a
second time, or choosing Accept. You will be returned to the Quick Start screen with the Method
Select button now displaying the desired Method.
CONFIRMING METHOD PARAMETERS
3. With the desired Method displayed in the Method Select button, verify that the proper syringe
information is set. The currently defined syringe settings are displayed in the Syringe Select button. If
the syringe information is not correct, follow the procedure for setting syringe parameters defined
previously in the Syringe Selection section of this manual.
4. Verify that the Rate and Volume/Time settings are properly set. If changes are required, refer to the
procedures described later in the Quick Start Method Variables section of this manual.
5. With all Method parameters set as desired, check to see if the Run button is active.
6. If any required parameters are not set or are improperly set (e.g. a value is out-of-range based on
syringe selection or other condition), the Run button will be inactive (grayed out). You must have all
required parameters validly defined before the Method can be started.
