[wxqc] Vantage Pro Barometer problems

[webmaster]

Hello again,

Awhile ago I brought up the issue of barometer error and a local 
person who has been around long enough to have a 3-digit CWOP number 
said the barometer problem with the Vantage Pro is a known issue and 
he had to "lie" regarding his altitude to get proper readings.  Here 
is what he said:

"It looks like you have a Vantage Pro. Your pressure was good at 1016 
millibars and fell more
rapidly then KLVN. The solution is to lower your Altitude. Example: I 
am a 1288 feet. I had to
lower my altitude in the console to 450 feet then adjust the offset 
to the correct pressure. This
compensated for inaccuracies in the barometric pressure sensor. Now 
it tracks dead on. Try 450
feet and see how it tracks. Adjust your altitude up if its not 
changing enough or down if its
changing to much. It took me a while to figure this out but it works. "

Has anyone else heard of this?  If I have to "lie" to get proper 
readings, I am OK with that.  I wrote Davis about the issue and they 
never replied.

Thanks,

Lew
