6.6 BAROMETER:
The barometer shows the actual air pressure value. This value may be indicated as an absolute or relative
value.
Relative air pressure:
The air pressure varies depending on the altitude (compared to sea level).
The absolute air pressure is the air pressure that is present independent from this altitude (take this value
as reference). For the prediction of the weather, it's essential to measure the correct air pressure, also when
you're e.g. 100 meters above sea level. This is called the relative air pressure. For every 8 meters, the air
pressure decreases by 1 hPa. When you're not located in the mountains, you don't have to adjust the air
pressure.
Press the "WEATHER-ABS REL" (35) button at the rear to switch the display between Absolute and
Relative.
Adjustment of the weather forecast icons and the relative air pressure indication.
• press and hold the "WEATHER-ABS REL" (35) button until the weather station emits a beep tone and
the weather forecast icon starts flashing.
use the ▼ and ▲ buttons to select the actual weather condition.
•
briefly press the "WEATHER-ABS REL" (35) button again.
•
the air pressure value now starts flashing.
•
you may now use the ▼ and ▲ buttons to adjust the relative air pressure.
•
• the air pressure value can only be adjusted in the relative air pressure mode.
• press the "WEATHER-ABS REL" (35) button again to save your setting.
Trend indication:
The air pressure is higher compared to before
The air pressure remains the same as before
The air pressure is lower compared to before
