http://ift.tt/2h3t0Gy I worked in the field while in college, but then we were really limited to cans and alphas? From my recollection, various things can change readings from minute to minute, but this test was in a closed, empty house and the weather was pretty constant the entire time (last weekend in CO). Anyone ever see this much change in a known secure location? Why would this it roll down to 1/6th and start to go back up?original post: http://ift.tt/2zxnjHE via /r/DIY http://ift.tt/2z2yA6P
