Description of Altimeter Function
In altimeter mode, the T-Touch Expert Solar becomes a barometric altimeter, displaying the altitude relative to mean sea level. It calculates the altitude as a function of absolute pressure (atmospheric). As the altitude rises, pressure drops, and vice versa. So the altimeter measures the difference between absolute pressure (atmospheric) and relative pressure (relative to sea level) to display the altitude.
The T-Touch Expert Solar is temperature compensated, and you can adjust your geographic location (hemisphere and climate zone). The altitude displayed is therefore corrected automatically. This makes it the ideal instrument for measuring vertical movement with the altitude difference function (e.g. in mountain trekking). The altitude difference meter indicates the elapsed time, cumulative altitude gains and losses and mean vertical speeds of ascent and descent.
