Formal Training

Course Outline

The course includes instruction in the principles of uncertainty analysis following the ISO GUM Method (as per ISO17025 requirements) and hands-on training in the specific analysis problems relevant to the students' workplace. Each student will receive the handbook used for the training, a copy of the presentation in book form, a single user licensed copy of Uncertainty Toolbox™ for Microsoft Excel®, plus numerous tools and documents associated with computing uncertainties.

Uncertainty Analysis - Day 2: Hands-on use of Uncertainty Toolbox™ to Compute Measurement Uncertainty

Recap of First Day Topics Hands-on Uncertainty Analysis Computations Examples based on actual measurements performed at each attendee's workplace Attendee need only describe measurement process, equipment tolerances and calibration certificates helpful but not required. Actual values can be entered into example by student upon returning to workplace.
