Sensor Source Pressure Altitude reflects changes in ambient pressure. GPS Altitude is equal to the GPS altitude when GPS is available. Altitude defaults to the pressure altimeter when GPS is unavailable. Altimeter Settings Hold MENU, and select Sensors & Accessories > Altimeter. Barometer: Allows you to set the barometric pressure manually, or select a value from the nearest METAR station through the Garmin Connect app. Setting the current barometric pressure manually can help to improve the accuracy of the pressure altitude reading. Altitude Alert: Sets an alarm to vibrate when you reach a specified altitude. The altitude alert is not available in watch mode. Sync to Elevation: Allows you to synchronize the watch to your current elevation manually. Set Standard Baro: Allows you to set the standard barometric pressure. Calibrating the Barometric Altimeter Your watch was already calibrated at the factory, and the watch uses automatic calibration at your GPS starting point by default. You can manually calibrate the barometric altimeter if you know the correct elevation. 1 Hold MENU. 2 Select Sensors & Accessories > Elevation > Calibrate. 3 Select an option: • To enter the current elevation manually, select Enter Manually. • To enter the current elevation from the digital elevation model, select Use DEM. • To enter the current elevation from your GPS location, select Use GPS. Barometer Settings From the barometer glance, press START, and select Settings. Calibrate: Allows you to manually calibrate the barometer sensor. Plot: Sets the time scale for the chart in the barometer glance. Storm Alert: Sets the rate of barometric pressure change that triggers a storm alert. Sensor Mode: Sets the mode for the sensor. The Auto option uses both the altimeter and barometer according to your movement. You can use the Altimeter Only option when your activity involves changes in altitude, or the Barometer Only option when your activity does not involve changes in altitude. Pressure: Sets how the watch displays pressure data. Calibrating the Barometer Your watch was already calibrated at the factory, and the watch uses automatic calibration at your GPS starting point by default. You can manually calibrate the barometer if you know the correct elevation or the correct sea level pressure. 1 From the watch face, press UP or DOWN to view the barometer glance. 2 Press START to open the glance. 3 Press START to view the settings menu. 4 Select Settings > Calibrate. 5 Select an option: • To enter the current elevation and sea level pressure (optional), select Enter Manually. • To calibrate automatically from the digital elevation model, select Use DEM. • To calibrate automatically from your GPS starting point, select Use GPS. Elevation Settings Hold MENU, and select Sensors & Accessories > Elevation. Calibrate: Allows you to calibrate the altimeter sensor manually. Elevation: Sets the units of measure for elevation. Wireless Sensors Your watch can be paired and used with wireless sensors using ANT+ or Bluetooth technology (Pairing Your Wireless Sensors, page 58). After the devices are paired, you can customize the optional data fields (Customizing the Data Screens, page 23). If your watch was packaged with a sensor, they are already paired.
