Each time you press the < key, the date moves back another day. The 26 dots in the graph field also represent each of the last 26 days, months, or years; the right-most dot is the present. As you move backward and forward the flashing dot changes to show what value is being displayed. 4. Use the console navigation keys to select a different weather variable. The console’s time displays the time of the selected variable’s high or low. 5. Press DONE to exit the Highs and Lows Mode. The console screen displays the Current Weather Mode.Note: The low reading for Wind Chill and the high reading for Heat Index are displayed in the same place. When scrolling through the high and low screens with either of these variables selected, the Wind Chill and Heat Index readings toggle on and off depending on the screen displaying. If Dew Point is selected, neither Wind Chill nor Heat will be displayed. Alarm ModeThe Vantage Vue features 22 alarms that can be programmed to sound whenever a reading exceeds or drops below a set value. With the exception of barometric pressure and time, all alarms sound when a reading reaches the alarm threshold. For example, if the high outside temperature alarm is set at 65° F/18°C, the alarm sounds when the temperature rises to or above 65.0° F/18°C. A barometric pressure alarm is triggered based on trend. A time alarm is based on a preset time. Low alarms work the same way. For example, if the wind chill threshold is set for 30°F/-1°C, the alarm condition begins when the wind chill drops to 30°F/-1°C and will continue until the wind chill rises above 30°F/-1°C.When an alarm condition exists, the audible alarm sounds, the alarm icon blinks repeatedly, and an alarm description appears in the Weather Center at the bottom of the screen. The alarm sounds for a maximum of two minutes if the console is battery-powered, but the icon continues to blink and the message stays in the Weather Center until you clear the alarm or the condition clears. If you’re using the AC adapter, the alarm will continue sounding as long as the condition exists.The alarm will sound again for each new alarm. If more than one alarm is active, the description for each active alarm along with a “+” symbol cycles onto the Weather Center section of the screen every four seconds.
Alarm Mode32Vantage Vue AlarmsSpecial AlarmsET (Evapotranspiration) (Optional)ET is updated only once an hour, on the hour. If during a given hour the ET value exceeds the alarm threshold, the ET alarm sounds at the end of that hour. This is true for daily, monthly, and yearly ET alarms. You must have the optional solar radiation sensor to use this alarm. See “Evapotranspiration (ET)” on page 46 for a description of this variable.Note: The ET Alarm is only available when the console is receiving data from a Vantage Pro2 Plus station. If your Vantage Vue console is not listening to a Vantage Pro2 Plus ISS, you cannot set an ET alarm. Barometric PressureThe Vantage Vue allows you to set two barometric pressure alarms: a “rise” alarm and a “fall” alarm. You may select any rate of change per three hours between 0.00 and 0.25 inches (6.35 mm) Hg, (8.5 mb, hPa). The alarm will sound if the rate of change (in either direction) exceeds the threshold you set. This alarm is updated every minute.Setting Alarms1.

Vantage Vue Troubleshooting Guide37Troubleshooting Reception ProblemsWhile we have tested the Vantage Vue radio extensively, each site and each installation presents its own issues and challenges. Obstructions, particularly metallic ones, can cut down your station’s reception distance. Be sure to test reception between the console and ISS in the locations you intend to install them before permanently mounting your ISS.The console’s reception status displays as an antenna icon above the graph portion of the console screen• The antenna icon displays with waves flashing around it when the console is receiving data from the ISS.• The antenna icon displays alone when the console is trying to re-establish a lost connection. When no data packets have been received for 10 minutes, the console dashes-out any missing sensor readings.• The antenna icon disappears when the connection between the ISS and console is lost. The console tries for 10 minutes to re-establish a connection, then stops trying to connect with the ISS for 15 minutes, and then redisplays the antenna alone Dew Dew Point reading seems too high or too lowCheck calibration numbers for temperature. Dew point depends on outside temperature and humidity. Make sure both sensors are working.TemperatureOutside temperature reading seems too highCheck 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 highMove 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. Make sure the console or sensor is not near a heater or other internal heat source (lamps, appliances, etc.). Check calibration number and adjust if necessary.Outside temperature seems too lowCheck calibration number and adjust if necessary. Sprinklers may be hitting the ISS radiation shield. Relocate. See ISS manual.Inside temperature sensor reading seems too lowMake sure the console temperature sensor is not in contact with an exterior wall that cools down when outside temperature drops. Make sure the console temperature sensor is not near an air con-ditioning vent. Check calibration number and adjust if necessary. ChillWind chill reading seems too high or too lowCheck calibration numbers for temperature. Wind chill depends on temperature and wind speed. Make sure they’re working.HeatHeat Index reading seems too high or too lowCheck calibration numbers for temperature. The heat index depends on temperature and outside humidity. Make sure the sen-sors are working.RainNo rain readings Make sure the rain funnel is not clogged with debris. See the ISS manual. TimeIncorrect times for sunrise and sunsetCheck your latitude, longitude, time zone, and daylight saving time settings. Sunrise and sunset times are calculated from the console using all of these settings.TABLE 4-1: TROUBLESHOOTING GUIDEProblem Solution
Console Diagnostic Mode38while it tries to re-establish a connection with the ISS. Enter and exit Setup Mode to re-display the antenna icon and manually force the console to re-establish a connection with the ISS.Check Console ReceptionEnter Setup Mode by pressing and releasing 2ND and pressing SETUP. Keep pressing DONE until the Receiving From screen displays. (See “Screen 5: Active Transmitters” on page 8 for more information.) Wait a few minutes while the console lists all the stations transmitting within range. If the console does not detect your transmitter, check the following:• Adjust the console antenna so that it is vertical and in line of sight the Vantage Vue ISS antenna. Note: The ISS antenna for the Vantage Vue can not be adjusted. Ensure that the console antenna is vertical.• Check the ISS and transmitter ID numbers. See“Screen 6: Configuring Transmitter IDs” on page 9.• Try reducing or increasing the distance between the ISS and the console. They should be at least 10 feet /3 meters apart. Maximum range is 1000’ (300m).Refer to the ISS Installation Manual for instructions on how to check the station for potential transmission problems.Console Diagnostic ModeIn addition to logging weather data, the console continuously monitors the station’s radio reception. You may find this information very helpful, especially when you are choosing locations for your console and ISS. The Console Diagnostics Mode consists of two screens, the Statistical Diagnostic Screen and the Reception Diagnostic Screen. Note: Radio transmission data used by the diagnostic screens clears each day at midnight, except for good packet graph data. Diagnostic screens are also cleared if you change your ID or go into the Setup Mode.Diagnostic Screen Commands• Press and hold TEMP, then press HUM to display the Statistical Diagnostic screen. • Press 2ND and then press CHILL to toggle between the Statistical and Reception Diagnostic screens.• Press DONE to exit the diagnostic screens.• A degree (°) sign displays to the right of the last digit in Value 3 (in the area of the compass rose, see illustration below) of the Reception Diagnostic screen (Screen 2) to differentiate which screen is currently displayed.
Console Diagnostic Mode39Screen 1: Statistical Diagnostic ScreenThe Statistical Diagnostic Screen displays information about how well data is being received from the weather station to the console. The information that is displayed in this screen includes:Note: Several of these values, with a *, are used by Davis engineers. 1. Time of day or number of times the anemometer reed switch was seen closed*. The reed switch closes once each revolution of the anemometer wind cups. Press WIND to toggle between these two values.2. Date or the number of times the anemometer reed switch was seen open*. Press WIND to toggle between these two values.Note: The time and date displays can be toggled in both statistical and reception diagnostic screens. 3. Number of packets containing received “Cyclical Redundancy Check” (CRC) errors. The system runs a CRC check on data packets. Any data packets that don’t pass this check are considered to contain errors and are discarded. These are considered bad packets. This also includes the CRC errors received during radio acquisition.4. The firmware version currently installed on the console.5. Maximum number of bad packets in a row without resynchronization.6. Number of times the console resynchronized with the transmitter. The console will attempt to resynchronize with the station after 20 consecutive bad packets.7. Percentage of good packets received. Graph shows the current and last 25 days of good packet percentage data. The scale is fixed at 10% per dot.8. The total number of bad data packets including missed packets and CRC errors. Missed packets are described as when a data packet is expected, but is not recognized as a data packet by the console. This does not include bad packets received during acquisition.9. Current streak of consecutive bad packets. The counter increments when the console is synchronized but the packet is bad. This value is reset to zero when a good packet is received.10.Current streak of consecutive good packets received.am1234567891110121314157

42TimeAppendix AWeather DataRefer 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. TimeA built-in clock and calendar track the time and date. The console automatically adjusts for daylight saving time and leap year in most of North America, and Europe (and allows manual adjustment elsewhere). The console also displays the sunrise and sunset times based on the latitude and longitude, time and date, and your time zone/UTC offset.Moon PhasesThe moon phase icons and moon phase description in the Weather Center section of console screen are calculated based on latitude and longitude, time and date and your time zone/UTC Offset. The following table displays the moon phase for the Northern and Southern Hemispheres. Icon:Northern HemisphereMoon Phase Description in the Weather CenterIcon:Southern HemisphereNEW MOON WAXING CRESCENT MOONFIRST QUARTER MOON WAXING GIBBOUS MOON FULL MOON WANING GIBBOUS MOONLAST QUARTER MOON WANING CRESCENT MOON
43ForecastForecastThe 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.WindThe anemometer measures wind speed and direction, and is part of the Integrated Sensor Suite (ISS). The console calculates a 2-minute average wind speed, a 10-minute average wind speed and 10-minute dominant wind direction. The 10- and 2-minute average wind speed is displayed in the Weather Center whenever wind has been selected on the console. The last six 10-minute dominant wind directions are included in the compass rose wind display.Forecast Icon Description of Forecasted WeatherMostly clearPartly cloudyMostly cloudyRain likelySnow likelyRain possible but not likelySnow possible but not likelyRain, freezing rain, sleet and/or snow likelyRain, freezing rain, sleet and/or snow possible but not likely
44TemperatureBeaufort ScaleThe 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.TemperatureThe ISS houses the outside temperature sensor in a vented and shielded enclosure that minimizes solar radiation induced temperature error. The console houses the inside temperature sensor. HumidityHumidity itself simply refers to the amount of water vapor in the air. However, the total amount of water vapor that the air can contain varies with air temperature and pressure. Relative humidity takes into account these factors and offers a humidity reading which reflects the amount of water vapor in the air as a percentage of the amount the air is capable of holding. Relative humidity, therefore, is not actually a measure of the amount of water vapor in the air, but a ratio of the air’s water vapor content to its capacity. When we use the term humidity in the manual and on the screen, we mean relative humidity.It is important to realize that relative humidity changes with temperature, pressure, and water vapor content. If a parcel of air with a capacity for 10 g of water vapor contains 4 g of water vapor, the relative humidity would be 40%. Adding 2 g more water vapor (for a total of 6 g) would change the humidity to 60%. If that same parcel of air is then warmed so that it has a capacity for 20 g of water vapor, the relative humidity drops to 30% even though water vapor content does not change.Relative humidity is an important factor in determining the amount of evaporation from plants and wet surfaces since warm air with low humidity has a large capacity to absorb extra water vapor.Wind Speed Beaufort Number Description0 -1 mph; (0 -1.6 kph) 0 Calm1-3 mph; (1.6 - 4.8 kph) 1 Light Air3 - 7 mph; (4.8 - 11.3 kph) 2 Light Breeze7 -12 mph; (11.3 - 19.3 kph) 3 Gentle Breeze12 - 18 mph; (19.3 - 29.0 kph) 4 Moderate Breeze18 - 24 mph; (29.0 - 38.6 kph) 5 Fresh Breeze24 - 31 mph; (38.6 - 49.9 kph) 6 Strong Breeze31 - 38 mph; (49.9 - 61.2 kph) 7 Near Gale38 - 46 mph; (61.2 -74.1 kph) 8 Gale46 - 54 mph; (74.1 - 86.9 kph) 9 Severe Gale54 - 63 mph; (86.9 - 101.4 kph) 10 Storm63 - 73 mph; (101.4 - 117.5 kph) 11 Violent Storm73 mph or above; (117.5 kph) 12 Hurricane
45Wind ChillWind ChillWind 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. Wind has a warming effect at higher temperatures.Note: There is no windchill when the air temperature is at or above 93° F (-34° C).Heat IndexThe Heat Index uses temperature and the relative humidity to determine how hot the air actually “feels.” When humidity is low, the apparent temperature will be lower than the air temperature, since perspiration evaporates rapidly to cool the body. However, when humidity is high (i.e., the air is more saturated with water vapor) the apparent temperature “feels” higher than the actual air temperature, because perspiration evaporates more slowly.Note: Heat Index and air temperature are equal at or below 0° F (-18° C).Dew PointDew point is the temperature to which air must be cooled for saturation (100% relative humidity) to occur, providing there is no change in water vapor content. The dew point is an important measurement used to predict the formation of dew, frost, and fog. If dew point and temperature are close together in the late afternoon when the air begins to turn colder, fog is likely during the night. Dew point is also a good indicator of the air’s actual water vapor content, unlike relative humidity, which takes the air’s temperature into account. High dew point indicates high water vapor content; low dew point indicates low water vapor content. In addition a high dew point indicates a better chance of rain, severe thunderstorms, and tornados. You can also use dew point to predict the minimum overnight temperature. Provided no new fronts are expected overnight and the afternoon relative humidity is greater than 50%, the afternoon’s dew point gives you an idea of what minimum temperature to expect overnight. The higher the humidity is, the more accurate the dew point prediction.Note: Dew Point is equal to the air temperature when the humidity is 100%.RainVantage Vue incorporates a tipping spoon rain collector in the ISS that measures 0.01'' or 0.2 mm for each tip of the spoon. Your station logs rain data in the same units it is measured in and converts the logged totals into the selected display units (inches or millimeters) at the time it is displayed. Converting at display time reduces possible compounded rounding errors over time. Four separate variables track rain totals: “rain rate,” “daily rain,” “monthly rain,” and “yearly rain.” Rain rate calculations are based on the interval of time between each spoon tip, which is each 0.01'' or 0.2 mm rainfall increment.
46Barometric PressureBarometric PressureThe 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. To compensate for this difference and facilitate comparison between locations with different altitudes, atmospheric pressure is adjusted to the equivalent sea level pressure. This adjusted pressure is known as barometric pressure. In reality, the Vantage Vue measures atmospheric pressure. When you enter your location’s altitude in Setup Mode, the Vantage Vue stores the necessary offset value to consistently translate atmospheric pressure into barometric pressure.Barometric pressure also changes with local weather conditions, making barometric pressure an extremely important and useful weather forecasting tool. High pressure zones are generally associated with fair weather while low pressure zones are generally associated with stormy weather. For forecasting purposes, however, the value of the absolute barometric pressure is generally less important than the change in barometric pressure. In general, rising pressure indicates improving weather conditions while falling pressure indicates deteriorating weather conditions.Evapotranspiration (ET)Evapotranspiration (ET) is a measurement of the amount of water vapor returned to the air in a given area. It combines the amount of water vapor returned through evaporation (from wet surfaces) with the amount of water vapor returned through transpiration (exhaling of moisture through plant stomata) to arrive at a total. Effectively, ET is the opposite of rainfall, and it is expressed in the same units of measure (inches, millimeters).The Vantage Vue uses air temperature, relative humidity, barometric pressure, average wind speed, and solar radiation data to estimate ET, which is calculated once an hour on the hour. Measuring ET requires that the Vantage Vue console listen to a an optional Vantage Pro2 Plus station with a solar radiation sensor installed. Solar RadiationWhat we call “current solar radiation” is technically known as Global Solar Radiation, a measure of the intensity of the sun’s radiation reaching a horizontal surface. This irradiance includes both the direct component from the sun and the reflected component from the rest of the sky. The solar radiation reading gives a measure of the amount of solar radiation hitting the solar radiation sensor at any given time, expressed in Watts/sq. meter (W/m2). Measuring solar radiation requires that the Vantage Vue console listen to an optional Vantage Pro2 Plus station with a solar radiation sensor installed. Solar Radiation is displayed in the Weather Center when ET is pressed and WxCEN is pressed multiple times.UV (Ultra Violet) RadiationEnergy from the sun reaches the earth as visible, infrared, and ultraviolet (UV) rays. Exposure to UV rays can cause numerous health problems, such as sunburn, skin cancer, skin aging, cataracts, and immune system suppression. Measuring UV radia-tion requires that the Vantage Vue console listen to an optional Vantage Pro2 Plus sta-tion with a UV radiation sensor installed. The UV Index is displayed in the Weather Center when ET is pressed and WxCEN is pressed multiple times.

51Appendix CWireless Repeater ConfigurationVantage 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.All consoles communicating with repeaters must be set up with the correct Transmitter ID and Repeater ID before the console can correctly receive station information.Setting Repeater IDTo set Repeater ID on the console:1. Press 2ND and SETUP to enter Setup Mode.2. Press DONE to display Screen 6: Configuring Transmitter IDs. See “Screen 6: Configuring Transmitter IDs” on page 9 for more information on configuring Transmitter IDs. 3. Press 2ND and then WIND to turn the repeater function on and to select a Repeater ID. Pressing 2ND and WIND sets the console to receive the signal from a repeater instead of directly from a station. The first Repeater ID displayed is repeater A.4. Press WIND repeatedly to cycle through all eight repeater IDs possible or to clear the repeater ID in the right hand corner. When no repeater ID is shown, the console is configured to listen directly to a station and not to a repeater. In this example, the console is set up to receive from an ISS station on transmitter ID 1 from repeater A. 5. Press DONE to continue to the other screens in the Setup Mode, or press and hold DONE to return to the Current Weather Mode.Clearing Repeater IDIf a repeater ID is being displayed in Screen 6 and you are not using a repeater, you must turn off the repeater function to receive station information successfully. In Setup Screen 6:Press 2ND and then press WIND repeatedly so that the console cycles through the list of repeater IDs (Repeaters A-H) until the section where the repeater ID was displayed is blank. Press DONE to continue to the next screen or press and hold DONE to return to the Current Weather Mode.
