Hi All. Yes the syringe is set up with the correct manufacturer. No occlusions as ran the syringe dry. When we started the test the syringe barrel indicated 34mls while the pump itself displayed 33.9ml (VTBI). At end of run the pump displayed (VI)33.9ml but 1.7ml (visully) left in syringe. Another thing that has now come to light, on another pump when set up, the syringe barrel set to 34ml while the pump display's 32.7ml. My eyes are not that bad to miss read nearly 2mls.
