4 Automatic pressure measurement and 20 ? value conversion are completed, thus dynamic automatic compensation between pressure and temperature is completed. It also shows the pressure under the measured ambient temperature,the pressure under the ambient temperature at 20 ? and the ambient temperature. The problem of field calibration of SF6 gas density relay is solved thoroughly.
