Digi Hygrometer

Question regarding re-seasoning: Will I need to do anything to recalibrate my digital hygrometer? Or while my humi is re-seasoning will it essentially do this itself based on how much moisture is in the air?

The reason I ask is because its been a good two to three years since I seasoned my humi when I bought it. If I'm going to start buying Stogies again, I obviously want to re-season it.

Thanks guys
