WTF happened to my hygrometer?

I have at least one that's goofy like that.
Usually when they act that way it's the hygrometer telling me it wants a new battery. I have a round one that just drives me nuts trying to get it right. Sometimes I get lucky and land at 75%, other times I settle for a point off.

I should mention this...
The sensors on these hygrosets have sticky stuff on them. I have no idea why, or what benefit it might be, but when I'm working at making up beads and bags they tend to get loose beads and junk stuck to the sensor.
Whenever anything gets stuck to the sensor they become notoriously inaccurate.
I have an exacto knife I use to reach in through the vent and I knock the junk off and they heal right up.
It might be worth a look if a battery doesn't do the trick.
