I just got a new refrac and the instructions are a bit confusing. It tells me that the ambient room temperature for proper calibration is 68F. Is that correct? It also says that shifts in ambient room temperature will require recalibration for accurate readings..? I don't understand that part. I'm not going to be using it at 68F, so there will be a shift. Help please! TIA.
