Abstract:According to the performance specification requirements of the R97 International Recommendation and Verification Regulation for JJG 875-94 Digital Pressure Gauge for vibrating barometers, a complete performance test was conducted on vibrating barometers (model DQZ-1), which are widely used in conventional weather stations and aviation departments and other fields. The static performance test (repeatability, nonlinearity and hysteresis), thermal test, humidity test, short term stability test and long term stability test are described. The main factors causing measurement errors were identified through the study and analysis of experiment data. They are very useful for improving the accuracy of atmospheric pressure measurement.
