Reference Altitude And Barometric Pressure - Suunto T6 User Manual

3.3.4. Reference altitude and barometric pressure

To ensure that the altimeter shows correct readings, you first have to set an accurate
reference altitude. To do this, go to a location whose altitude you have checked, for
example, with the help of a topographical map, and set the reference altitude to
match the map reading.
If you do not have accurate altitude information, you can use the current sea-level
barometric pressure as the reference value. Your Suunto t6 has a factory-set
reference altitude that corresponds to the standard barometric pressure (1013 hPa/
29.90inHg at sea level).
Setting the reference altitude
To set the reference altitude:
1. In the Alti/Baro menu, scroll to Refer and press
ENTER.
2. Altitude is the first menu item. Press ENTER to select
it.
3. Change the altitude with UP/DOWN and press ENTER.
