* The measurements were made at a medium basal rate of 1.0 U / h according
to IEC 60601-2-24:1998 with an Accu-Chek Tender infusion
set PC 17 / 110 at room temperature.
The maximum deviation of the delivered amount (overall mean
percentage ow error) for U100 insulin is ≤ ± 5 %*, where your
Accu-Chek Spirit Combo insulin pump is located ≤ 1 m (3.3 feet)
above / below the infusion site.
