A.6 Infusion Accuracy Curve and Trumpet Curve
The following typical infusion accuracy table expresses performance after infusion
has started and infusion fluctuations occurring within a certain period of time after
normal infusion flow volumes have been reached. The infusion accuracy table is for
reference only, detailed infusion accuracy curve is in accordance with the final device.
NOTE

Infusion accuracy may be influenced by the pump's environment (such as
pressure, temperature, humidity and any infusion consumables used).
