The Altimeter Page
You can customize the ‘“View” option displays using the ”Zoom
Ranges” option to determine time, distance, pressure, and elevation
parameters. If you know the correct elevation for your location, you can
increase the accuracy of the altimeter using the “Calibrate Altimeter”
option. Use the “Reset” option to clear recorded data from the page and to
begin recording new data.
Plot Over Time/Distance
These two measurement options (changes over a set period of time
or changes over a set distance) apply only to the “View Elevation Plot”
option, while the “View Pressure Plot” option is measured by time and
pressure only. When one option is active, the other is displayed on the
Page Options Menu.
View Pressure/Elevation Plots
When selecting the “View Elevation Plot” option you can plot a profi le
of elevation changes that occur as you navigate over a set distance or
period of time. When you select “View Pressure Plot” you can view a
record of changes in barometric pressure for a set period of time. When
one option is active, the other option displays on the Page Options Menu.

Options Menu and then press in to display the plot.
2. Adjust time and distance measurement as desired using the
