Moisture meters.... anyone know anything about them?

I have had a leak in my garage (town house) for 2-3 years now and fighting the builder to fix the problem.... They now have a game plan to get it fixed this week. They brought a moisture meter in (Wagner MMC 220 Extended Range Meter) and said there was "normal" moisture in the wall (4.0-4.8). my question is will the meter only detect moisture in the dry wall? or will it detect it in the insulation as well, below the vapor barrier? There is 2 layers of drywall on the wall they are testing I would say its 1-1.5 inches of drywall.

One a side note we tested some drywall in a spare bedroom and it said 0.0 any help would be great.

I would have them put a small hole in the wall and measure it on the inside at the top and bottom. I don't see how measuring the exterior would do anything unless the drywall was soaked through.

That would be my guess too. Unless you check all the way through the wall you can't tell where the bulk of the moisture is.
