Barometer indicator
Reference to changing air pressure at the
same
site
enables weather forecasts to be made. If the
air pressure rises, the weather can be expected
to improve; if the air pressure falls, the weather is
worsening.
If the chart is rising from left to right, the air
pressure has risen and the weather can be
expected to improve.
If the chart is falling, the weather can be ex-
pected to deteriorate.
If the chart remains stable, the weather is con-
stant.
The bar chart in the main barometer menu
displays the air pressure trend for the past
4 hours and therefore enables a weather forecast
to be made. The chart compares the air pressure
values measured 4, 3, 2 and 1 hour previously
with the present value. One bar height is equiva-
lent to 3 hPa (3 mbar).
If the difference over a 4 hour period is greater
than 7hPa, the segments which extend beyond
the range of 6hPa begin to flash. This is a clear
indication that the air pressure is changing fast. If
this happens with falling air pressure, a severe
weather deterioration or even a storm, must be
expected.
Barometer display reset
Press the Victorinox emblem for
4
seconds to
reset the display.
If the difference between two measured values is
too great, the barometer is automatically reset.
This is equivalent to an altitude difference of
50 m within thirty minutes. The assumption is
that the position rather than the weather has
changed.
Significance of the arrow
The arrow shows the barometer trend. If the
arrow points upwards, the air pressure is tending
to rise. If the arrow points downwards, the air
pressure is tending to fall. The arrow shows
whether the air pressure change is persistent. If
the change is only a fluctuation, the arrow does
not appear.
