A correction method can amplify the inspection signals obtained from the detector which can detect the variable by an amplifier in the experiment of material, and convert the signals through A/D and calculate out the measuring value by computer. Thus, the varieties of the detecting device and the measuring range of each detector preset into the computer; meanwhile, the correct parameter of each measuring range of each corresponding device is stored. When measuring, the computer judges the type and the applied measuring range of each detector and then, multiplies the output signals of the detector with the stored correction parameters for correct calculation of the measuring values. |
