| Abstract: | This paper puts forward a calibration system of electronic pressure meter with 98 microcomputer. In order to complete the accurate measurement of frequency,the HSI timer function of 98 microcomputer is developed.To meet cut off power source and data transmisslon,HSO output and RS 232 communication of 98 microcomputer is exploited. In addition,the program flow diagram about 98 microcomputer is given in detail. Practical use shows that the signal interface composed of 98 microcomputer is simple in structure and with that of reliable functions and wide applicatlons,thus is an ideal measurement device of the ca1ibration interface of high accurate electronic pressure meter. It is practicable that 98 micromcomputer is used in a calibration system of e1ectronic pressure meter. |
