I have recently switched to the DOS/DDR set up for dosing, set up everything according to the manual, and assumed things were fine, as it calibrated fine, pulled fluid through the tubing and it showed in fusion the DDR was dispensing fluid. As it turns out, nothing was actually being pushed out (even though fusion was accounting for the missing fluid through the sensors). It seems it is not pulling the fluid through the hard plastic inside the DDR, but if I put the tubing directly into the resevoir, it works just fine.
1. Has anyone else had issues like this?
2. Is there something I can check/do to fix this? (I would hate to think I can't actually use the product as it was designed)
Thanks in advance for the help/feedback.
