Practical Measurement Uncertainty - Calibration

Course ID PMU
Format Classroom

Review and calculate specific examples for measurement uncertainty. This course teaches a practical approach to measurement uncertainty applications. Examples are relevant whether you are a testing laboratory or calibrating in the electrical, physical/dimensional, or inspection areas.

Learn a practical approach to measurement uncertainty applications. Focus on measurement uncertainty for calibration laboratories. Understand the steps required, accepted practices, and the types of uncertainties that need to be considered by accredited laboratories.
