The paper described the hardware and software designs of an Auto Calibration System for SHCAN61 instrumentin the Field Bus. CAN Bus is used for digital transfer between the Fieldbus instruments. RS-232 is used to be transmittedwith PC. The designed system has been realized and solved the auto calibration problem. The experiment proved thatthis system is easier to use, more accurate, more stable and lower cost comparing with the traditional intelligent instrument?scalibration system.
