voltage. A value greater than 3.2V is required for a 'GO'

=== Save Flight Data
The altimeter records flight data to its internal
- flash memory. TeleMetrum data is recorded at a much
+ flash memory.
+ ifdef::radio[]
+ Data logged on board is recorded at a much
higher rate than the telemetry system can handle, and
is not subject to radio drop-outs. As such, it
provides a more complete and precise record of the
- flight. The 'Save Flight Data' button allows you to
+ flight.
+ endif::radio[]
+ The 'Save Flight Data' button allows you to
read the flash memory and write it to disk.
Clicking on the 'Save Flight Data' button brings up a
list of connected flight computers and TeleDongle
devices. If you select a flight computer, the flight
- data will be downloaded from that device directly. If
- you select a TeleDongle device, flight data will be

downloaded from a flight computer over radio link via
the specified TeleDongle. See
<<_controlling_an_altimeter_over_the_radio_link>> for
more information.

After the device has been selected, a dialog showing
the flight data saved in the device will be shown

=== Graph Data

This selects which graph elements to show, and, at the

+ very bottom. It also lets you configure how
+ the graph is drawn:
+
+ * Whether to use metric or imperial units
+
+ * Whether to show a marker at each data
+ point. When displaying a small section of
+ the graph, these can be useful to know what
+ data values were recorded.
+
+ * How wide to draw the lines in the graph
+
+ * How to filter speed and acceleration data
+ computed from barometric data. Flight
+ computers with accelerometers never display
+ computed acceleration data, and only use
+ barometric data to compute speed during
+ descent. Flight computers without
+ accelerometers always compute both speed and
+ acceleration from barometric data. A larger
+ value smooths the data more.

link rate from the transmitter. If they don't
match, the device won't receive any data.
