Most of the theory is pretty basic and given in the video lecture. The object of the test is to plot the deadweight pressures (reference) against those reported by the gauges. The theory behind that is given in the monograph Least Squares Analysis and Curve Fitting.

- Fluid Power Systems: An Overview and Design Example
- An Overview of Tapered Pipe Threads, and Their Application at Vulcan, which is how the gauges are held to the pressure gauge tester.
