Ambient Weather and Ecowitt and other Fine Offset clones / Re: Will the real pressure please stand up?
« Last post by Ahill on Today at 12:33:49 PM »The Davis VP2 has very different firmware. All you have to do is enter in your elevation and you are done.I believe your console will automatically calculate Altimeter.
Your Davis system has the better, more accurate algorithm, so it should be preferred over the Ambient station.
Don't upload both weather stations to CWOP - just use the Davis.
I have been noticing that with the quality check on cwop the ambient station has been averaging about .45mb( half a mb ) high to madis. When it gets to 1mb or more difference it needs to be recalibrated.
The davis which supposedly has a better more accurate algorithm is even higher than the ambient average by about another .4 mb after just entering the elevation.
If i don’t calibrate the davis it would then be about 1mb higher than the madis and out of recommended range.
So at this point does the davis need to be calibrated using the same method as did for the ambient or should I just adjust the difference on the davis using the ambient?
