Hi guys, this question is for people with standalone systems. What kpa reading are you guys getting with the engine off. I'm getting ~87kpa's that seems a little low but we are up ~3600 ft....?
EDIT: after a bit of searching I have found this chart
http://www.sablesys.com/baro-altitude.html
Now if you look at the far right for 3500 ft it's 89.15 kPa So I guess my sensor isn't off by much if any. I'd still like to get verification from others tho.
And on a side note, does anyone know the difference between barometric and altitude pressure? because if you look at the weather network our pressure here is actually higher then vancouvers right now 101.91 vs 101.51 they must use some sort of correction that takes out the altitude and just goes by the small pressure changes created by the weather?
