    Most people look at taking field measurements the same way they do painting. Although anyone can paint it takes time and experience to actually qualify as a painter. The same is with field measurements except there is a lot more to it and it takes a lot more time to be good at it than most think. The first thing you have to learn is what measurements do you need and what instrument will give the results you need and how to use the instrument. It takes about 5 years to learn test and balance well enough to handle most situations encountered. Although the fan laws are great you have to learn the difference between the theoretical and reliance on actual measured values.
