WebA long-standing rule of thumb in the calibration industry prescribes a 4 to 1 test uncertainty ratio (TUR) between the DUT accuracy and the reference standard accuracy. So, for instance, a 100 psi pressure transducer with an accuracy of 0.04% full scale (FS) would have to employ a reference standard with an accuracy of 0.01% FS for that range. WebTo calibrate a Bourdon type pressure gage and to establish the calibration curve of Bourdon Gage. Also determine the gage errors. 1. Apparatus: i. Dead Weight Calibrator. ii.
