I am a somewhat newbie with the 5 in 1 unit. My problem is the barometric pressure.
Local airport: 29.82 - has been steady for 5 hours
Display: 29.64
MyAcuRite: 29.86
WUnderground: 29.87
As you can see the display is way off. How do I fix it?
I also read something about the barometric pressure having a "14 learning period" should I do something now or later?
Let the display adjust for the 14 day learning period. By then it should be close to a sea-level adjusted pressure.
It will continue to adjust for another couple of weeks after that.
Depending on the model you have, you can also make a manual adjustment. However, it's best to wait until the learning period is complete, otherwise you'll just be chasing your tail.
Remember the learning period only affects what is shown on the display. It won't be transmitted anywhere, even if your display has a USB port.
