Measurement System Assessment II (MSA II)

Non-typical measuremen t systems require more advanced measurement system techniques. This seminar provides participants to the knowledge necessary to perform measurement system assessments for destructive testing, nested systems and other advanced or non-standard situations. It also provides enhanced understanding and utility of core measurement assessment tools taught in MSA I.

Who should attend:
Practitioners involved in the evaluation of measurement systems and any individual making decisions based on data.

Prerequisite:
A knowledge of basic algebra, statistical process control concepts (SPC I) and basic measurement system concepts (MSA I) is strongly recommended.

CEU Credits: 1.6

Duration: 16 Hours (2-day course)
