There are many differences due to the different classification category of value measurement method in the measurement process of pressure interface pressure checking instrument. Use different methods may lead to the final measurement conclusion there are differences. In order to better determine the different measurement methods on the result of measurement, for a certain pressure interface pressure checking instrument for different methods of measurement. Through the analysis of measurement results, found the sample measurement of performance at the same time deepening the understanding of measurement. Measurement work and the use of measuring instruments must be closely integrated. Ensure the dissemination of accurate and reliable.
