Does anyone know the differences between the older PAT4 DV and the newer PAT4 DV/3.
I read in a 2003 article somewhere that there were changes to the tests done in the newer model to conform with newer regs. Is this true?
I am considering buying the older model but am wondering if I am wasting my money. Would it seriously affect the way PAT tests are done.
