Vantage Pro Manual Page 9Chapter 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 10 Vantage Pro ManualCA B L E DVA N T A G EPR O CO N S O LEIN S T A L LA T IO NThe 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 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 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.

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 NPowering 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. 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 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).For more information about locating the sensor transmitter and testing recep-tion, consult the ISS or other transmitter manual.DIS P L A Y IN GT H E VA N T A G EPR O CO N S O L EYou 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 InstallationPage 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 on a tabletop, set it on a shelf, or mount it on a wall.

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.Note: (<!--Using Barometric Pressure not yet written --!> for details on the stored baro-metric pressure.Barometric Pressure: millibars (mb), millimeters (mm) and inches (in)
Chapter 3Page 26 Vantage Pro Console ManualThe table below summarizes the highs and lows stored by the Vantage Pro.ALA R M S MO D EThe 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.CONDITION HIGH LOW TIME &DATE AUTOCLEAR ADDITIONALINFORMATIONAir Temperature Yes Yes Yes YesSoil Temperature Yes Yes YesTemp/Hum Index Yes Yes YesWind Chill Yes Yes YesWind Speed Yes Yes Yes Direction of GustRate of Rainfall Yes Yes YesRelative Humidity Yes Yes Yes YesCONDITION HIGHALARM LOWALARM SPECIAL ALARM OR FEATURE“Daily” ETo Yes Hourly Update, Resets “Daily” EToTotal ETo YesTotal Degree-Days for Period YesAir Temperature Yes YesSoil Temperature Yes YesTemp/Hum Index YesWind Chill YesWind Speed Yes“Daily” Rainfall YesBarometric Pressure Rate of Change per HourRelative Humidity Yes YesDew-Point Temperature within 2˚F (1˚C) of Dew-PointTime Standard “Alarm Clock”
Graph ModeVantage Pro Console Manual Page 27The three special alarms are described below:• EToETo 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 PressureThe 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-PointThe Dew-Point alarm alerts you when the temperature comes within 2˚F (1˚C) of the dew-point.• TimeThe time alarm is a standard “alarm clock” type of alarm. It will sound for one minute.GR A P H MO D E<!-- Not yet written --!>
