Vantage Pro Manual Page 11Chapter 2VA N T A G EPR OCO N S O L EIN S T A L L A T I O NThe Vantage Pro console is a precision instrument designed to give extremely accurate readings. As with any precision instrument, care must be used in its assembly and use. Although installation of the Vantage Pro console is relatively simple, following the steps outlined in this chapter-- and assembling the Van-tage Pro correctly from the start-- will ensure that you will enjoy all of its fea-tures with a minimum of time and effort.
Vantage Pro Console InstallationPage 12 Vantage Pro ManualCA B L E D VA N T A G EPR O CO N S O L EIN S T A L L A T I O NThe Cabled Vantage Pro is powered by 5-volt DC (direct current) with battery backup. Power may be supplied by an AC adapter, or with Davis’ optional 12 to 5-Volt Car/Boat/RV power adapter. (See “Optional Accessories” on page 10.) • WARNING: The Vantage Pro system uses power differenly from the way older Davis stations did. Use only a Davis Vantage Pro 9-volt power converter. Using an older Davis adapter will damage your Vantage Pro!Powering your Vantage ProBecause the Cabled Vantage Pro console supplies power to the sensor array through the connecting cable, you must use the AC power adapter or the optional Car/Boat/RV adapter to supply primary power. The three C-cell bat-teries provide backup power and will operate the station for four to six weeks only. 1. Insert the power adapter plug into the jack located on the right side of the console, then plug the other end of the adapter into an appropriate power outlet.The Vantage Pro should run through a brief self-test procedure. All the dis-play segments on the LCD appear and the console will beep twice. 2. Insert the C-cell battery backup.Remove the battery cover located on the back of the console. Insert 3 C bat-teries into the battery channel, negative (or flat) terminal first. Push gently on the last battery to seat all three in the channel and complete the circuit.
Cabled Vantage Pro Console InstallationVantage Pro Manual Page 13Note: To remove batteries, place the Vantage Pro Console face down on a flat, firm surface. Insert a finger-tip between the two exposed batteries. Press the middle battery down toward the notch (toward the “hidden” battery. This will relieve the tension on the first battery and allow you to withdraw it. 3. Replace the battery cover.After power-up the Vantage Pro will automatically enter Setup Mode. Setup mode will lead you through setting up and calibrating your station. See “Setup Mode” on page 22.Connecting the Cabled Vantage Pro to theIntegrated Sensor Suite (ISS)The Vantage Pro comes with 40 feet of cable. Maximum cable length from ISS to console is 1000 feet. See “Optional Accessories” on page 10 to purchase addi-tional cable.1. Gently insert the console end of the 4 conductor wire running from the ISS into the console receptacle marked ISS until it clicks into place. • WARNING: Do not force the connector into the receptacle.2. Ensure that the ISS cable is not twisted through the access hole.3. Test the connections between the ISS and the console. Spin the wind cups and change the direction of the vane. If the ISS is pow-ered and the connection between the ISS and the console is correct, you should see the wind direction and speed fields changing. Tip the rain bucket back and forth. You should see rain registering. Check the other fields to ensure you’re receiving from them, too.
Vantage Pro Console InstallationPage 14 Vantage Pro ManualWireless Vantage Pro InstallationPowering your Wireless Vantage ProBecause the Wireless Vantage Pro console does not supply power to the sensor array, an AC adapter is not required to operate the console (although you may use one if you wish). 1. Remove the battery cover from the back of the Vantage Pro console.2. Insert 3 C-cell batteries as shown. Insert the negative (or flat) terminal first. The Vantage Pro should run through a brief self-test procedure. All the display segments appear and the console will beep three times.3. Replace the battery cover. Note: Regarding Battery Use. Under normal circumstances, 3 C cell alkaline batteries should power your wireless Vantage Pro console for approximately 1 year. Davis Instruments does not recommend using rechargeable NiCad batteries with the Vantage Pro, because the Vantage Pro will not recharge them and they will not last as long.After powering up and running through its self-test mode, the Vantage Pro console will automatically enter Setup Mode. Setup Mode will lead you through setting up and calibrating your station. (See “Setup Mode” on page 22.) Establishing reception between the Wireless Vantage Pro consoleto the Integrated Sensor Suite (ISS)As you position your console, be aware of possible interference from cordless phones and other items. To prevent interference, maintain a distance of 10 feet between the Vantage Pro console and the cordless phone (handset and base). Also, for best reception, avoid positioning the console near large metallic sur-faces (e.g., most refrigerator surfaces).Please test communications between the Console/Receiver and the ISS (or other transmitter) BEFORE permanently mounting your ISS. Remember that the ISS transmits packets every few seconds. Therefore, there may be a 2 to 3 second delay before the console display updates. For more information about locating the sensor transmitter and testing reception, consult the ISS or other transmitter manual.

Alarms ModeVantage Pro Console Manual Page 35AL A R M S MO D EThe Vantage Pro features more than 30 alarms that can be programmed to sound whenever a reading exceeds a set value. With the exception of baromet-ric pressure and time, all alarms sound when a reading reaches the alarm threshold. For example, if the high outside temperature alarm threshold is set at 65 ºF, the alarm will sound when the temperature rises to 65.0 ºF. In addition, the alarm bell icon will blink repeatedly. If you are using an AC power adapter with your console, the alarm will continue to ring until you clear the alarm or until the temperature again drops below the threshold. If you are running on battery power, the alarm will beep for XX minutes only; how-ever, the bell icon will continue to blink until you clear the alarm or the temper-ature drops below the threshold.Low alarms work the same way. For example. if the wind chill threshold is set for 30 ºF, the alarm begins sounding when the temperature drops to 30.0 º and will continue flashing until the temperature again rises above 30.0º.Note: See Table “Vantage Pro Console Graphs & Alarms” on page 37 for a listing of the Vantage Pro Con-sole’s alarms.Three special alarmsETo (Evapotranspiration)ETo is updated only once an hour, on the hour. If during a given hour the ETo Value exceeds the alarm threshold, the ETo alarm sounds at the end of that hour. This is true for daily, monthly, and yearly ETo alarms. You must have the optional Solar Radiation Sensor to use this alarm. See “EvapoTranspiration (ET)” on page 54 for a description of this variable.Barometric PressureThe Vantage Pro allows you to set two barometric pressure alarms: a “rise” alarm and a “fall” alarm. You may select any rate of change per hour between 0.00 and 0.99 Hg; the Vantage Pro’s alarm will sound if the rate of change (in either direction) exceeds your threshold.TimeThe time alarm is a standard "alarm clock" type of alarm.

Vantage Pro Manual Page 47AP P E N D I X:WE A T H E RDA T AWE A T H E RCO N D IT IO N SME A S U R E D/CA L C U L A T E DThis section outlines each of the weather conditions measured/calculated by the Vantage Pro. Each section includes a brief discussion of the weather condi-tion and a listing of the various ways in which the unit displays or stores that condition. Be aware that some of the weather conditions require an optional sensor in order to measure/calculate a value (see “Optional Sensors” on page 9).WindThe Vantage Pro measures wind speed and direction from which it’s blowing. The 10 minute average wind speed is displayed in the weather ticker when wind is selected with the graph icon.TemperatureThe Vantage Pro uses the primary temperature sensor to measure the outside air temperature. A second temperature sensor in the console measures the inside air temperature. Additional temperature sensors (available only with wireless Vantage Pro) can be used to measure temperature in other locations. You may use these extra sensors to measure whatever auxiliary temperature you see fit (including water temperature).Apparent Temperature MeasuresThe Vantage Pro calculates three apparent temperature readings: wind chill, heat index, and the temperature/humidity/sun/wind index (THSW Index).
Appendix: Weather DataPage 48 Vantage Pro Manual• Wind chillWind chill takes into account how the speed of the wind affects our per-ception 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 comfy warm air surrounding the body away. The faster the wind blows, the faster heat is carried away and the colder you feel. Above 91 F, wind movement has no effect on the apparent temperature, so wind chill = the outside temperature.• Heat IndexThe Heat Index uses the temperature and the relative humidity to deter-mine how hot the air actually “feels.” When humidity is low, the appar-ent 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 saturated with water vapor) the apparent temperature “feels” higher than the actual air temperature, because per-spiration evaporates more slowly.Note: Vantage Pro measures Heat Index only when the air temperature is above 57˚ F (14˚ C), because it’s insignificant at lower temperatures. (Below 57˚, Heat Index = the air temperature.) The Heat Index is not calculated above 135˚ F (52˚ C), because calculation factors are not available.• THSW (Temperature - Humidity - Sun - Wind)Finally, like Heat Index, the THSW Index uses humidity and tempera-ture to calculate an apparent temperature. In addition, THSW incorpo-rates the heating effects of direct solar radiation and the cooling effects of wind on our perception of temperature. Note: The Vantage Pro displays THSW only if you have the optional Solar Radiation sensor.
Weather Conditions Measured/CalculatedVantage Pro Manual Page 49Relative HumidityHumidity itself simply refers to the amount of water vapor in the air. However, the amount of water vapor which the air can contain varies with air tempera-ture 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 per-centage of the amount the air is capable of holding. Relative humidity, there-fore, 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.It is important to realize that relative humidity changes with temperature, pres-sure, and water vapor content. A parcel of air with a capacity for 10 g of water vapor which 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 evapo-ration from plants and wet surfaces since warm air with low humidity has a large capacity for extra water vapor.TABLE A1: HEAT AND COLD EFFECTS
Appendix: Weather DataPage 50 Vantage Pro ManualDew-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 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 after-noon 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 (as opposed to relative humidity). High dew-point indicates high vapor content; low dew-point indicates low vapor content. In addition a high dew-point indi-cates a better chance of rain and severe thunderstorms. You can even use dew-point to predict the minimum overnight temperature. Provided no new fronts are expected overnight and the afternoon Relative Humidity ≥ 50%, the after-noon’s dew-point gives you an idea of what minimum temperature to expect overnight, since the air is not likely to get colder than the dew-point anytime during the night.RainfallThe Vantage Pro provides four separate registers for tracking rainfall totals: “rain storm”, “daily rain”, “monthly rain”, and “yearly rain”. The Vantage Pro also calculates the rate of rainfall by measuring the interval of time between each .01” or .254 mm rainfall increment.Barometric PressureThe weight of the air that makes up our atmosphere exerts a pressure on the surface of the earth. This pressure is known as atmospheric pressure. Gener-ally, the more air above an area, the higher the atmospheric pressure, this, in turn, means that atmospheric pressure changes with altitude. For example, atmospheric pressure is greater at sea-level than on a mountaintop. To compen-sate for this difference and facilitate comparison between locations with differ-ent altitudes, atmospheric pressure is generally adjusted to the equivalent sea-level pressure. This adjusted pressure is known as barometric pressure. In real-ity, the Vantage Pro measures atmospheric pressure. When you enter your loca-tion’s altitude in Setup Mode, the Vantage Pro stores the necessary offset value to consistently translate atmospheric pressure into barometric pressure.Barometric pressure also changes with local weather conditions, making baro-metric pressure an extremely important and useful weather forecasting tool. High pressure zones are generally associated with fair weather while low pres-sure zones are generally associated with poor weather. For forecasting pur-poses, however, the absolute barometric pressure value is generally less important than the change in barometric pressure. In general, rising pressure indicates improving weather conditions while falling pressure indicates deteri-orating weather conditions.Note: The following variables require optional sensors and / or stations. See “Optional Sensors” starting on page 9.
Weather Conditions Measured/CalculatedVantage Pro Manual Page 51Solar 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 horizon-tal surface. This irradiance includes both the direct component from the sun and the reflected component from the rest of the sky. The solar radiation read-ing gives a measure of the amount of solar radiation hitting the solar radiation sensor at any given time, expressed in Watts /sq. m (W/m2).Note: The Vantage Pro measures energy received in the spectral band between 400 and 1100 nm.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 sun-burn, skin cancer, skin aging, and cataracts, and can suppress the immune sys-tem. The Vantage Pro can help analyze the changing levels of UV radiation and can advise of situations where exposure is particularly unacceptable. !! CAUTION: Be aware, however, that the Vantage Pro’s UV readings do not take into account UV reflected off snow, sand, or water, which can significantly increase the amount of UV to which you are exposed. Nor does the Vantage Pro take into account the dangers of prolonged exposure to UV radiation. The readings do not suggest that any amount of exposure is safe or healthful. Do not use the Vantage Pro to determine the amount of UV radiation to which you expose yourself . Scientific evidence suggests that UV exposure should be avoided and that even low UV doses can be harmful.The Vantage Pro displays UV readings in two scales: MEDs and UV Index. MED stands for Minimum Erythemal Dose, defined as the amount of sunlight exposure necessary to induce a barely perceptible redness of the skin within 24 hours after sun exposure. In other words, exposure to 1 MED will result in a reddening of the skin. Because different skin types burn at different rates, 1 MED for persons with very dark skin is different from 1 MED for persons with very light skin.Both the U.S. Environmental Protection Agency (EPA) and Environment Can-ada have developed skin type categories correlating characteristics of skin with rates of sunburn. Tables 3a and 3b below list these skin types.

Appendix: Weather DataPage 52 Vantage Pro ManualT. B. Fitpatrick of the Harvard Medical School developed a categorization of skin types 1 through 6 which were adopted by Environment Canada. These skin types are detailed in Table 3b below. Note: More about the Fitzpatrick Skin Types is available in: Fitzpatrick TB.

Weather Conditions Measured/CalculatedVantage Pro Manual Page 53Vantage Pro can also display UV Index, an intensity measurement first defined by Environment Canada and since been adopted by the World Meteorological Organization. UV Index assigns a number between 0 and 16 to the current UV intensity. The US EPA categorizes the Index values as shown below. The lower the number, the lower the danger of sunburn. The Index value published by the U.S. National Weather Service is a forecast of the next day’s noontime UV intensity. The Index value displayed by the Vantage Pro is the result of a real-time measurement.TABLE A4: UV INDEX AND EXPOSURE CATEGORYINDEX VALUES EXPOSURE CATEGORY0 - 2 Minimal3 - 4 Low5 - 6 Moderate7 - 9 High10+ Very High UV Dose and Sunburn - Use this plot to estimate the MED dose leading to sunburn. A personwith Type II (Environment Canada) skin type might choose 0.75 MED as the maximum for theday; in contrast, a person with Type V (Environment Canada) Skin Type might consider 2.5MEDs a reasonable dose for the day. NOTE: the Vantage Pro assumes a Fitzpatrick (Environ-ment Canada) Skin Type of II.
Appendix: Weather DataPage 54 Vantage Pro ManualEvapoTranspiration (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 vegetation surfaces and the stoma of leaves) with the amount of water vapor returned through transpiration (exhal-ing of moisture through plant skin) to arrive at a total. Effectively, ETo is the opposite of rainfall, and it is expressed in the same units of measure (Inches, millimeters).The Vantage Pro uses air temperature, relative humidity, wind run1, and solar radiation data to estimate ET. (ET is calculated once an hour on the hour.) Please note that calculating ET requires the optional solar radiation sensor. (See “Optional Sensors” on page 9.)Leaf WetnessLeaf wetness (see “Optional Sensors” on page 9) provides an indication of whether the surface of foliage in the area is wet or dry by indicating how wet the surface of the sensor is. The leaf wetness reading ranges from 0 (dry) to 15.Note: Leaf Wetness is only available with the wireless Vantage Pro and the optional Leaf Wetness station.Soil MoistureSoil Moisture, as the name suggests, is a measure of the moisture content of the soil. Soil moisture is measured on a scale of 0 to 200 centibars, and can help choose times to water crops. The soil moisture sensor measures the vacuum created in the soil by the lack of moisture. A high soil moisture reading indi-cates dryer soil; a lower soil moisture reading means wetter soil.Note: Soil Moisture is only available with the wireless Vantage Pro with the optional Soil Moisture station.TimeThe Vantage Pro has a clock and a calendar for tracking time and date. The cal-endar automatically adjusts during leap years, providing you have entered the correct year in the Setup Mode.1. Wind run is a measurement of the “amount” of wind passing a given point during a specificamount of time. It’s expressed as either “miles of wind” or “kilometers of wind” and is calculatedby summing wind speed and multiplying by the time of the measurement period. For example, ifthe wind blew at an absolutely steady 10 MPH for 12 hours, you would have 120 miles of windrun (speed x time = 10 MPH x 12 Hours = 120 miles.
