START UP GRAPHS AND TRUMPET CURVES
Chapter 7
The graphs show the accuracy/uniformity of flow in relation to time. They allow
for the following:
The delivery behaviour or delivery precision is essentially influenced by the type
of the disposable used. Deviations from the technical data of the pump cannot be
excluded if lines (disposables) other than those stated in the order data are used.
