I ain't too smart but you may be on to something there. With the OHMs reading you can find opens in wires or connections or measure the amount of resistance. I know when you hold both probes between thumb and forefinger not touching the harder you squeeze the meter will rise. If it will detect moisture or pass through of it which could be what its doing when between your fingers maybe it would work as a poor mans, Rube Goldberg, I don't trust it, Mickey Mouse, half rectumed moisture meter but like I said I ain't too smart.. See I just put two periods at the end of a sentence and spell check is saying both rectumed and OHMs is misspelled. You may be thinking there is no such word as rectumed but after the accident I heard somebody say "rectumed hell, it killed em" so I know there is such a word.
