Hi. I have two LPS25HB on PCB board. After I cooling them with room air, they show signifacant drop in pressure readings. Do they have full temperature compensation? Are compensation registers protected from accidental erasure?

I thought so too. Then what is this drops on the pressure graph?

If you're blowing on them, that will affect the pressure ...

I only blow on them for about 10 seconds. After this, they restore pressure within 400 seconds.
