A Measurement Uncertainty Introduction The program combines individual measurement uncertainties to arrive at total uncertainty, and that establishes a range of ambiguous results and a boundary beyond which results are de nitely unacceptable. Total uncertainty multiplied by a measurement uncertainty coe cient combines with speci cation limits to determine the test limits, which determine acceptable system performance.
Combining Individual Uncertainties Individual measurement uncertainties vary with test equipment and measurement techniques. Either of two methods of combining uncertainties produces a total uncertainties gure: Worst-Case Sum, or Root Sum of the Squares (RSS). Worst-Case Sum de nes boundaries of total uncertainty without providing a speci c estimate. RSS is an accurate and statistically signi cant estimate. Where appropriate, the tests use RSS.
Combining Uncertainty and Specification Using the instructions in this section, a quali ed person can change the measurement uncertainty coe cient on a test-by-test basis. On Test Disk 1 there is an ASCII le named TEST LIST, which contains a section for every test applicable to the particular system software package. (Use GET and SAVE to retrieve and store ASCII les.) Each section has a line labeled FLAGS; in other words, there is a FLAGS line for every test.
