Setting pressure characteristics at first launch of the unit
1. When connecting the base unit to the net pressure units “hPa/mBar” will
appear on the display.
. Use the ▼/SEARCH or ▲/MEMORY buttons to select pressure units
(hPa/mBar/, inHg, mmHg). To confirm the selection press the PRESSURE/
ALTITUDE button.
. The “0” and the “meter” will appear on the display . Use the ▼/SEARCH or
▲/MEMORY buttons to select the altitude units . To confirm the selection
press the PRESSURE/ALTITUDE button.
. The “10” symbols will appear on the display, if meters or “” is selected
as altitude units, if “foot” is selected as altitude units. Use the ▼/SEARCH
or ▲/MEMORY buttons to set altitude. To confirm the selection press the
PRESSURE/ALTITUDE button.
Note: Setting of the pressure parameters at first launch of the unit is neces-
sary for more exact weather forecast. Default settings (in no settings are made
during 60 seconds): pressure units: hPa/mBar, mmHg, altitude units – meters,
altitude – 10 meters.
Symbolic weather forecast
Weather forecast is built according to the dynamic of atmosphere pressure mea-
suring. According to the collected data, the meteorological station can forecast
weather for the next 1- hours.
Display symbol
Forecast sunny Partly cloudy cloudy rain snow
Measuring precision is about 70%. The meteorological station forecasts pos-
sible weather that is why symbols can not correspond to the current weather.
Forecast: “sunny” for a night – means unclouded sky.
Atmosphere pressure changing tendency
Atmosphere pressure changing indication as an arrow (TREND) in the weather
forecast sector reflects changing of the atmosphere pressure (grows, constant,
falls).
Arrow
Atmospheric pressure changing grows constant falls
