DIY Weights and Measures: Developing your own calibration methods using available materials

  • 1. Bioproducts and Biosystems Engineering Department, University of Minnesota


In most cases, when a custom device is built, when an instrument arrives from the manufacturer, or when a piece of equipment is picked up from the store, it is assumed that it will just work, and that data from it will be completely reliable. This fundamental expectation by many scientists is completely unfounded. Between shipping, variable environmental conditions, and many other factors, sensing systems and instruments will be out of tolerance when used. In order to get them back in tolerance, or to at least find out what their uncertainties are, characterization is necessary. If adjustment to the device is possible, this is carried out and called a calibration. In this work, several ways of generating characterization and adjustment methods are discussed, with acoustic, hydraulic, and meteorological devices as examples.
