Probably not, it only takes a few minutes for a hygrometer to adjust to the humidity. When I open my refrigerdor, the hygro is mounted on the door so if I keep the door open and the room is dry, it adjusts itself in less than a minute to the RH in the room (I have a hygrometer on the wall in the room too).

I really don't know what to tell you other than to not worry too much about it. RH varies slightly (unless you're using beads) and I pretty much only worry when I see a huge move down which means ADD MORE WATER.
