* The measurements were made at the minimum rate of 0.02 U/h according to IEC 60601-2-24:1998 with an Accu-Chek Insight Adapter and Tubing transfer set
100 cm at room temperature.
The maximum deviation of the delivered amount (overall mean
percentage flow Error) for U100 insulin is ≤ ±60 %*.
It is in the responsibility of the healthcare professional to
decide whether the accuracy of the flow rate is sucient for
the according patient.
