Barometer Calibration
As barometric and altitude measurements are both based on air pressure, calibrating the barometer will automatically calibrate the altimeter. This is practical in case you don't know the altitude but have access to the internet or can call a local weather station for current barometric information.
To calibrate barometer,
1.Go to ALTI/BARO mode. If the diplay shows ALTI mode, press START twice to Activate BAROMETER. If you are already in BARO mode, proceed to step 2.
2.Press START and UP to go to Barometer CALIBRATION and press START . The Sea level PRESSURE value starts flashing on the display.
3.Enter the correct value (hPa / inHg).
4.Calibration OK is displayed for three seconds before the display returns to BARO mode.
Barometric Trend
By using the barometer to predict possible weather changes you can be better prepared and make your outdoor activity more enjoyable and safer.
If the barometric trend is rising, the weather is likely to get clearer but in cold climates, even colder weather is likely to be on its way.
If the trend is dropping, the weather is likely to get cloudier. The steeper or more rapid the drop, the greater the chance of a storm. 1hPa/hour (or
0.03inHg) drop in pressure can already signal deteriorating weather. The graph is updated every 30 minutes and displays the changes in air pressure over a rolling 24 hour period.
