Vantage Pro Console Installation
C A B L E D V A N T A G EP R O C O N S O L EI N S T A L L A T I O N
The 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 Pro
Because 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 batteries 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 display 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 batteries 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.

Vantage Pro Manual
Cabled Vantage Pro Console Installation
Note: To remove batteries, place the Vantage Pro Console face down on a flat, firm surface. Insert a fingertip 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 the
Integrated 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 additional 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 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. Check the other fields to
ensure you’re receiving from them, too.
Vantage Pro Manual

Vantage Pro Console Installation
Wireless Vantage Pro Installation
Powering your Wireless Vantage Pro
Because 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 console
to 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 surfaces (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.

Setup Mode lets you choose settings that determine how your Vantage Pro station operates.
Entering & Exiting Setup Mode
The console will automatically enter Setup Mode when you first power up.
Later, if you need to make any changes, access the Setup Mode at any time by
pressing the “DONE” and “down arrow” keys at the same time. Exit Setup at
any time by pressing and holding the “DONE” key until the “Current
Weather” screen appears.
Setup Mode Screens
On entering the Setup Mode, a sequence of screens will appear on the console.
Pressing “DONE” will take you to the next screen in the sequence.
Setup Mode - Screen 1: Transmitters
Screen 1 displays active transmitters located in your area. The ticker will display the message “Receiving from...” and the active transmitter IDs will be illuminated. The rest of the display screen will be blank. Transmitters must be
switched on for the console to recognize them. This screen requires no input; it
simply shows you what transmitters the console can receive.
Setup Screen 1: Transmitters. This screen shows the Console receiving
transmssions from transmitter IDs 1 and 4.
Press and release the “DONE” key to move to Setup screen 2.
Note: Each Vantage Pro Console/Receiver may receive signals from up to eight different
transmitters ; however, only certain combinations of transmitters are possible. Table 1 below lists
the maximum numbers of transmitter types each console/receiver can handle:

Setup Mode - Screen 2: Selecting Transmitters
Use setup screen 2 to tell the Console/Receiver which transmitter IDs to listen
to, and what kind of station each transmitter represents.
Setup Screen 2: Here’s what should greet most new Vantage Pro owners. The console comes factory pre-set at transmitter ID 1. “ON” means the console will receive
signals from that ID and will assume the transmitter is an ISS. For most owners, this
will complete this step. See the ISS manual for further details.
You probably do NOT need to change transmitter IDs. The default transmitter
ID for the ISS is ‘1’. Your console/receiver will assume that Station 1 is your ISS
and should find its transmissions automatically. This should complete Setup
screen 2 for most owners.
In the unlikely event that you do need to change transmitter IDs (e.g. a neighbor is using a Davis product nearby or you have more an optional transmitter
(See “Optional Sensors” on page 9.) read on. Otherwise, skip down to Setup
Screen 3.
To activate reception on different ID codes, press the LEFT or RIGHT arrow
key, or the “STATION” key, to scroll between transmitter IDs.
Note: Station IDs do not have to be in order. The factory default transmitter ID for the ISS is “1”.
See your transmitter’s manual to learn how to set the transmitter ID.
Vantage Pro Console Manual
Page 23
Chapter 3
• Once you’ve settled on the ID you wish to use, use the "+" or "-" arrow keys to activate reception of that ID code.
As each different ID illuminates, the ticker will display the word “ON” or
“OFF”. “ON” means the Console/Receiver will “listen” to that transmitter’s signal. “OFF” means the Console/Receiver will ignore signals from
that transmitter.
• Now, press the “GRAPH” key to change the type of station assigned to each transmitter number.
When a station is listed as “ON”, one of the possible station types will be
displayed in the ticker: ISS, TEMP, HUM,TEMP HUM, WIND, LEAF, or
SOIL. Press the “GRAPH” key to scroll through this list until the correct
station type appears.
Press and release the “DONE” key to move to Setup screen 3.
Setup Mode - Screen 3: Retransmit
The Vantage Pro Console/Receiver can re-transmit data to other Console/
Receivers, or to the Davis Weather Echo and Weather Echo Plus.
Note: This feature is not available in the cabled Vantage Pro station.
Setup screen 3 lets you switch the retransmit feature on or off. Use the "+" or "-"
arrow key to choose “Retransmit On” or “Retransmit Off”. Use the STATION
key to choose and assign a transmission ID to the Console/Receiver. Note that
only IDs you’re not already using will appear.
Press and release the DONE key to move to Setup screen 4.
Setup Mode - Screen 4: Time & Date
Use the UNITS key to choose 12 or 24 hour time display. Use the LEFT and
RIGHT arrow keys to move between hours and minutes fields. Use the "+" and
"-" keys to enter digits. When entering the date, use the UNITS key to select
Month/Day or Day.Month display. Enter the month, day, and year.
Setup Mode - Screen 5: Latitude
To give you the best forecast we can, as well as calculate the correct times for
sunset and sunrise for your location, the Vantage Pro Setup will ask you to
enter your latitude and longitude.
Note: Latitude and longitude are a way of identifying your position on the earth. Latitude measures distance north or south of the equator. Longitude measures distance east or west of the Prime Meridian,
an imaginery line running north and south through Greenwich, England. (The Prime Meridian was set
by international convention at this location in 1884.)
Page 24
Vantage Pro Console Manual
Setup Mode
If you do not know your latitude and longitude, there are several ways to find
out. Many atlases include latitude and longitude lines. You can also talk to the
reference department of your local library, or try calling your local airport. The
more accurate you are, the better; however, a reasonable estimate will work,
too.
Use the LEFT and RIGHT arrow keys to move between numbers. Use the "+"
and "-" arrow keys to change digits. Use the UNITS key to specify North or
South (of the equator). Press and release the DONE key to move to Setup
screen 6.
Setup Mode - Screen 6: Longitude
Enter your longitude as above. Use the UNITS key to specify EAST or WEST
(of the Prime Meridian). Press and release the DONE key to move to Setup
screen 7.
Setup Mode - Screen 7: Time Zone
Use the "+" and "-" keys to choose a time zone. If your time zone is not shown,
use the 2ND key to enter your raw Greenwich Mean Time (GMT) offset in 15
minute increments. Press and release the DONE key to move to Setup screen 8.
Setup Mode - Screen 8: Daylight Savings Detection
Use the "+" and "-" keys to choose Auto or Manual. Most users in North America, including Mexico, may select Auto (excepting Saskatchewan, Indiana, Arizona & Hawaii). All other users should choose Manual. Press and release the
DONE key to move to Setup screen 9.
Setup Mode - Screen 9: Daylight Savings Status
If you chose “Manual” in screen 7, use the "+" and "-" arrow keys to turn Daylight Savings Time on or off. If you chose “Detect” in screen 7, the console will
display the appropriate setting, based on the current time and date. Press and
release the DONE key to move to screen 10.
Setup Mode - Screen 10: Elevation
Meteorologists standardize barometric pressure data to sea level so that surface
readings are comparable, whether they’re taken on a mountainside or by the
ocean. For the Vantage Pro to make this same standardization and ensure accurate readings, enter your elevation in this screen.
Use the LEFT and RIGHT arrow keys to move between fields. Use the "+" and
"-" keys to select digits. Use the UNITS key to select feet or meters. Press and
release the DONE key to move to Setup screen 11.
If you do not know your elevation, there are several ways to find out. Many
atlases and almanacs include elevation for cities and towns. You can also talk to
the reference department of your local library. The more accurate you are, the
better; however, a reasonable estimate will work, too.
Setup Mode - Screen 11: Wind Cup Size
Vantage Pro Console Manual
Page 25
Chapter 3
All Vantage Pro Stations come with large wind cups. Switch this setting to
small only if you have separately purchased and installed small wind cups.
Use the "+" and "-" arrow keys to switch between large and small. Press and
release the DONE key to move to Setup screen 12.
Note: Large wind cups are more sensitive to low wind speeds and are the best choice for most users. Small
wind cups are less sensitive at low wind speeds; however, they are more resilient. Only install small
wind cups if you expect winds over 120 mph (194 kph).
Setup Mode - Screen 12: Rain Collector
Your Vantage Pro is pre-configured for the included rain collector. Simply press
“DONE” to move to the next screen. You may change the rain display’s units

Alarms Mode
AL A R M S MO D E
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.
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; however, the bell icon will continue to blink until you clear the alarm or the temperature 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 Console’s alarms.
Three special alarms
ETo (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 Pressure
The 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.
Time
The time alarm is a standard "alarm clock" type of alarm. It will sound for one
minute.

This section outlines each of the weather conditions measured/calculated by
the Vantage Pro. Each section includes a brief discussion of the weather condition 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).
Wind
The 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.
Temperature
The 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 Measures
The Vantage Pro calculates three apparent temperature readings: wind chill,
heat index, and the temperature/humidity/sun/wind index (THSW Index).
Vantage Pro Manual
Page 47
Appendix: Weather Data
• 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 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 Index
The Heat Index uses the 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 saturated with water vapor) the apparent
temperature “feels” higher than 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), because calculation factors are not available.
• THSW (Temperature - Humidity - Sun - Wind)
Finally, like Heat Index, the THSW Index uses humidity and temperature to calculate an apparent temperature. In addition, THSW incorporates 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.

TABLE A1: HEAT AND COLD EFFECTS
Relative Humidity
Humidity 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 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.
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 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 for extra water vapor.
Vantage Pro Manual
Page 49
Appendix: Weather Data
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 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. Dewpoint 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 indicates a better chance of rain and severe thunderstorms. You can even use dewpoint 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 is not likely to get colder than the dew-point anytime
during the night.
Rainfall
The 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 Pressure
The 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. Generally, 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 compensate for this difference and facilitate comparison between locations with different altitudes, atmospheric pressure is generally adjusted to the equivalent sealevel 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
important than the change in barometric pressure. In general, rising pressure
indicates improving weather conditions while falling pressure indicates deteriorating weather conditions.
Note: The following variables require optional sensors and / or stations. See “Optional Sensors” starting on
page 9.

Weather Conditions Measured/Calculated
Solar Radiation
What 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. m (W/m2).
Note: The Vantage Pro measures energy received in the spectral band between 400 and 1100 nm.
UV (Ultra Violet) Radiation
Energy 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, 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.
!! 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 Canada have developed skin type categories correlating characteristics of skin with
rates of sunburn. Tables 3a and 3b below list these skin types.

UV Dose and Sunburn - Use this plot to estimate the MED dose leading to sunburn. A person
with Type II (Environment Canada) skin type might choose 0.75 MED as the maximum for the
day; in contrast, a person with Type V (Environment Canada) Skin Type might consider 2.5
MEDs a reasonable dose for the day. NOTE: the Vantage Pro assumes a Fitzpatrick (Environment Canada) Skin Type of II.
Vantage 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 realtime measurement.

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 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 Wetness
Leaf 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 Moisture
Soil 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 indicates 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.
Time
The Vantage Pro has a clock and a calendar for tracking time and date. The calendar 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 specific
amount of time. It’s expressed as either “miles of wind” or “kilometers of wind” and is calculated
by summing wind speed and multiplying by the time of the measurement period. For example, if
the wind blew at an absolutely steady 10 MPH for 12 hours, you would have 120 miles of wind
run (speed x time = 10 MPH x 12 Hours = 120 miles.
