The quality of pressure gauge calibration work largely depends on the professional quality and skill level of calibration personnel. Calibration personnel first need to have a solid foundation of metrology knowledge, including pressure measurement principles, error theory, value traceability systems, etc., in order to deeply understand the essence and requirements of pressure gauge calibration. In terms of practical operation skills, they should be proficient in using various calibration equipment, from precision pressure generators to digital pressure gauges, and be able to accurately connect equipment, set parameters and read data. At the same time, calibration personnel should also have good data analysis and processing capabilities, be able to use statistical methods to analyze calibration data, judge the performance of pressure gauges and formulate reasonable correction plans. In addition, with the continuous development of technology, calibration personnel need to continuously learn new calibration technologies and standard specifications, participate in professional training and technical exchange activities, such as training on new intelligent pressure gauge calibration technologies, international and domestic calibration standard seminars, etc., to continuously improve their professional quality and skill level, adapt to the increasingly high requirements in the field of pressure gauge calibration and lay a solid talent foundation for providing high-quality calibration services.
