I bought brand new AIM meter from Solid Signal (updated to latest 4.2) and was able to align the dish, I was able to perform most of the test but one the IN LINE TEST to see how much power I am getting at different points in my system. I was connecting AIM meter in series with line. eg. If I wanted to perform Line test from ODU to POlarity Locker I connect my aim meter odu f connector to cable coming from ODU and IRD F connected to cable going to Polarity Locker. It does not show any voltage or anything every thing is 0 Is my Meter not working properly? or I am making any mistake.
