Need help, I have a dual scale refractometer, and I read an article online that claims that I shouldn't read the SG side, only the Brix side. so I went in and converted all my SGs to Brix based on a photo I took inside my refractometer. My efficiencies went through the roof. the model I have is RSG-32ATC, and here's a picture of the inside ... Should I be reading the Plato Brix side? Or the SG side?
