Information about theatmospheric pressure
The weather station can display theatmospheric pressure in different ways,
ABS absolute (actual pressure at current altitude) and REL relative (what thepressure
would be at sea level).
• The relative value is used by meteorologists to be able to compare
theatmospheric pressure at different locations.
• The normal atmospheric pressure at sea level varies depending on
thegeographical location but is usually approximately1013.2hPa.
Apressure of under 990 hPa is regarded as low pressure and over
1020 hPa is regarded as high pressure.
• Since atmospheric pressure decreases with altitude, values for relative
atmospheric pressures are generally higher than their absolute counterparts.
Sound settings for buttons and alarms
In normal mode, hold in [HISTORY/-] for 3 seconds to switch thesound on/off.
BUZZON (On) or BUZZOFF (Off) will appear on thedisplay respectively.
When thesound is switched off, no noise will be heard when buttons are pressed
and any alarms emitted by theweather station will be silent (only thealarm symbols
will flash).
