Hey everybody. I just setup my IV. I used a Blenny for the dosing pump because I already have a Launch with an available PH and Conductivity ports. I got everything setup according the Hydros instructions, calibrated the PH and Salinity probes, calibrated the dosing heads, primed all the lines.
I keep getting an error message about 5 minutes into it. When I start the test, it drains the beaker, fills it up, drains it again using the fill doser?, refills it and it just stops. I see the stirrer spinning so I know that works. My log says that it's dosed .2 ml of reagent. When it quits, it's still full of water and doesn't drain until I restart the test. Any ideas of what's happening?

The salinity showing 0 ppt does not seem right. There is two hidden inputs for the realtime reading for the p( and salinity inputs. It would be interesting to see what they are showing. I setup a page for all my testing and set the hidden tiles so they will be visible.I also setup so only the inputs and outputs that deal with testing show up on the page, This includes my static inputs I have setup. Also the reagent pump has to be a pump that has a flow rate at or near 3 ml per minute. The Blenny pumps will not do that.

I'm not sure where to even start troubleshooting what's happening. Any ideas where to start?
I can pick up a Hydros 2ml pump that I can plug into an open receptacle on my Launch to handle the reagent dosing. But, I'm not sure why it would stop mid test and leave a beaker full of water.
