Suunto LUMI manual Getting correct readings

Page 22

Suunto Lumi is combined with a memory that keeps track of your total and cumulative vertical ascents and descents. You can use the ALTIMETER profile en while biking, hiking, skiing, snowboarding, climbing – basically for whatever outdoor activity including movement in altitude that you want to monitor!

A barometer measures barometric air pressure when there is no increase or decrease in altitude. This is useful for weather forecasting. Low-pressure weather systems usually bring cloudy skies and precipitation (rain or snow), while high-pressure weather systems bring few clouds or precipitation. When the barometric pressure drops rapidly, there is a greater chance for bad weather. You can use the BAROMETER profile for any outdoor activity that does not involve changes in altitude (surfing, sailing, canoeing) – or if you just want to play meteorologist!

To help you use the right mode in the right situation, we have designed the AUTOMATIC profile that automatically switches between the ALTIMETER and BAROMETER profile depending on your whereabouts. But, even if you use the AUTOMATIC profile, your Suunto Lumi will still prompt you when it switches from the ALTIMETER to the BAROMETER profile or vice versa. Handy, isn’t it?!

6.1.2 Getting correct readings

Suunto Lumi measures the surrounding air pressure (absolute air pressure), which is affected by the altitude of the device and the weather.

If you are engaged in an outdoor activity, you need to enter the altitude reference value for your location, which is found on most topographic maps. Your Suunto Lumi will now give you the correct readings.
