The Vantage Pro console is designed to give extremely accurate readings. As with any precision instrument, use care in its assembly and handling. Although installing the console is relatively simple, following the steps out­lined in this chapte r and as se mb ling the Vantage Pro correctly from the sta rt will help ensure that you enjoy all of its features with a minimum of time and effort.

Powering the Console

Cabled Vantage Pro Stations

Cabled Vantage Pro consoles supply power to the Integrated Sensor Suite (ISS) through the console cable. Because of the added power consumption of the ISS, the cabled console requires an AC power adapter or optional Car/Boat/RV Lighter Cord for the main power supply. The console batteries will provide backup power for up to four to six weeks.

Wireless Vantage Pro Stations

Wireless Vantage Pro consoles have been optimized to reduce power con­sumption and do not require the use of an AC adapter. You may use the included adapter if you wish, but the three C-cell batteries should power a wireless console for up to one year.
WARNING:
Note: The console does not recharge the batteries. Because of this, and because NiCad batteries will
Be sure to use the power adapter supplied with your Vantage Pro Console. Your console may be damaged by connecting the wrong power adapter.
not power the console as long as alkaline batteries, we recommend using alkaline batteries in your console.
2. Installing the Console

Installing the AC Power Adapt er

1. Find the power jack located on the bottom of the console case.
Power Plug
Wrap Cord Around Pins
2. Insert the power adapter plug into the console power jack then plug the other end of the adapter into an appropriate power outlet.
3. Check to make sure the console runs through a brief self-test procedure successfully. The console will display all the LCD segments and then beep twice.
4. After power-up the console automatically enters Setup mode. Setup mode guides you through steps required to configure the station. See “Setup Mode” on page 11 for more information.

Installing Batteries

1. Remove the battery cover locat ed o n the bac k o f the co nso le by p r es si ng down on the two latches a t the top of th e cover.

2. Insert three C batteries into the batter y chan nel, ne gative (or flat) t ermina l first.

Connecting Cabled Stations

3. Replace the battery cover. Note: To remove old batteries, see “Changing Batteries” on page 43.
Connecting Cabled Stations
Cabled Vantage Pro stations come with 100 feet (30m) of cable. Maximum cable length from ISS to console is 1000 feet. See “Opti onal Accessories ” on page 3 to purchase additional cable.
1. Gently insert the console end of the 4-conductor wire into the console receptacle marked “ISS” until it clicks into place.
To ISS
WARNING:
Do not force the connector into the receptacle.
2. Ensure that the ISS cable is not twisted through the access hole.
Note: The ISS must be assembled and powered before you can test the console connection.
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 powered 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. Also check the outside temperature and outside humidity readings, as well as readings for the optional solar and UV sensors, if installed in your station.
If you are installing a wireless station, you will be checking communications between your

console, ISS and any optional wireless stations when you perform the Setup Mode instructions located in the next chapter. See “Setup Mode” on page 11.
2. Installing the Console

Console Location

You should place the console in a location where the keyboard is easily accessible and the display is easy to read. For more accurate readings, fol­low these suggestions:
• Avoid placing the console in direct sunlight. This may cause erroneous inside temperature and humidity readings and may damage to the unit.
• Avoid placing the console near radiant heaters or heating and air conditioning ducts.
• If you are mounting the console on a wall, choose an inner or interior wall. Avoid walls that heat up or cool down depending on the weather.
• If you have a wireless co nsole , be aware o f p ossible interfe renc e from cordless phones and other devices. To prevent interference, maintain a distance of 10 feet bet ween the Vantage Pro console and a cordless phone (handset and base).
• Avoid positioning a wireles s console near large met allic surf aces such as beside a refrigerator.

Table & Shelf Place ment

The console kickstand can be set to five different angles providing five dif­ferent display angles.
1. Lean the kickstand out by pulling on its top edge.
You’ll see the indentation for your finger at the top edge of the consol e.
2. Slide the catch to arrest the kick­stand in the appropriate angle.
Choose low angles for display on a coffee table or other low area. Choose higher angles for display on a desk or shelf.
3. Pull up on the stand to close it. It will be a little tight, so it’s okay to push hard enough to get it to slide.
4. Install the two round rubber feet on the bottom of the con­sole.
Console Location
5. Install the two rubber channel feet on the kick­stand.
2. Installing the Console

Wall Mounting

The console mounts to the wall using two k eyholes located on the bac k of the case.
To mount the console on a wall:
1. Use a ruler to mark two mounting hole position s on the wa ll 8 inch es (203 mm) apart.
Drill two 3/32" or 7/64" (2.4 to 2.8mm) holes 8" (203mm) apart for the #6 x 1" mounting screws.
If you are installing a standard Vantage Pro console with sensor cable running inside the wall, mount the console over an empty switch box.
2. Use an drill a 3/32 or 7/64” (2.5 mm) drill bit to drill two pilot holes for the screws.
3. Using a screwdriver , dri ve the two #6 x 1” p an head self-thre ading screw s into the wall. Leave at least 1/8” (3 m m) between the w all the heads of the screws.
4. If the kickstand has been pulled out from the case, push it back into its upright and locked posit ion.
5. Guide the two keyholes on the back of the console over the two screw heads.

1. Check the current direction of the wind vane on the anemometer. Compare it to the wind direction reading on the console. If the wind vane is pointing south, for instance, the wind direction reading on the screen should be 180°.
If the wind direction reading is greater than 180°, subtract 180 from the reading and subtract the amount of the offset from the wind direction reading.
If the wind direction reading is less than 180°, subtract the reading from 180 and add the amount of the offset to the wind direction reading.
2. Press WIND as necessary to display the wind direction in degrees.
3. Press and release 2ND, then press and hold SET.
The wind direction variable will begin to blink.
4. Continue holding the key until the CAL message appears in the ticker.
The ticker displays the current wind direction calibration value.
Note:
5. Press < or > to select digits in the anemometer’s current reading.
6. Press + and - to add to or subtract from the anemometer reading.
7. Repeat steps 4 and 5 until you have entered the offset value from Step 1.
8. When you are finished, press DONE to exit calibration.

Alarm Mode

The Vantage Pro features more than 30 alarms that can be programmed to sound whenever a reading exceeds 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 thresh­old is set at 65 ºF, the alarm will sound when the temperature rises to 65.0 ºF.
When an alarm condition exists, the audible alarm sounds, the alarm icon blinks repeatedly, and an alarm description appears in the ticker at the bottom of the screen. The alarm sounds for a maximum two minutes if the console is battery-powered, but the icon will continue to blink and the message will stay in the ticke r until yo u clea r 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 cycles onto the screen every four seconds. A “+” sym bol app ears at the end of the alarm text if more than one alarm is tripped.
Low alarms work the same way. For example, if the wind chill threshold is set for 30 ºF, the alarm condition begins when the temperature drops to 30 º and will continue until the temperature rises above 30º.


Three Special Alarms

ET (Evapotra nspiratio n)
ET is updated only once an hour, on the hour. If during a given hour the ET Value exceeds the alarm t hreshold, the ET alarm sounds at the end of that hour. This is true fo r daily, monthly, a nd yearly ET al arms. You must have the optional Solar Radiation Sensor to use this alarm. See “Evapotranspiration (ET)” on page 50 for a description of this variable.
Barometric P ressure
The Va ntage Pro 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 0.99 Hg; the alarm will sound if the rate of change (in either direction) exceeds your threshold you set.
Time
The time alarm is a standard “alarm clock” alarm. It will sound at the time you’ve set. Make sure you choose am or pm, if you’re in 12-hour mode. It will sound for one minute.

Troubleshooting Reception Problems

While we have tested the Wireless Vantage Pro radio extensively, each site and each installation presents its own issues and challenges. Obstructions, particularly metal, will often 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, o r before permanently mounting your ISS or other transmitter(s).
You can quickly see the console’s reception status by looking at the lower right corner of the screen:
• An “X” flashes for every data packet received by the console.
• An “R” flashes when the console is trying to re-establish a lost connection.
• An “L” flashes when the signal has been lost.
• When no data packets have been received for 10 minutes, the console dashes-out any missing sensor readings
Check Console Reception
Enter Setup mode by pressing DONE, then pre ssing -. Wait a few moment s while the console list s all the stations transmitting w ithin range. If the cons ole detects your transmitter, check the following:
• Is the ID you’re receiving configured in the console? See Table “Maximum Number of Transmitters” on page 12.
• Is the correct station type set? See “Maximum Number of Transmitters” on page 12.
• Use the diagnostic screen to o bt ain useful signal stre ngth i nformat ion. See “Console Diagnostic Screen” on page42
• Adjust the console and ISS antennas to be parallel to each other.
• Try turning on the Gain. See “Diagnostic Screen Commands” on page 42.
• Reduce the distance between the ISS and the console. Move the console cl oser to the ISS, bu t make su re you’re not s tandin g
directly beneath it. Do you receive a signal?
Check the ISS

:
Refer to this appendix to learn more about the weather variables that are measured, displayed, and logged by your Vantage Pro Station.
Note:
Some weather variables require optional sensors. See “Optional Sensors” starting on page 2.

Wind

The anemometer measure s wind sp eed and directio n, and is part o f the Inte­grated Sensor Suite (ISS). The c onsol e also calcul ates a 10-mi nute a verage wind speed and 10-minute dominant wind direction. The 10-minute average wind speed is displayed in the console ticker whenever wind has been selected on the c onsole. The last six 10-minu te domina nt wind directions are included in the compass rose wind display.

Temperature

The ISS houses the outside temperature sensor in a vented and shielded enclosure that minimizes the solar radiation induced temperature error. The console houses the inside temperature sensor. Additional temperature sen­sors are available for wireless stations and can be used to measure up to eight locations.

Apparent Temperatures

Vantage Pro calculates three apparent temperature readings: wind chill, Heat Index, and the Temperature/Humidity/Sun/Wind (THSW) Index. Apparent temperatures use additional weather data to calculate what a human body perceives the temperature to be in those conditions .

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 comfy warm air surrounding the body awa y. The faster the wind blows, the fast er he at i s car­ried away and the colder you feel.

Heat Index

The 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 m ore

Appendix A: Weather Data
saturated with water vapor) the app arent tem peratu re “feels ” higher th an the actual air temperature, because perspiration 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).

Temperature/Humidity/Sun/Wind (THSW) Ind ex

The THSW Index uses humidity and temperature like the Head Index, but also includes the heating effects of sunshine and the cooling effects of wind (like wind chill) to cal culate an apparen t temperatu re of what it “feels” like o ut in the sun. The THSW Index requires a solar radiation sensor.

Humidity

Humidity itself sim ply refers to the amount of water vapor in the air . Howeve r , the 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 i s capable of ho lding. 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. A parcel of air with a capacity for 10 g of water vapor which cont ains 4 g of water vapo r , the relative hum idity 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.

Dew Point

Dew 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 and severe thunderstorms.

You can also use dew point to predict the minimum overnight temperature. Provided no new fronts are expected overnight and the afternoon Relative Humidity 50%, the afternoon’s dew point gives you an idea of what minimum temperature to expect overnight, since the air cannot get colder than the dew point anytime.

Rain

Vantage Pro incorporates a tipping-bucket rain collector in the ISS that mea­sures 0.01” for each ti p of the bucket. Your station also logs rai n d at a in i nc h units. If you select millimet ers for the rain m easurement un it, your st ation sti ll logs rain data in inches but will convert the logged totals from inches to milli­meters at the time it is displayed. Converting the logged rain totals reduces possible conversion losses to a minimum.
Four separate variables track rain totals: “rain storm”, “daily rain”, “monthly rain”, and “yearly rain”. Rain rate calculations are based on the interval of time between each bucket tip, which is each 0.01” rainfall increment.

Barometric Pressure

The weight of the air th at makes up our atmos phere exert s a press ure on the surface of the earth. This pressure is known as atmospheric pressure. Gen­erally , the more air abov e an area, the hig her the at mospheri c pressure, thi s, in turn, 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 generally adjusted to the equivalent sea-level pressure. This adjusted pressure is known as baromet­ric pressure. In reality, the Vantage Pro measures atmospheric pressure. When you enter your location’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 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 poor weather. For forecasting purposes, however, the absolute barometric pressure value is generally less imp ort a nt th an the ch ange in barometric press ure . In gen eral , rising pressure indicates imp roving wea ther co ndi tions w hile fallin g pres sure indicates deteriorating weather conditions.

Solar Radiation

What we call “ current solar radiation” is technically known as Gl obal 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 refle cted comp onent f rom th e rest of the sky. The solar radiation

Appendix A: Weather Data
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/m Solar radiation requires the solar radiation sensor.

UV (Ultra Violet) Radi ation

Energy from the sun reaches the earth as visible, infrared, and ultraviolet (UV) rays. Exposure to UV rays can caus e numerous he alt h problem s, such as sunburn, skin cancer, skin aging, and cataracts, and can suppress the immune system. The Vantage Pro can help analyze the changing levels of UV radiation and can advise of situations where exposure is particularly unacceptable. UV radiation requires the UV radiation sensor. The Vantage Pro displays UV readings in two scales : MEDs and UV Index .
CAUTION: Your station’s UV readings do not take into account UV reflected off snow, sand, or water,
which can significantly increase your exposure. Nor do your UV readings take into account the dangers of prolonged UV exposure. 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.

UV MEDs

MED stands for Minimu m Erythemal Dose, de fined as the amount of su nlight exposure necess ary to induce a b arely perce ptible redn ess of t he skin with in 24 hours after sun expo sure. In othe r words, expos ure to 1 MED wil l 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 Canada have developed skin type categories correlating characteristics of skin with rates of sunburn. See “EPA SKIN PHOTOTYPES” and “ENVIRONMENT
ANADA SKIN TYPES AND REACTION TO THE S UN” for a description of skin types.

UV Index

Vantage Pro can also display UV Index, an intensity measurement first defined by Environment Canada and since been adopted by the World Meteorological Org anization. UV In dex assigns a number between 0 and 16 to the current UV intensity. The US EPA categorizes the Index values as shown in 2. 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

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 vegetation surfaces and the stoma of leaves) with the amount of water vapor returned through transpiration (exhaling of moisture throu gh plan t skin) to arrive at a total . Effe ctive ly, ET is the opposite of rainfall, and it is expressed in the same units of measure (Inches, millimeters).
The Va ntage Pro uses air temperature, relative humidity, average wind speed, and solar radiation data to estimate ET, which is calculated once an hour on the hour. ET requires the optional solar radiation sensor.

Leaf Wetness

Leaf wetness (see “Optional Sensors” on page 2) provides an indication of whether the surface o f fo lia ge in the area is wet or dry by in dic at ing ho w wet the surface of t he sensor is. The lea f w et nes s rea din g ranges from 0 (dry ) to
15. Leaf wetness requires an optional Leaf & Soil Moisture/Temperature Station and is only available for Wireless Vantage Pro Stations.

Soil Moisture

Soil Moisture, as the name s uggest s, is a measure of the mo isture co ntent of the soil. Soil moisture is m ea sure d on a sc al e of 0 to 20 0 centibars, and can help choose times to water crops. The soil moisture sensor measures the vacuum created in the so il b y th e la ck of m oi stu re. A h igh soi l m ois tu re rea d­ing indicates dryer s oil ; a lower soil moisture reading mea ns wetter soil. Soil Moisture requires an optional Leaf & Soil Moisture/Temperature Station or Soil Moisture Station and is only availabl e f or Wireless Vantage Pro Stati ons .
