overall percentage error
The maximum deviation of the delivered amount (overall mean
percentage error of flow rate) for 100U insulin is ≤ 30%*.
It is in the responsibility of the health care professional to
decide whether the accuracy of the flow rate is sufficient
for the according patient.
* The measurements were made at the minimum rate of 0,05U/h according to IEC 60601-2-24:2012 with an Accu-Chek Tender infusion set PC 17 / 110 at room
temperature.
