Plot
to view a record of changes in barometric
pressure for a set period of time. When one option
is active, the other option is shown on the Options
Menu.
Zoom Ranges
You can set the zoom ranges for elevation, distance,
or time when you show the View Elevation Plot.
• Ranges for vertical distance are shown as you
press up or down on the
ROCKER
.
• Ranges for linear distance are shown as you
press left or right on the
ROCKER
.
• Ranges for time are shown for a time plot when
you press left or right on the
ROCKER
.
Ranges for View Pressure Plot pressure values are
shown when you press up or down on the
ROCKER
.
Values for time are shown in the same manner as for
elevation plots.
View Points
You can scroll through a recorded elevation or
pressure profile to view data for any point along the
profile. When the red vertical and horizontal cross
hairs are stopped at a location along the profile, the
screen shows the elevation or pressure, time of day,
and date when the point was recorded.
View Points on Map
You can view the location of points on the Map Page.
Resetting Data
You can reset the elevation data and the maximum
elevation data by selecting these options from the
Reset Page.
Calibrating the Altimeter
Because the Receiver relies on the barometric
pressure to determine the elevation and the pressure
at any given elevation can fluctuate, you can calibrate
the altimeter to increase its accuracy. You must know
the elevation or pressure at your current location.
Changing the Data Fields
The Altimeter Page has two data fields that you can
customize. (For definitions, see page 84.)
