Calibration and correction of temperature:
It must revise Zero before measure.First,take few drops of distilled water,put it on the detection prism,and then screw the bolt of Zero so that make it reach 0%,Second,clean the detection prism to inspection.Some models of instruments have to take place standard liquids of distilled water to revise.
