Highgear AltiTech 1 - Manual (Page 8)

BARO – Barometer
Setting Up
Press B1 until BARO is displayed (see Changing Modes). In BARO mode,
the sea level barometric pressure is displayed in the central text feild. The
units of barometric pressure are mbar, or millibars. The sea level
barometric pressure represents the prsent barometric pressure reading
reduced to sea level.
1. Press and hold B4 until the words SET WEATHER appear on top line.
2. Set current weather condition. You can scroll through Partly Cloudy,
Cloudy, Rainy, and Sunny using B2 (-) and B3 (+). To select current
weather, press B1.
3. Altitech prompts you to SET SEA LEVEL PRESSURE.
If you know the current pressure in millibars, you can calibrate the
Altitech to the exact pressure using B2 (-) and B3 (+).
Press B1 to confirm.
4. Exit setup by pressing B4
Fahrenheit and Celsius
When the temperature is displayed on the bottom line of the Barometer
mode, you can adjust the default temperature reading to Fahrenheit or
Celsius. Hold B2 for 3 seconds to change the setting. You will see the
°f or °c icon change. You can also view the other temporarily by pressing,
but not holding, B2.
Using the Barometer
The Barometer mode displays a graph of the Barometric pressure over the
past 24 hours (each bar represents 1 hour), the weather forecast, the
current barometric pressure, and the temperature at the bottom of the
screen. Pressing B3 will change the bottom display to cycle through
temperature, absolute pressure, and time. Absolute barometric pressure
is the absolute air pressure in the location of the measurement.
The weather forecast displayed with an icon at the upper left can show
Partly Cloudy, Cloudy, Rainy, and Sunny. The forecast is approximately for
the next 6-12 hours. Since the forecast is based primarily on barometric
pressure and temperature, you should use it in conjunction with
professional weather forecasts to help you plan your activities.
Note:
The thermometer takes a reading every 4 minutes, the barometer takes a reading once
an hour. This feature helps preserve battery life.
