In altimeter mode, the T-Touch Connect Solar becomes a barometric altimeter and displays the altitude in relation to the average sea level. The measurement unit used to display the altitude (m or ft) is the unit that was selected in the options.

Note: Because pressure is used to calculate altitude, the altimeter is sensitive to variations in atmospheric pressure as the weather changes. It is not unusual to observe differences in altitude of 100 m in a single night. The value displayed can thus vary even though the altitude has not actually changed.

Change in the weather = pressure variation = change in the altitude displayed
