I am having many problems with my acurite digital hygrometer/thermometer. It is saying that the humidity inside the incubator is less than the shelf that it is sitting in. I have two and neither one seemed to be right after each one was in the incubator over a day. I don't have the red plugs in my incubator (its a hova-bator). It is a circulated air incubator, it is saying that it is only 47% humidity in the incubator, but it says that the humidity has gone all the way up to 99% is this thing broken or what? I have eggs going into the incubator today...Do you think I need to get a new one? It worked fine the last time I incubated eggs.
