Best advice I can give is don't mess with it too much. Needs to stabilize. I know it's hard if never hatched before.
By the way, I have the same Ovation Adv and just set it up to test for the first time. When you get to the Humidity Setting, it says right on the display "EX Only" so you can disregard thus setting as I suggested earlier. Remember also, as others have said, it's surface area of moisture element that controls humidity. Not the depth of water in the well.
