Fenix 5 wrong barometer measuring

Former Member over 8 years ago

Today I compared pro portable meteo station barometer measuring with my fenix 5. Numbers were totally different.
Portable weather station barometric pressure was: 965,9 mbar
Fenix 5 barometric measurement was: 1015,4 mbar

I'm not satisfied with fenix 5 barometric readings :/

Let me guess ... you took that pic at an Elevation of approximately 425 metres, right?

Your "pro portable meteo station barometer" was displaying absolute pressure (unadjusted air pressure) while your fenix 5 was displaying MSL pressure (absolute pressure adjusted to Mean Sea Level).

Once you know what you are looking at, it makes more sense, right?

Edit to add:

Here's a link to a handy tool you can use to enter the "P" value shown on your meteo station to see what the equivalent Po (MSL Pressure) displayed on the fenix 5 should be: http://keisan.casio.com/exec/system/1224575267

I have tried to change manually altitude on my fenix 5 to 960m and pressure on watch didn't change. I understand, that pressure in watch is probabley selected by gps altitude, how can watch by this function alert user for storm for example?

thank you
