Jim,

I've been using Tramex meters for years and one thing that I've learned is that the meters can mislead you. If you're getting the same readings throughout and you don't have water/moisture problems in a basement or crawl then I have to think the meter should be ignored. Having high readings all over is exceptionally unusual and worth doubting.

I always use the meter on a relative basis. If I have moisture readings in the ceramic floor away from the toilet I notch the sensitivity down and try it again. Unless I can get the meter to give me a low reading somewhere I am not going to put much faith into what it's telling me.
