When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch will use that value to convert
the current barometric pressure reading to altitude.
• When mountain climbing, you can specify a
reference value in accordance with a marker
along the way or altitude information from a
map. After that, altitude readings produced
by the watch will be more accurate than they
would without a reference altitude.
Displaying Your Current Altitude
You can use the procedure described in this section to display your current
altitude. If you leave the watch in the Altimeter Mode, it will update the
displayed altitude value regularly, and indicate reading-to-reading changes in
a window in the upper left of the display (page E-38).
You can select either of the following two altitude measurement intervals.
0'05": Readings at five-second intervals for one hour
2'00": Readings at five-second intervals for the first three minutes followed
by two-minute intervals for 10 hours
