Study on the technical performance test method of digital barometer test box
At present,no one has studied the test method of the technical performance of the digital barometer test box,and a scientific and reasonable technical performance test scheme of digital barometer test box is developed.Including the requirements for the technical indicators of the selected measuring equipment,the requirements for the required environmental conditions and the pressure transmission me-dium,the requirements for the test air circuit connection mode,the design of various technical perform-ance test methods and the verification of the test results and Taking QYJD-10 pneumatic test box with control range(440～1100)hPa as the test object,take 0.01 level digital barometer with measuring range(500～1100)hPa as pressure standard,digital thermometer with measuring range(-60～81)℃ and digital thermometer with maximum allowable error of±0.05 ℃ as temperature standard,the test protocol was test-verified,comprehensive evaluation of the technical performance of the pneumatic test box are in line with the requirements of the verification or calibration instruments,thus to prove that the test scheme is reasonable and feasible,it provides certain technical guidance for the technical performance test of the digital barometer test box.
