Question 6 In the calibration of a caliper, the following table has been created after measuring a standard sample length of L - 16.40 mm. Five repeated measurement results (in mm) are reported as follows: 16.41, 16.43, 16.40, 16.39, 16.62 Fill the blanks (indicated by ...) in the table and write down the final measurement result and corresponding uncertainties. Sample length L = 16.4 mm Input Quantities Estimated Values Probability Distribution Standard Uncertainty Variance 1. Certificate error 2. Resolution error 3. Mechnical error 4. Repeatability 10.4 um 5.0 um 10.0 um Normal Rectangular Rectangular Normal sum= Total measurement uncertainty u = sqrt(sum) Expanded Measurement Uncertainty U = 2*sqrt(sum) Final Result Note: for a rectangular distribution: o=a/ 13
