Operation Manual 18 - 105
Q
When a fault caution, hold, or stop is detected, the injection will stop within 5mL.
Q
Once the system has disarmed, a tone sounds and a stall message appears on the display.
18.8 Fluid Delivery Performance
18.9 System Fluid Performance
The performance of the injection system has been tested with disposables supplied by Bayer and the catheters noted in Table
18 - 2.
18.9.1 Factors Affecting Flow Rates
The injector’s ability to generate pressure is only one factor affecting maximum flow rates. Other factors include:
Q
Catheter diameter
Q
Viscosity (thickness) of the fluid
Q
Tube length
Q
Number of tubing sections
Q
Tube diameter
Q
Temperature of the fluid, tube, and syringes during the injection
Q
Maximum pressure setting on the injector
If problems are experienced achieving the desired flow rate, please contact a Clinical representative for suggestions that may
increase it.

Fluid
Volume Accuracy
Single Syringe A Injection:
+/- (1% + 0.2ml) of the programmed contrast volume for volumes ≤ 15.0 ml
+/- (1% + 0.3ml) of the programmed contrast volume for volumes >15.0 ml
Single Syringe B Injection:
+/- (5% + 0.1mL)
Flow Rate Accuracy
Single Syringe Injection:
+/- (10% + 0.005 mL/s) when rate is 0.01 to 0.99 mL/s
+/- (10% + 0.02 mL/s) when rate is 1 to 10 mL/s
NOTE:
The injection system performs within the defined flow rate
accuracy specifications over steady state. Steady state is
measured over 1 second or 10 mL, whichever is greater.
Pause Accuracy +/- (5% + 0.2 second)
KVO Volume Accuracy +/- 0.05 mL, averaged over 10 consecutive boluses
KVO Flow Rate Accuracy 1 mL/s +/- 0.2 mL/s
