WTF happened to my hygrometer?

That button is to calibrate it to 75%, not to reset. It sounds like yours is off about 10% which would make your RH a very comfy 64%.

Do the salt test and re-calibrate... if you havent changed your battery in a while, now would be a good time too, so you dont have to re-recalibrate.

OH okay. Didn't know the button put it back at 75%. I guess I'll have to salt test the bugger again. Thanks for the help guys
