These graphs show the accuracy and
uniformity of flow over time. Take into
account:
Q
The delivery behaviour and the delivery
accuracy are fundamentally affected
by the disposable item used.
Note:
The system accuracy is normally ±5%
of the volume, measured using the trumpet
curve test method according to IEC 60601-
2-24 at a rate of 1 ml/h (at 20 °C ± 2 °C)
and using the recommended disposable
item.
