Norman, I've left my digital hygrometer in a small sandwich bag with dampened salt (using distilled water) for 48 hrs (I have lots of patience) for an initial reading. Then, have opened the bag to give the calibration knob a click or two, up or down, for adjustment, close the sandwich bag and monitor for 24 to 36hrs. I just like to make sure
