Vernier caliper uncertainty of measurement results
Switch to fast forward the following results: 122.8r/rain, 122.7r/min, 122,7 r / min, 122.8r/min122.8r/min122.7r/rain123.0r/min, 122.7r/min. = 122.78r/minS == 0.1Or/rain single measurement standard deviation S = \0r/min,[link widoczny dla zalogowanych], 619r/min620r/min62.2r/min621r/min, 62.3r/min. : 62.06r/mins == 0.34r/rain single measurement standard deviation S = u, l, 1 = 0.34r/rain ③ measurement time was as follows: 60s, 60s, 60s, 60.2s, 60.2s, 6O. 3s, 60.1s,[link widoczny dla zalogowanych], 60.2s: 6. . . 88: (a - 7) 2:. . 2 single measurement standard deviation S = U1U1 = 0.12s ④ stirring the pot's diameter dimensional measurement results are as follows: 202.8mm, 2028ram, 2028mm202.6mm202, 6mm2027mm. 202.7mm,[link widoczny dla zalogowanych], 202.8mm72 a: √. . . ~ Single measurement standard deviation S = the l \uncertainty \√ 0.1702 +0.342 = 0.38r/rain ③ Turn the revolution speed measuring time soon combined standard uncertainty \033 +0.12 = 0.12s ④ stirring the pot's diameter size of the combined standard uncertainty = u2 + u21 = ~ / 0.00672 +0.092 = 0.09rr ~ 2.6 ① Uncertainty expanded leaves of revolution fast = k × Ucn = 2 × 0.37 = 0.74r/rain (k = 2) ② blade revolution slow, = k × \③ Turn the revolution speed measuring fast time = k × ud = 2 × 0.12 = 0.24s (k = 2) ④ stirring the pot's diameter U = k × = 2 × 0.09 = 0.18ram (k = 2) 3 summary report measurement uncertainty mortar mixer planetary the four main technical parameters of the expanded uncertainty measurement results were: fast = 0.74r/min revolution a revolution 0.76r/min slow time = 0. 21S size = 0.18mm Author: Jiang Huijing, female. engineers. work unit: Changchun Institute of Metrological Verification Testing.
