Course overview

Calibration is more than simply checking or adjusting an instrument.  Calibration involves ensuring the gauge under test is working properly, ensuring the reference instrument has a traceable calibration, comparing the two instruments using an appropriate method, and calculating the measurement uncertainty.

The workshop teaches attendees an efficient method to calibrate pressure gauges that meets the technical, quality and legal aspects of calibration.  A feature of the method is the straight forward way that the measurement uncertainty is calculated.

The presentation includes many demonstrations and hands-on activities that will be of interest to new and experienced users.  By the end of the day, attendees should be able to calibrate a pressure gauge, calculate the associated measurement uncertainty, as well as carry out regular in-service checks on refence equipment.

Programme Outline

Topics include:

- Selecting pressure measurement equipment
- Use and maintenance of deadweight testers and reference gauges, including carrying out in-service checks 
- Understanding deadweight tester calibration certificates
- Methods of pressure gauge calibration using either deadweight testers or reference gauges 
- Calculating measurement uncertainty
- Meeting ISO17025 or in-house quality requirements for traceability

The material in this course is based on MSL Technical Guide TG13 (Pressure gauge calibration), TG16 (Care and use of a deadweight tester) and TG36 (Calculating deadweight tester pressures).

Presenter Profile

Darrin Jack has worked as a pressure metrologist for more than 12 years. His work has involved him in a wide variety of measurements including calibrations of high-accuracy barometers, gas and oil deadweight testers, as well as a wide range of manometers and transducers. His current research area is the automation of barometer calibrations.

Mark Clarkson has worked as a metrologist for more than 20 years in the areas of mass, force, density, pressure and optical measurement. During this time has also been a technical assessor for IANZ assessments of Metrology and Calibration laboratories. He has developed and presented over 45 training workshops in mass and density measurement and uncertainty calculation for testing laboratories. Mark's research interests include development of a non-artefact standard utilising a pressure balance, and he is also a guest lecturer at Victoria University of Wellington.
