b.
Vary the position of your finger on the Fill Strip to ensure the piston load speed varies.
c.
Ensure that the Volume Remaining display on the head decreases.
10.
Press the Enable button, and press Reverse on the Fill Strip within five seconds.
a.
Ensure that the piston retracts.
b.
Vary the position of your finger on the Fill Strip to ensure the piston load speed varies.
c.
Ensure that the Volume Remaining display on the head increases.
d.
Retract the piston to its rear limit. The Volume Remaining should read “150mL”.
11.
From the Home tab, enter a protocol with the following parameters:
Volume - 20 mL
Flow Rate - 10 mL/s
Pressure Limit - 500 PSI
a.
Ensure the Injector Head displays these value.
12.
Select Arm Single to Arm the injector.
a.
Ensure that the display indicates that the injector is in the Armed state.
b.
Ensure that the Armed light on the injector head is on solid.
13.
Using the hand switch or foot switch, initiate an injection.
a.
Ensure that the Display Control Unit display indicates that the injector is in the
“Injecting” state and the Armed light on the injector head flashes.
b.
Confirm that the injection completes in approximately 2 seconds.
c.
Ensure that the Armed light on the Injector Head goes out.
d.
When the injection is complete, release the switch.
e.

a.
Select Arm Single to arm the injector.
b.
Use the hand switch or foot switch to initiate an injection.
c.
Release it within 2 seconds.
d.
Ensure the injection stops and disarms.
e.
Ensure a “Premature Termination” message displays in the Sentinel window.
15.
From the Home tab, select the Variable tab and enter a protocol with the following
parameters: Volume - 10mL, Flow Rate - 1 mL/s, Pressure Limit - 300 PSI
a.
Arm the system. the armed light should be solid while armed and the system should
initially beep.
b.
Initiate the Variable Flow Rate injection via the Hand Controller. Vary the flow during the
injection. Confirm that the rate can be varied from 0 to 1 mL/s. Volume delivered should
indicate 10 mL (if the injection is completed). No pressure limiting should occur.
c.
The flow rate of the delivery should change in accordance with Hand Controller trigger
position. The DCU should display instantaneous flow rate during injection.
d.
The armed light should switch from solid to flashing illumination during injection. The
injection should complete without error. If the system has sufficient fluid for another
injection, the system should return tot he armed state. If the system has insufficient
fluid, the unit will disarm at the end of the injection and display “Procedure Halt - Low
Volume” in the sentinel window.
16.
Retract the piston to its rear limit.
a.
Select either Arm Single or Arm Multiple to arm the injector.
b.
Open the drop front.
c.
Ensure that the system disarms.
d.
Close the drop front.
17.
Select either Arm Single or Arm Multiple to arm the injector.
a.
Press the Disarm button on the Display Control Unit.
b.
Ensure the system disarms.
