How big is the humidor? Kinda goes with the 2nd question.
What kind and how much beads do you have in it? As much or a little under effects the RH by a few points as I've noticed
How full is it? Near empty will lower the RH
Did you give it a few days or a week to settle down? Usually after a day or two I see an RH jump a few points
All of the above are why my humidors didn't read correctly on their hygros. Everything is peachy now though
