I know this is a VERY old post but I'm using a new Rapt Pill for the first time and got similar results. Standard calibration done with tapwater seemed to work fine. OG on the hydrometer was 1.048 but when the Rapt Pill reading came back it was at 1.090. 4 days in and it is now at 1.059 (this is a fast acting yeast). Do I just take the drop in gravity and apply that to my OG hydrometer reading? Did you ever get the pill calibrated to report the correct SG?So I did the standard calibration in tapwater at 20C before firing it into the fermenter on Saturday. I had read 1.068 with a hydrometer (dead on beersmith target, so apparently my profile works) but the pill was reading like 1.093. I pitched kveik Voss so it fermented pretty quickly and the lower gravity readings seem to line up better, which makes sense given the calibration point is at 1.000. watching that curve drop hour after hour is pretty great, even if the absolute values are a bit off!
I've read a couple of other posts about people having similar issues with accuracy but I'm not sure if there's a silver bullet fix. Did anyone try the advanced calibration? Any chance I managed to assemble the thing backwards?
Thanks,
David
