My first question is what should you do for calibration if you don't have a hydrometer that you can rely on? Part of the reason I got a refractometer was because I didn't think my hydrometer was accurate and I was very frustrated in trying to test it with 60 degree water (too warm, no too cold, no too warm again). So if your hydrometer isn't accurate or you don't have one, what should you do?
More importantly I'm not sure I understand the purpose of this tool. I have readings for pre fermentation and pre bottle but I'm not seeing what I expect. If I select "unfermented" and enter my value I get a SG that I think is correct. I then switch to "finished" and try to enter that value but the results are very strange. Clearly I'm not using this as expected but I can't figure out what you're supposed to do. I just want to use my brix settings to find the translated gravity readings and ABV.
