摘　　要：此文按照《自动气象站检定规程》介绍的用超级终端对PTB220气压传感器进行数字量调整的方法,选取一台CAWS型自动站气压传感器进行实时调整,通过实验,解决了RS-232串口通信电缆的具体制作方法及《自动气象站检定规程》中没有提到的多点调整时检定结果修正值和初始修正值的叠加问题,从这两个方面对规程中关于PTB220气压传感器的调整进行了补充,使超差的气压传感器误差恢复到允许范围之内,为自动站超差气压传感器的调整提供参考。The method of digital adjustment on PTB220 barometric pressure sensor with super terminal is introduced in ＇Verification Regulation of Automatic Weather Station＇. According to this method, this paper chooses one CAWS barometric pressure sensor for real-time adjustment. Though experiment, fabrication of serial-port communication cable are specified , and the overlap problem of corrected value and initially corrected value which occurs in multiple-point adjustment are solved. These two aspects can make sensor error restore to the extent of permission and provide applied reference for adjustment of super-different barometric pressure sensor of AWS.
