Got my Doser 2 about 2 weeks ago and after fumbling to get it to work (was using an Android tablet app) It has the current firmware and was set up through a PC (found a fellow reefer gracious enough to bring his lap top over). My household is apple exclusive except for the new tablet I bought to use the android app with for this doser.
Here is my issue, the doser is not dosing the correct amount even though I have repeatedly recalibrated the pumps. So I thought the firmware update might help so this is now complete. But after the update, the dose amount is not matching what is programmed in the app. I have re-calibrated each pump 4 times since the firmware update and saved the changes. Waited 5 minutes for the changes to save, loaded the changes, bled the lines to remove any air bubbles, set up dedicated containers to receive the dosed mounts. The dosed amounts are off (less) by 15 – 30% than what is programed. Example, pump one is programmed to deliver 4.2 ml 9 times a day. Pump is calibrated at 41 ml per minute and that is saved and loaded but each doe it dispensed is 3.5 ml.
If I change the flow rate from 41 ml per minute to 33 ml, the amount dosed is pretty close to 4.2 ml. This is just pump 1 and I have similar results for ALL pumps, this shouldn't work like this right? Any ideas or could I have a bad unit? This unit has never dosed the programmed amount,
