Welcome to Davis Instruments’ Vantage Pro weather station console. The Van-
tage Pro console, part of the comprehensive Vantage Pro system, displays a
wealth of weather information -- up to ten weather variables simultaneously.
The Vantage Pro console is also a powerful weather computer, collecting, stor-
ing, and displaying historical data, including highs and lows, in graphical and
numerical formats.
The Vantage Pro also provides you with a forecast based on the latest meteoro-
logical algorithms. A quick glance at the graphical icons predicts the general
weather trend. A detailed forecast scrolls across the bottom of the screen,
including predicted xxx <!-- what? his and lows, sunny?, tornados?--!>.
Vantage Pro Formats
The Vantage Pro System is available in two formats: Cabled and Wireless.
• Cabled Vantage Pro System

The 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 Installation

The Cabled Vantage Pro is powered by 9-volt DC (direct current) with battery
backup. Power may be supplied by an AC adapter (supplied with Cabled Van-
tage Pro stations), or with the optional 12 to 9-Volt Car/Boat/RV power
adapter. (See “Optional Accessories” on page 8.)
• 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 bat-
teries provide backup power and will operate the station for only a few days.
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<!--number_!>
times.
<!--Don Raime figure here--!>
2. Insert the C-cell battery backup.
Remove the access cover located on the back of the console. Insert 3 C batter-
ies 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.
<!-- Don Raime illustration here--!>
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 28.
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 8 to purchase addi-
tional cable.
1. Remove access cover
2. Insert the console end of the 4 conductor wire running from the ISS into the console
receptacle marked ISS.
<!-- Don Raime illustration required here.--!>
3. Replace access cover
Ensure that the ISS cable is threaded through the mouse hole on the access
plate.
<!-- Don Raime illustration required here.--!>

4. 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. Look at the other
data fields to ensure they’re reporting data from the sensors.
WIR E L E S S VA N T A G EPR O IN S T A L LA T IO N
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. You may purchase
the AC adapter separately. See “Optional Accessories” on page 8.
1. Remove the access plate from the back of the Vantage Pro console.
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 dis-
play segments appear and the console will beep <!--number_!> times. <!--
same illustration as above--!>
2. 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 28.)
Connecting 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 sur-
faces (e.g., most refrigerator surfaces).
For more information about locating the sensor transmitter and testing recep-
tion, consult the ISS or other transmitter manual.

You should place the Vantage Pro computer console indoors, 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 Vantage Pro console in direct sunlight. The casing heats up in
direct sunlight. This may cause erroneous readings and / or damage to the unit.
Vantage Pro Console Installation
Page 12 Vantage Pro Manual
• Avoid placing the Vantage Pro console near radiant heaters or heating / air condi-
tioning ducts
•If you are mounting the Vantage Pro console on a wall, choose an inner or interior
wall. Avoid walls that heat up or cool down depending on the weather.
By changing the orientation of the kickstand, you may display the Vantage Pro

HIG H SA N D LO W S MO D E
<!--This section doesn’t jibe with Vantage Pro - because we don’t know how the
alarms mode will work yet--!> The Vantage Pro records highs and lows for
many weather conditions. All highs and lows represent the maximum or mini-
mum reading since the last time you cleared each individual high/low register.
If you have enabled the AutoClear for a particular high/low (see “Enabling/
Disabling AutoClear” on page 51), this reading will represent the high/low
since the time of the AutoClear. In other words, it will track highs and lows
over a 24 hour period. If you do not use AutoClear, you may track daily,
weekly, monthly, or yearly values, depending on how often you manually clear
them.
For most highs and lows, the time and date at which they occurred is stored
along with the value. Please note, however, that the date is only stored as long
as it falls within 14 days of the current date. After 14 days, the Vantage Pro dis-
plays only the high/low reading and the time; the date appears as a series of
dashes.

The Vantage Pro features a set of alarms which can be programmed to sound
whenever a reading exceeds a set value. With the exception of barometric pres-
sure, dew-point, and time, all alarms sound when a reading reaches the alarm
threshold and will continue to sound until the reading returns to within the
threshold. This means that for all high alarms, the alarm sounds when a read-
ing reaches the alarm threshold continues to sound until the reading drops
below the alarm threshold. On all low alarms, the alarm sounds when a read-
ing reaches the alarm threshold and continues to sound until the reading rises
above the alarm threshold.
The table below summarizes the Vantage Pro’s alarms.

The three special alarms are described below:
• ETo
ETo is updated only once an hour, on the hour. If during a given hour the
ETo value exceeds the alarm threshold, that information causes the ETo
alarm to sound at the end of that hour. This is true for both the “daily” and
Total ETo alarms.
In addition, for the “daily” alarm, the Vantage Pro automatically subtracts
the ETo alarm threshold value from the “daily” ETo amount after the alarm
is triggered. (This subtraction effectively clears “daily” ETo once the alarm
is triggered.) Thus, if you are using the “daily” ETo alarm (at any thresh-
old), do not use the ETo AutoClear feature because: (1) there is no need, the
value resets automatically, and (2) setting the ETo AutoClear may interfere
with triggering the alarm at the appropriate time.
A new feature in the Vantage Pro allows you to set the station to generate a
signal for every hundredth-inch of ETo. For example, if in an hour, three-
hundredths of an inch ETo is returned to the air, at the end of the hour 3 dis-
crete signals will be generated by the station. For this application, set the
alarm threshold to 0.01”, and attach an Alarm Output Module (AOM) to
receive the signal. Any other threshold (other than 0.01”) will cause the
alarm to function as normal (giving just one signal at the end of the hour
when the alarm threshold is exceeded).
Note: In order for the alternative (0.01”) setting to work, you must have an AOM connected to
your system, otherwise the ETo alarm will sound continuously. Also, make sure you set the
alarm threshold in inches (even if you are displaying total ETo in millimeters).
• Barometric Pressure
The barometric pressure alarm alerts you to changes in barometric pres-
sure. You may select a rate of change per hour (0.2”/0.4”/0.6”, 0.5 mm/
1.0 mm/1.5 mm, 0.7 hPa/1.4 hPa/2.0 hPa) and the Vantage Pro’s alarm
will sound if the rate of change (in either direction) exceeds your threshold.
• Dew-Point
The Dew-Point alarm alerts you when the temperature comes within 2˚F
(1˚C) of the dew-point.
• Time
The time alarm is a standard “alarm clock” type of alarm. It will sound for
one minute.

Wind speed reading
seems lower than
expected
Check installation by spinning wind cups.
If you get a reading, teh wind cups are
installed correctly. They should spin more
freely after an initial break-in period of
one or two weeks.
Wind speed reads 0
either all the time or
intermittently
Check installation by spinning wind cups.
If you do not get a reading, try moving the
wind cups down about 1/16” (1.5mm) on
the shaft.
If you still do not get a reading, the prob-
lem may be with the anemometer. Call fac-
tory for return authorization.
Wind speed reading
seems too high or too
low.
Check calibration number and adjust if
necessary.
