I just got my new hovabator 1602 and am trying to set the temp/humidity. I have the cheap thermometer that came with the incubator. I purchased a thermometer/hygrometer combo online from incubatorswarehouse.com and have a thermometer that my parents always use (it is one of those meat thermometers, but they have used it in their incubators successfully). They are all three reading different temps. The meat thermometer says 98%, hygrometer/thermometer says 96% and the one that came with it says 92%. Which one do I go by to adjust the temp?
