2. On the Set Target Volume or Time screen, select the Volume or Time button, as desired.
3. Enter the desired value using the keypad, or select the Maximum Volume button.
4. If the Units of Volume/Time are not correct for your application, choose the Units button to the right
of the parameter entry box. For the Units of Volume, this choice takes you to the Units Selection
screen. For the Units of Time option, this choice will toggle the button between sec (seconds) and
h:m:s (hours:minutes:seconds). To use the h:m:s option, enter your time value in hours, minutes and
seconds, separating each value with a colon.
5. If you are changing the Units of Volume, on the Units Selection screen, select the unit of measure (ml,
µ
l, nl or pl) as appropriate, then choose Accept to confirm your selection.
6. When all parameters are correctly set on the Set Target Volume or Time screen, choose Accept to

USING AN EZ PRO PRELOADED/USER-DEFINED METHOD
The Preloaded Methods and User-defined Methods each use the PHD ULTRA
™
’s integrated tools that guide
users through creation/editing of a custom Pump Control Method. Pump Control Methods consist of the
following set of operating parameters:
• The Method Name
• Syringe Specifications
• The set of Pump Operation Profile steps that describe how the pump will control the flow of material
for infusion or withdrawal operations
• Any additional commands to control the execution of the steps
• Any input/output (I/O) triggers/responses used to control external devices or respond to input signals
from external devices.
Both the Preloaded and User-Defined Methods offer the user the flexibility to apply pumping profiles other
than continuous rate infusion/withdrawal. The PHD ULTRA
™
offers a menu of advanced pumping profiles,
including:
• Constant Rate: a single continuous rate of flow
• Ramped Rate: a linearly changing flow rate between a starting and ending flow rate
• Stepped Rate: an evenly-stepped, changing flow rate between a starting and ending flow rate
• Pulsed Rate: an oscillating flow rate varying between a starting and a target rate
• Bolus Delivery: an infusion operation to occur for a specified volume or time. The default Infusion
Rate is the maximum permissible for the selected syringe, but it can be changed
• Concentration Infusion: a measured flow rate based on delivery of a specific dosage to a recipient
based on the recipient’s weight
• Autofill Cycling: continuous infuse-withdraw operation.
In addition, you have access to a variety of controls that allow the PHD ULTRA
™
to repeat, loop back or
jump forward in a Method, as well as send signals to external devices or react to signals received from
external devices. This package of pumping profiles and commands provides users with an extremely broad
array of applications that can be easily configured without the use of complex external programming.
The Preloaded Methods provide a starting set of Methods that define some commonly used application
protocols. These Methods can be edited and saved under a new name, or simply edited to fit your specific
requirements. Creating a new User-Defined Method permits you to leverage all the options available on the
PHD ULTRA
™
.
