The invention relates to an intelligent instrument definite value setting method and an intelligent instrument. All definite values are subjected to modular processing to obtain modular data blocks, then the data blocks are imported into the intelligent instrument at a time, and the intelligent instrument parses the data blocks to obtain corresponding definite value data. Thus, the definite valuesonly need to be processed once, and then only the data blocks obtained after processing need to be imported into the intelligent instrument each time the definite values are set. There is no need toset or sequentially input the definite values one by one, the workload is reduced greatly, and the processing process is simple. The obtained data blocks can also be saved as electronic backups, so that when the intelligent instrument is damaged and internal data is correspondingly broken, data of the definite values are unlikely to be lost, and the preservation effect of the method is better thanthat of paper. Moreover, after maintenance of the intelligent instrument is completed, the data blocks are directly imported into the intelligent instrument again, and there is no need to sequentially input the data blocks one by one.
