I am new to weatherstations, and bought a WH1080. I don't understand how I set up the Barometric Pressure on the instrument. I can select either Relative or Absolute, and I can make the Relative reading be anything that I want when I cycle thru to the third touch of the screen. Why would I want to change a weather condition reading manually? Should I be reading and reporting Relative pressure or Absolute?

You should be reading and reporting relative pressure. This is the pressure corrected for your altitude, and it means that everyone reports values which correlate, regardless of their altitude.

You need to calibrate your barometer by setting your relative pressure to the same reading as a reliable station that isn't too far from you, preferably at a time when the pressure is fairly steady. Once you've done this, your barometer then continues to display the correct relative (sea-level) pressure - within the limits of its accuracy.
