Auto Calibration:
Automatically calibrates
the altimeter each time the device is
turned on. The device continues to
automatically calibrate the altimeter as
long as the device has GPS signals
acquired.
Barometer Mode: Variable Elevation
allows the barometer to measure changes
in elevation while you are moving.
Fixed Elevation
assumes the device
is stationary at a fixed elevation, so the
barometric pressure should only change
due to weather.
Pressure Trending:
Sets how the device
records pressure data.
Save Always
can be useful when you are watching for
pressure fronts.
Plot Type:
Records elevation changes over
a period of time or distance, records
barometric pressure over a period of time,
or records ambient pressure changes
over a period of time.
Calibrate Altimeter:
Allows you to calibrate
the barometric altimeter if you know the
correct elevation or the correct barometric
pressure. See page 33.
