In order to improve reading method and upgrade intelligence,a design!of automatic reading system for verification of liquid-in-glass is introduced in this paper.

This article discusses in detail quick adjustment methods and accurate reading of dividing light meter with whole experiment operator process and experiment data treatment case.

This paper through the analysis of electric power meter measurement principle,connection mode and method of reading,introduced low power factor in the use of the ctric power watch should pay attention to the problem in detail.

Common errors and solutions in dealing with the readings of the spectrometer;

It also analysed and sumed up the reading errors made by incorret methods of people;the titration’s errors and configuration solution s errors made by the readings errors.
