      1 inch Hg = 33.85 mbar.  The value that's read from the station is in millibars (hPa) regardless of the display setting.  I can't speak for the accuracy of the station itself, but if you set the display to relative mode and hPa, it should agree with the raw value reported on the air.

      Hi Scott,

      I calibrated the 2317 a couple of days ago using the data from the
      nearby airport. I just checked the airport agianst what the 2317 is
      displaying and they are within .02 inches of HG of each other.

      The console displays in inches of HG and FindU reports in millibars.
      Do you happen to know what the conversion factor is between the two?
      Is the conversion to millibars done in the T2?

      I just noticed that I was displaying absolute pressure on the
      console. I just changed it over to display relative pressure. I
      doubt if that would make a difference on what is sent over the serial
      port.

      I'll also see if I can manually check the 2317 against the Peet over
      the period of the next day or so. I'll start by recalibrating both to
      the airport and each other and see what happens.

      Mark
