| 摘 要： | In this paper, the construction and performance of the microprocessor-based multi-chan-nel digital thermometric instrument together with its deisgn and fabrication are systematicallydescribed. The principle, method and practical softwares for the entire reference-junction com-pensation processing by microcomputer and the linearization of the characteristic ofthermocouples are also exhaustively expounded with a detailed analysis of the error existing inthe thermometric instrument. The practiced result shows that the apparatus is featured with asimple construction, high accuracy and high ability of anti-disturbance. It is proved to be ofpractical value.
