BAROMETRIC PRESSURE: Press and hold BARO button and the Elevation (in feet or
meters) will flash. Use the UP or the DOWN ARROW button to enter the current elevation in
meters or feet. Press BARO to confirm and exit the setting.
NOTE: Elevation will automatically show in Feet if when in inHg and show in Meters when in
hPa or mb.
When in feet the numbers will change by 30 each time one of the ARROW buttons is
pressed. When in meters the numbers will change by 10.
PRESSURE GRAPH:
The vertical bars are plotted at each of the five steps and give the trend over the recorded period.
The 0 hour vertical bar will always display at the midline height to indicate the current air pressure.
The varying height of bars in other columns on the graph indicates a relative change in air
pressure up or down from the previous measurement.
New pressure measurements are compared to previously recorded pressure measurements. The
pressure change is expressed by the difference between the current ("0h") and the past readings
in divisions of ±0.06 inHg or ±2 hPa.
If the bars are rising from left to right, this indicates that the weather is improving due
to an increase in air pressure.
If the bars are falling from left to right, this indicates that the weather is expected to get
worse due to a drop in air pressure.
WEATHER FORECAST ICONS:
The unit predicts weather condition of the next 12 24 hours based on the change of atmospheric
pressure. The weather forecast is based on atmospheric pressure change and is about 70-75%
correct. As weather conditions cannot be 100% correctly forecasted, we cannot be responsible
for any loss caused by an incorrect forecast.
SUNNY PARTLY CLOUDY CLOUDY RAINY STORMY
NOTE: Any cloud icon may blink. The difference in the Rainy and Stormy icon is that the stormy
icon will blink every second indicating more severe weather.
