Self test Dual microprocessors independently test each other.
Maximum over infusion Under a single-fault condition, the maximum over
infusion that may occur is 12.5% over the selected
flow rate. Larger inaccuracies are detected by the
pump, and cause it to stop infusing and to alarm.
Air detect system Air bubbles are detected by electronic opto-
encoder detection device (with self-checking
sensors) located on cassette housing.
Accuracy ± 2% of displayed rate and volume to be infused.
The quoted accuracy is ±2% for a long-term
infusion.
Below rates of 1 mL/h this accuracy may not be
achieved for a short-term infusion.
During the total infusion time the accuracy
averages out (see trumpet curves in this
chapter).
Accuracy measurement equipment
50 mL glass measurement burette graduated in
0.1 mL increments and traceable to National
Institute of Standards and Technology or
appropriate international standards bureau.
Test solution Sterile water or normal saline at room
temperature (70°F ±5°/21°C ±3°).
Graseby standard (primary), 20 drops/mL, non-
checkvalve administration set (8C820).
Testing conditions
Model 3000/500 fluid level in the solution container 46 cm (18
inches) above top of the pump, rate set at
999 mL/h and volume to be infused of 49 mL.
Micro 3100/505 fluid level in the solution container 46 cm
(18 inches) above top of the pump, rate set at
99.9 mL/h and volume to be infused of 25.0 mL.
