Altitude display
On the top line:
Graph of variations in altitude over the last six hours. One dash
corresponds to a time period of 15 minutes. The range of the graph is
calculated according to the variations in maximum altitude. You cannot
therefore read the altitude value from the graph.
On the middle line:
In the middle, the altitude at the measurement site is displayed. The
unit of measurement (m or ft) is indicated at the bottom right of the
figure.
On the bottom line:
Local time display.
To change the units of altitude measurement (m/ft)
Hold
down B until the unit symbol (m or ft) stops flashing to set the display to
the corresponding unit.
Display maximum altitude and positive altitude difference
The watch stores the maximum altitude and the positive altitude
difference measured throughout the time spent in Altimeter mode.
I
WARNING:
these values are not updated when the watch is in a
mode other than “altimeter” mode.
I
WARNING:
the watch does not calculate negative altitude difference.
•
Calculating positive altitude difference: the watch takes the sum of
all positive vertical movements (climbs) made during the
measurement period. E.g. if a hiker climbs 10 metres, descends 5
metres and then climbs a further 10 metres, the positive altitude
difference is 20m.
I
WARNING:
The calculation of cumulative altitude difference is a
mathematical one. If the display oscillates between two values, the
cumulative value will increase every time it oscillates between the
lowest and the highest value. The cumulative value will therefore be
more accurate when climbing regularly than when travelling at an
altitude which is more or less constant.
