Fig. : Flow Diagram Membrane Movement to Inlet Side
The FPA pump is driven with 1500 ml/min and moves the membrane to the
inlet side. Thus an overpressure is built up at the valves VABK1/2 for the next
test step. If the membrane is not in end position: Only the pressure of the
throttle DDE is built-up prior to the valves, due to the volume shift.
