Forgive me if this is a silly question but I've never used a refractometer, considering buying one after hearing bad things about the swingarm I have now.
The scale on that says 20 degrees Celsius, but the text notes automatic temperature compensation. Can you say how this works? Do you have to refer to a conversion chart or something or ???
