CS106 CR1000 barometer sensor - incorrect result


Firecracker Dec 30, 2013 08:20 PM

Hello all,

The barometer reading in inHg is way off.
Local reading at an airport ASOS is 30.10
My station reads 14.77 hourly

Is it the multi or offset? Both locations are 27 ft above sea level.

'CS106 Barometric Pressure Sensor measurement 'BP_inHg'///////////////////////////////////////////////////
If IfTime(59,60,Min) Then PortSet(1,1)
If IfTime(0,60,Min) Then
VoltSe(BP_inHg,1,mV2500,1,1,0,_60Hz,0.240,518.1751)
BP_inHg=BP_inHg*0.02953
PortSet(1,0)
EndIf

I have tried to find an answer and cannot. Any help appreciated.

Regards

Check your Wiring:
Blue(Brown) to 1H
Red to 12V
Green to C1
Black to G
Yellow(white) to Ground
Clear to Ground

Program to provide Sea Level pressure corrected to 27 ft.

I just used ShortCut which comes with Loggernet.

Thanks David! Didn't want to bother you until after the new year - you always come through.
