SpletHow A 4-wire Kelvin Test Identifies Concealed PCB Warriors. A 4-wire Kelvin test always locates the milliohm resistance variations from hole to hole. It also leads to a more complex separation of a pass from failure. Typically, you'd need to measure a few boards or panels to know the running average on the resistance measurements. http://www.jihzx.com/en/jiage.html?id=176327
