G. Accuracy of Flow Rate
This graph shows the ow rate during the stabilization period. Measurements were made at a basal rate of 1U/h, in
accordance to IEC 60601-2-24:1998 using an Aviator Insulin Reservoir and a Unomedical Comfort infusion set.

At the minimum rate of 0.05 U/h (0.0005 mL/h), setup errors associated with the IEC 60602-2-24 test are too large
to accurately determine the ow rate of the pump. An alternate test method was used which determines delivery
accuracy by analyzing the movement of drive motor, as reported by an encoder on the motor shaft. Actual insulin
ow rate may be less accurate.
This graph shows the calculated ow rate during the stabilization period. Encoder data was collected at a basal rate
of 0.05U/h.
