3. After selecting units of measure, choose OK.
The software saves your choices. All information will be displayed in the units
of measure you selected.
Set Barometer
You configure the barometer by entering the Weather Envoy's current elevation
and current barometric pressure. If you don't know the elevation, there are many
ways to find out. For example, you can try calling the reference desk at your local
library, looking up your town in an almanac, or calling the local airport. In the
USA you can look at a United States Geological Survey topographical map of
your area.
Here are a few on-line resources for finding your elevation:

1. Choose Set Barometer from the Setup menu.
The software opens the Set Barometer dialog
box.
2. Enter the elevation
The elevation is required for the forecast to
work correctly and to report the adjusted
baromtric pressure.
3. Enter the correct sea-level barometeric pres-
sure.
Note: Only enter this if you have a current reading from
a very reliable nearby reference. Do not use the
Sea-level Barometer setting alone to correct your
barometer to sea-level.
For the most accurate barometer readings, enter a "Sea-level Barometer" pres-
sure from a reliable nearby reference. The Weather Envoy uses this value to
calibrate it's own adjusted barometric pressure calculations. The software
saves the change in barometric pressure in the Weather Enovy and in the
WeatherLink station configuration file.
Note: If you set the Sea-Level Barometric pressure to 0, the bar calibration number is
erased. The station will display the pressure reading altered by the station elevation
only.
