La Crosse Technology WS-9057U Weather Tendency Indicator, Outdoor Temperature and Humidity Data

If the Weather station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floors of a house), discard the weather forecast for the next 48- 60 hours. By doing this, the Weather Station will not mistake the new location as being a possible change in air-pressure when really it is due to the slight change of altitude.

WEATHER TENDENCY INDICATOR

Working together with the weather icons are the weather tendency indicators (located on the left and right sides of the weather icons). When the indicator points upwards, it means that the air-pressure is increasing and the weather is expected to improve. When the indicator points downwards, the air-pressure is dropping and the weather is expected to become worse.

Taking this into account, one can see how the weather has changed and is expected to change. For example, if the indicator is pointing downwards together with cloud and sun icons, then the last noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next change in the weather will be cloud with rain icons since the indicator is pointing downwards.

If the bars are rising it means that the weather is getting better due to the increase of air pressure. If the bars go down, it means the air pressure has dropped and the weather is expected to get worse from the present time “0h“.

Note:

For accurate barometric pressure trends, the Weather Station should operate at the same altitude. For example, it should not be moved from the ground to the second floor of the house. Should the unit be moved to a new location, discard readings for the next 48-60 hours.

OUTDOOR TEMPERATURE AND HUMIDITY DATA

The fourth LCD section shows the outdoor temperature and humidity, the reception indicator, the transmitter identification number and the

MIN/MAX outdoor data.		Outdoor transmitter

TOGGLING AND RESETTING THE OUTDOOR DATA

Note: Once the weather tendency indicator has registered a change in air pressure, it will remain permanently displayed on the LCD.

AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE TREND)

The third section of the LCD also shows the relative air pressure value and the air pressure history.

Air pressure over the last 24 hours

The bar chart indicates the air pressure history trend over the last 24 hours in 7 steps, 0h, -3h, -6h, -9h, -12h, -18h, and -24h. The “0h” represents the current full hour air pressure recording. The columns represent the “hPa” (0, ±2, ±4, ±6) at specific time. The “0” in the middle of this scale is equal to the current pressure and each change (±2, ±4, ±6) represents how high or low in “hPa“ the past pressure was compared to the current pressure.

1.To toggle between the current outdoor and the MAX/MIN outdoor temperature and humidity data and the times (for temperature data only) they were recorded press the OUT/+ key:

-Once to show the MAX outdoor temperature and humidity data with the recorded time and date.

-Twice to show the MIN outdoor temperature and humidity data with the recorded time and date.

-Three times to return to the current displayed values.

2.Once the MIN or MAX data is displayed, press and hold the SET key for 3 seconds to reset the respective MIN or MAX record to

current temperature and humidity data, and current time, date display.

Note: The MIN or MAX data needs to be reset individually.
