When taking superheat on a cap tube system, reach-in, or prep table with a cap tube. Where is the proper place to measure suction line temperature. I have seen guys measure it 3 inches away from the compressor on the suction line. This is taking compressor superheat or total system superheat I am assuming. But where is the proper place to take temperature on the suction line on small self contained systems with a cap tube to verify proper performance. Some clarification would be greatly appreciated.
