Calibrated my Pressure Sensor

The pressure sensor at UKBKB Spanish Fork (aka EW2355 Spanish Fork), has read wrong since I installed the weather station several years ago. I finally borrowed a Kestrel 4500 from work to apply a correction to my pressure sensor. As a result, I reduced the pressure reading on my Davis Vantage Pro 2 by 4 hPa.

You can see the change in the MesoWest time series plot when pressure decreased 400 Pascals:
