Displaying Weather Variables Pressure Trend The pressure trend arrow indicates the current barometric trend, measured over the last three hours. The pressure trend is updated every 15 minutes. The pressure trend requires three hours of data in order to be calculated so it won’t display right away on a new station. The pressure trend is indicated on the console screen, as long as the required data is available.
Displaying Weather Variables DEW 1. Press 2ND then press DEW to select Dew Point. Dew Point is displayed in either Fahrenheit (°F) or Celsius 2ND HUM (°C) in whole degrees. See “Selecting Units of Measure” on page 26 for more information on changing the unit of measure. If the unit of measure for any temperature-related weather variable is changed, the unit of measure also changes for all temperature-related variables. See “Inside and Outside Temperature” on page 18 for more information. 2.
Displaying Weather Variables The rain values include RAIN RATE, RAIN DAY (current day’s rain total), RAIN MO (monthly rain total), and RAIN YEAR (yearly rain total).

Press RAIN to display the current rain rate. 2. 3. 4. 5. 6. 24 RAIN Rain Rate will display a number other than zero and the umbrella icon appears when two tips of the rain spoon have occurred within a 15-minute period.
Displaying Weather Variables Evapotranspiration (ET) (Optional) All the Evapotranspiration values share the same section on the console as Rain values, below the Barometric Pressure variable, on the right side.
Selecting Units of Measure Light Press LIGHT to turn on the backlight for the screen display. Press LIGHT again to turn the backlight off. Use the backlight when the LCD is not clearly visible. When the console is battery operated, the backlight remains on as long as keys are pressed. If no keys are being used, the backlight automatically turns off about fifteen seconds after it is turned on. If any key is pressed while it is turned on, it will stay illuminated for 60 seconds from the last key press.
Calibrating, Setting, and Clearing Variables Calibrating, Setting, and Clearing Variables To fine-tune your station, you can calibrate most of the weather variables. For example, if your outside temperature seems consistently too high or too low, you can enter an offset to correct the deviation. Calibrating Temperature And Humidity You can calibrate inside and outside temperature; inside and outside humidity on your Vantage Vue. 1. Press TEMP to select the temperature variable to be calibrated.
Calibrating, Setting, and Clearing Variables Calibrating Barometric Pressure Before calibrating the barometric pressure, be sure the station is set to the correct elevation. See “Screen 10: Elevation” on page 11 for more information. Find the nearest source of barometric pressure, such as a local airport, to get a current barometric pressure. 1. Press BAR to select barometric pressure. 2. Press and release 2ND, then press and hold SET. The barometric pressure variable blinks. 3.
Calibrating, Setting, and Clearing Variables To set a weather variable’s value: 1. Select the variable you wish to change (either RAIN or ET). 2. Press and release 2ND, then press and hold SET. The variable blinks. 3. Keep holding SET until all digits are lit and stop flashing. Release SET; only one digit is now blinking. 4. Press the < or > keys to select digits in the value. 5. Press the + and - keys to add to or subtract from the selected digit. 6. When you are finished, press DONE to exit.
Highs and Lows Mode Highs and Lows Mode The Vantage Vue records highs and lows for many weather conditions over three different periods: days, months, and years. Except for yearly rainfall, all high and low registers are cleared automatically at the end of each period. For example, daily highs are cleared at midnight, monthly highs are cleared at month–end midnight, yearly highs are cleared at year–end midnight. You may enter the month that you would like the Yearly Rainfall accumulation to clear.
Alarm Mode 2. Press the + and - keys to scroll through Day Highs, Day Lows, Month Highs, Month Lows, Year Highs and Year Lows. The information provided in the Weather Center displays the day of the week, month or year being viewed as well as indicates if the screen currently being viewed is displaying Highs or Lows. The reading’s time and date, where applicable, appear in the time and date fields. 3.

Chapter 4 Troubleshooting and Maintenance Vantage Vue Troubleshooting Guide While your Vantage Vue weather station is designed to provide years of trouble-free operation, occasional problems may arise. If you are having a problem with your station, please consult this troubleshooting guide before calling Davis technical support. You may be able to quickly solve the problem yourself. Please see “Contacting Davis Technical Support” on page 52.
Vantage Vue Troubleshooting Guide TABLE 4-1: TROUBLESHOOTING GUIDE Check calibration number and adjust if necessary. The ISS may need to be relocated away from radiant heat sources. See the ISS Installation manual. Inside temperature sensor reading seems too high Move the console out of direct sunlight. Make sure the console or sensor is not in contact with an exterior wall that heats up in sunlight or when outside temperature rises.

Time Appendix A Weather Data Refer to this appendix to learn more about the weather variables that are measured, displayed, and logged by your Vantage Vue station. The following variables are arranged below in the order they are viewed on the console screen: left to right, top to bottom, starting with time. Time A built-in clock and calendar track the time and date.
Forecast Forecast The forecast icons show what weather conditions may occur within the next 12 hours. The console generates a weather forecast based on the barometric reading and trend; wind speed and direction; rainfall; temperature; humidity; latitude and longitude; and time of year. The forecast is updated once an hour, on the hour and requires three hours of data. Predictions are made for cloud cover and the likelihood of precipitation.
Temperature Beaufort Scale The Beaufort Scale is an empirical measure for describing wind speed which ranks wind speeds in classes. The Beaufort Scale classification for the current wind condition is listed in the Weather Center when WIND is pressed and WxCEN is pressed several times. See “Wind Speed and Direction” on page 17 for more information. Wind Speed Beaufort Number Description 0 -1 mph; (0 -1.6 kph) 0 Calm 1-3 mph; (1.6 - 4.8 kph) 1 Light Air 3 - 7 mph; (4.8 - 11.
Wind Chill Wind Chill Wind chill takes into account how the speed of the wind affects our perception of the air temperature. Our bodies warm the surrounding air molecules by transferring heat from the skin. If there’s no air movement, this insulating layer of warm air molecules stays next to the body and offers some protection from cooler air molecules. However, wind sweeps that warm air surrounding the body away. The faster the wind blows, the faster heat is carried away and the colder you feel.
Barometric Pressure Barometric Pressure The weight of the air that makes up our atmosphere exerts a pressure on the surface of the earth known as atmospheric pressure. Generally, the more air above an area, the higher the atmospheric pressure. This means that atmospheric pressure changes with altitude. For example, atmospheric pressure is greater at sea level than on a mountaintop.

Appendix C Wireless Repeater Configuration Vantage Pro2 Wireless Repeaters (#7626, #7627) or Long-Range Wireless Repeaters (#7653, #7654) can be added to increase transmission distances or improve transmission quality between a station and a console. A repeater receives information transmitted from a Vantage Vue or Vantage Pro2 station and retransmits it to a console. Depending on transmission distance, one repeater or several repeaters can be used to collect and retransmit weather data.
