| Abstract: | In this paper. how to improve the sampling accuracy of sensor in the computer measure and control system was discussed. Sample the zero data to prevent temperature excursion before each test. Non-linear problem is resolved through subsection linearizations. if the segment is short enough, the accuracy of result will be greatly improved. According to the samples the calibration methods and the sampling procedure were studied. |
