Thank You, John Adams

Thanks for the response. I can only display absolute or relative pressure, not both at the same time. Which should I display, which should be set to the sea level station reading and which should be the higher reading once I have applied the 3mb correction for elevation?

I have just installed a personal weather station and connected it online.Among other outputs, it has Relative and Absolute Barometric Pressure and I need advice on how to set these up. These readings are adjustable and both read from the same barometer source. My weather station is 25 metres above sea level and there is a BOM weather station at sea level and less than a kl away. 25 metres needs a correction of 3mb. If the BOM source read 1013mb, what should I set for relative and for absolute and what should I display as the barometer reading over the net? Thank You John Adams
