Suunto T6 manual Reference altitude and barometric pressure, Setting the reference altitude

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.
