Setting the altimeter
Press the Victorinox emblem for
4
seconds until
the display flashes. Now release the Victorinox
emblem again. You have changed over to the
altimeter setting mode.
The arrow shows the present adjustment direc-
tion. The changeover is automatic.
If the Victorinox emblem is pressed for a longer
period (at least
6
seconds), the adjusting speed
is increased (20 digits/s).
Brief pressure on the Victorinox emblem changes
the display by 1 digit (meter). To increase the
value which is shown, press the Victorinox
emblem repeatedly while the arrow points up-
wards. When the correct altitude is shown on the
display, wait for
10
seconds until the system has
accepted the entry made by you.
The display then changes over to the "Weather
correction mode". When the Victorinox emblem is
pressed briefly, the correction setting can be
altered in the sequence "Stnd", "Cold", "Hot".
Stnd
standard temperature for a particular
altitude (tolerance ±5°C)
Cold
colder than standard (difference greater
than 5°C)
Hot
warmer than standard (difference greater
than 5°C)
(Standard values see table on page 4)
If the button is not pressed within
4
seconds, the
"Weather correction mode" is quit automatically
and the new setting accepted.
Warning!!!
To extend the battery life many times over,
the altitude display has a built-in delay,
therefore, the altimeter must not be used
during sky diving or other similar sports.
Altitude error / Impact of atmospheric pres-
sure fluctuations
A change in the weather causes the barometric
pressure to alter; this in turn means that the
displayed altitude differs from the effective
altitude. The error can be eliminated by adjusting
the altitude. Even on a stable day, temperature-
related air pressure fluctuations of ±1 mbar may
occur; this is equivalent to an altitude error of
±8 meters. Under normal weather variations, an
altitude difference of 40 – 50 m may easily occur
after a single day. If the pressure difference is
great (storm front), a change of up to 100 m is
also realistic. Over a two-day period, a difference
of 200 – 250 m may occur in the event of ex-
treme weather changes.
1 mbar > approx. 8 m
(or approx. 16 m at 5'500 m above sea level)
1 hPa = 1 mbar = 0.001 bar = 0.75 mmHg
Because of these air pressure fluctuations, an
altimeter must always be readjusted before use.
Set the altitude on a daily basis if you are hiking
or climbing or wish to take account of weather
changes. This means that the altimeter must be
reset at a known altitude (e.g. at home, at a
railway station, mountain hut etc.).
