5.2 Calibrating the altitude IAC+
The RoX 10.0 gps’s altitude measurement is determined on the basis of the
barometric air pressure. Any change to the weather means a change to the
air pressure, which can lead to a change to your current altitude. To offset
these changes in air pressure, you must enter a reference altitude into the
RoX 10.0 gps (process known as calibration).
The RoX 10.0 gps offers three types of calibration (only one has to be used):
1. Home altitude 1–3
The home altitude is the altitude of your start location. you can set three
different home altitudes.
2. Current altitude
The current altitude is the altitude at your current location. The current
altitude is used if you are out on your bike and altitude information is
provided.
3. Air pressure at sea level
If you are at an unknown altitude, you can enter the ‘air pressure reduced to
sea level’ to calculate the current altitude. The air pressure reduced to sea
level can be found online (e.g. www.meteo24.de), in the daily newspaper, or at
airports.
