Development of full automatic calibration system for process calibrators

The article has developed a full automatic calibration system for process calibrators which can be program-controlled. This article describes the composition of the system, the design of the hardware and the structure of the software. The system has overcome the difficulty of automatic wiring-switch during the calibration, and then it can complete full an automatic calibration for various models of process calibrator without human aids. An experiment has verified that the calibration with the system can meet the requirements of current calibration capability, and has a 30% higher efficiency than that with traditional manual method.
