EC EMC Compliance

This product complies with the essential protection requirements of the EC EMC Directive 2004/108/ EC; Low Voltage Directive 2006/95/EC; and Eco-Design Directive 2005/32/EC>0.5 watt no-load adapter.

Introduction

The Integrated Sensor Suite (ISS) collects outside weather data and sends the data to a Vantage Pro2 console or Weather Envoy. Wireless and cabled versions of the ISS are available, as well as Standard and Plus versions. The Wireless ISS is solar powered and sends data to the console via a low-power radio. The Cabled ISS sends data and receives power via the console cable.

Note: If you are using a wireless ISS, it can transmit to a Vantage Pro2 console, as well as a Davis Van-

tage Vue console or Davis Weather Envoy. One ISS can transmit to any number of receivers within its range, so you can add additional consoles to use in different rooms.

The standard version of the ISS contains a rain collector, temperature sensor, humidity sensor and anemometer. In addition to the standard weather features, the ISS Plus adds a pre-installed solar radiation sensor and an ultra-violet (UV) radiation sensor. Temperature and humidity sensors are mounted in a passive radiation shield to minimize the impact of solar radiation on sensor readings. The anemometer measures wind speed and direction and can be installed adjacent to the ISS or apart from it. See “Locating the ISS and Anemometer” on page 17 for siting guidelines.

On an ISS Plus, the additional solar and UV sensors are mounted next to the rain collector cone. Separate solar and UV sensors are available to upgrade a standard ISS.

The Sensor Interface Module (SIM) contains the “brains” of the ISS and the radio transmitter. The SIM is located on the front of the radiation shield in the SIM box. The SIM collects outside weather data from the ISS sensors and then transmits the data to your Vantage Pro2 console or Weather Envoy.

Included Components and Hardware

The ISS comes with all the components and hardware shown in the following illustrations. If you purchased your ISS as part of a weather station package containing the Vantage Pro2 console, additional components may be included in the package that are not shown here.

Preparing the ISS for Installation

Note: If the ISS is a Plus model and contains UV and solar sensors, do not touch the small white diffusers

on top of the sensors. Oil from skin reduces their sensitivity. If you are concerned that you have touched the diffusers at any time during the installation, clean the UV diffuser using ethyl alcohol with a soft cloth. When cleaning the UV diffuser, DO NOT use rubbing or denatured alcohols because they can affect accuracy of the sensor readings. Ethyl alcohol can be procured through an industrial or laboratory supply store. Clean the solar diffuser with a soft damp cloth.

3. Use the Allen wrench provided to tighten the set screw on the side of the wind cups. The wind cups should drop slightly when you let go.

Note: Ensure that the set screw is screwed in fully and very tight. Failure to do so will cause the

anemometer to function improperly.

4. Spin the wind cups. If the wind cups spin freely, the anemometer is ready and can be set aside while you prepare the rest of the ISS for installation.

Note: If the wind cups don’t spin freely, take them off and repeat the wind cup installation process.

Check SIM Sensor Connections

The SIM is located in the housing on the front of the ISS station. The SIM contains all the connections for the weather sensors of the ISS. Follow the steps below to check the SIM and ensure that all sensors are connected properly.

Open the SIM Box

1. Locate the white box with the solar panel containing the SIM on the front of the ISS unit. The cabled model does not have a solar panel.

2. Locate the white tab at the bottom center of the SIM box cover.

3. Lift the tab away from the box while sliding the cover up. Look on the side of the SIM box. The box cover can be easily removed from the box when the alignment indicator on the cover is lined up with the alignment indicator on the box

4. Lift the cover off the box, being careful not to stress the solar panel cable when removing the cover.

The SIM and sensor connectors are visible once the SIM cover has been removed.

Check SIM Sensor Connections

Note: See “SIM Board Display and Contents” on page 29 for information on locating the components

and points of interest on the SIM board.

Optional: Disconnect the solar panel connection

The solar panel on the box cover is connected to the SIM by a wire. If the cover cannot be set aside while still connected to the SIM box safely, it should be disconnected from the SIM box. To disconnect the solar power connection:

1. Locate the brown connector for the solar power wire.

2. Pull the connector outward off the brown solar power tab. The solar panel is no longer connected to the SIM.

3. Set the SIM cover aside.

Check the Factory Installed Sensor Connections

1. Verify that the rain collector and temperature/humidity sensor cables are plugged into the receptacles labeled RAIN and TEMP/HUM on the SIM.

2. If the station includes UV and/or solar radiation sensors, verify that the sensor cables are plugged into the receptacles labeled UV and SUN on the SIM.

Check SIM Sensor Connections

Connect the Anemometer Cable to the SIM

1. Unwind the coil of cable enough to work with the anemometer.

Note: Do not unwind the entire coil of anemometer cable at this time.

access port entirely, leaving no holes or gaps large enough for weather or insects.

Note: If you are assembling a cabled station, wait to reinsert the foam until cable assembly is com-

plete. See “Cabled ISS Assembly” on page 8.

Once the sensor connections have been checked and the anemometer cable has been inserted, a connection between the ISS and the Vantage Pro2 console must be made.

7. Follow the instructions that best apply to your ISS and console:

• See “Cabled ISS Assembly” on page 8 for assembling Vantage Pro2 weather sta-

tions that contain a cabled connection between the ISS and the console.

• See “Wireless ISS Assembly” on page 11 for assembling Vantage Pro2 weather

stations that use a wireless connection to transmit and receive data.

Cabled ISS Assembly

The Cabled ISS system contains a cable for connecting the ISS to a Vantage Pro2 cabled console. Once the anemometer has been installed and the sensors have been checked, a cabled connection between the ISS and the console can be established. Follow the steps below for powering the ISS and connecting to the console.

Applying Power

The 100' (30 m) console cable provides power to the ISS and is used to send data from the ISS to the console. The console cable can be extended up to 1000' (305 m) in length with extension cables purchased from Davis Instruments.

1. Locate the 100' console cable included with your system.

2. Pull the foam insert out of cable access port, if it has been reinserted, and set the foam aside.

3. Insert the console connector cable end into the cable access port from beneath the SIM box. Slide the cable through the cable access port with the connector tab down.

4. On the SIM, firmly insert one end of the 4-conductor cable into the modular connector located apart from the sensor connectors next to the battery insert. This connector is labeled COMM. If you haven’t powered up the console yet, refer to the installation instructions in the Vantage Pro2 Console Manual and apply power to the console.

5. On the back of your console, insert the other end of the console cable into the modular receptacle labeled “ISS.”

6. Firmly insert the foam in between the cables and at the top of the cable access port, taking care to ensure that the foam seals the access port entirely, leaving no holes or gaps for weather or insects. See the graphic on page 6 for more information on inserting the foam insert. Plugging the console cable into the console powers the ISS and establishes communication between the ISS and the console. The ISS should immediately begin collecting weather data and start sending the data to the console.

Verifying Communication with the Console

Use these steps to verify reception of ISS data at the Cabled Vantage Pro2 console and to test the operation of the ISS sensors.

1. If the console is in Setup Mode, press and hold DONE until the Current Weather screen displays. Sensor readings from the ISS should display on the screen.

2. Near the center of the screen, look for the outside temperature.

3. Spin the wind cups to check wind speed, pressing WIND if necessary to alternate between speed and direction in the compass rose.

4. Turn the wind vane and allow five seconds for the wind direction display to stabilize before moving it again. Approximately one minute after power-up the outside relative humidity reading should be displayed on the console.

Troubleshooting Cabled ISS Communication

5. If the ISS contains a UV sensor and/or solar sensor, press 2ND and then press RAIN YR for current ultraviolet readings or press 2ND then press RAIN DAY for solar radiation readings. The UV reading displays in the center of the console. The solar reading displays in the bottom right corner of the console display. UV and solar readings should be zero or close to zero if the ISS is inside. Zero is a valid reading. Dashes(--) are displayed if no data comes from the sensors.

6. Current weather data displayed on the console confirms communication. Once the ISS has been powered and the console has successfully received accurate readings from all the sensors, prepare the ISS for installation. Continue on to “Preparing the ISS for Installation” on page 15 for more information. If the communication problems still exist between the cabled ISS and the console, see “Troubleshooting Cabled ISS Communication” below. To ease the installation process of ISS at a location, disconnect the console cable from the SIM. Remove the foam and slide the cable out through access port. Once a location for both the ISS and the console has been arranged, reinsert the cable through the access port, into the console connector, and reinsert the foam.

Troubleshooting Cabled ISS Communication

If the console is not receiving sensor readings from the ISS, please try the following troubleshooting procedures.

• Check the console to make sure it is being powered with the AC adapter sup-

plied in the Vantage Pro2 packaged box or three C batteries.

Note: The supplied adapter is a five-volt positive center AC to DC adapter. Other adapters may not work if

Note: If the LED is flashing rapidly, call Technical Support. See “Contacting Davis Instruments” on

the voltage or adapter type is different.

• Make sure the cable is firmly plugged into the ISS jack on the console.

• Make sure that the cable is firmly plugged into the correct jack on the SIM.

• Verify that all sensor cables are firmly plugged in.

• An LED indicator light on the SIM flashes each time the ISS transmits, which is

about once every 2.5 seconds. If the LED remains dark, there is a problem with the ISS transmitter. Call Technical Support. See “Contacting Davis Instruments” on page 27.

See “SIM Board Display and Contents” on page 29 for information on locating the LED indicator light and the DIP switches.

page 27 for more information.

If the console is still not receiving readings, ensure that the console is in Setup Mode and reboot the console by disconnecting the AC power adapter from the console and removing the console batteries for at least 30 seconds. If the console is still not displaying sensor readings from the ISS, please contact Davis Technical Support.

Wireless ISS Assembly

The ISS has a wireless connection to a Vantage Pro2 wireless console. Once the anemometer has been installed and the sensors have been checked, the ISS must be powered and a wireless communication channel must be established between the ISS and the console. Follow the steps below for powering the ISS and establishing a connection to the console.

• Applying Power to a Wireless ISS

• Verifying Communications with the Console

• Verifying Data from the ISS Sensors

• Troubleshooting ISS Reception

Applying Power to a Wireless ISS

1. Insert the 3-volt lithium battery into the SIM. Once powered, the ISS immediately begins transmitting data to the console.

Be sure to match the “+” sign on the battery with the “+” sign on the SIM. See “SIM Board Display and Contents” on page 29.

The SIM stores energy from the solar panel for power at night. The battery is an alternative power source the SIM uses when it is depleted of energy.

Checking Transmitter ID

A Vantage Pro2 console can receive data from up to eight different wireless stations. The default Transmitter ID for the ISS and console is 1.

1234

In most cases it will not be necessary to change the Transmitter ID. The console and ISS should begin communicating automatically when power is applied.

Note: If it is necessary to change the Transmitter ID, remember to use the same ID for the ISS and con-

sole. See “SIM Board Display and Contents” on page 29 for locating the components and points of interest on the SIM board.

Settings for Transmitter ID 1:

DIP Switch 1 = OFF DIP Switch 2 = OFF DIP Switch 3 = OFF

Verifying Communication with the Console

1. Power the console if it does not already have power. Refer to the Vantage Pro2 Console Manual and apply power to the console.

The console automatically enters Setup Mode when powered up.

2. If the console is not in Setup Mode, press and hold DONE then press the down arrow. The message RECEIVING FROM... and STATION NO. followed by the Transmitter IDs that the console detects displays on the console screen.

3. Look for the ISS Transmitter ID. The number 1 displays unless the Transmitter ID has been changed. If the console displays the ISS Transmitter ID, the ISS is detected.

Note: If the console does not display the number of the ISS Transmitter ID setting, see “Troubleshooting

Wireless ISS Reception” on page 12 for more information. It can take several minutes for the console to acquire and display all the available Transmitter IDs.

4. Press and hold DONE to view ISS data once the ISS Transmitter ID displays.

Verifying Data from the ISS Sensors

Use these steps to verify reception of ISS data at the wireless Vantage Pro2 console and to test the operation of the ISS sensors.

1. Press and hold DONE until the Current Weather screen displays, if the console is in Setup Mode. Sensor readings from the ISS should display on the screen.

2. Near the center of the screen, look for the outside temperature.

3. Spin the wind cups to check wind speed, pressing WIND if necessary to alternate between speed and direction in the compass rose.

4. Turn the wind vane, and allow 5 seconds for the wind direction display to stabilize before moving it again. Approximately one minute after power-up the outside relative humidity reading should be displayed on the console.

5. If the ISS contains a UV sensor and/or solar radiation sensor, press 2ND and then press RAIN YR for current ultraviolet readings or press 2ND then press RAIN DAY for solar radiation readings. The UV reading displays in the center of the console. The solar reading displays in the bottom right corner of the console display. UV and solar readings should be zero or close to zero if the ISS is inside. Zero is a valid reading — dashes are displayed if no data comes from the sensors.

6. Current weather data displayed on the console confirms successful communication.

Once the ISS has been powered and the console has successfully received accurate readings from all the sensors, prepare the ISS for installation. Continue on to “Preparing the ISS for Installation” on page 15 for more information.

If the communication problems still exist between the wireless ISS and the console, see “Troubleshooting Wireless ISS Reception.”

Troubleshooting Wireless ISS Reception

If the console isn’t displaying data from the ISS, perform the following steps:

1. Verify that the console is powered and is not in Setup Mode.

2. Make sure that all ISS sensor cables are firmly connected to the SIM and the ISS battery is properly installed.

3. Walk around the room with the console, standing for a few moments in various locations, to see if you are picking up signals from the ISS. Look on the screen’s lower right corner. An “X” toggles on and off when the console receives a transmission.

4. If you do not see the “X” slowly blinking, no matter where you stand with the console, put your ISS in Test Mode.

• The DIP switch #4 on the SIM is the Test Mode

switch. Switch it to the ON position, using a ballpoint pen or paper clip.

• An LED indicator light on the SIM flashes each

time the ISS transmits, which is about once every

2.5 seconds.

Troubleshooting Wireless ISS Reception

Note: If the LED is flashing rapidly, call Technical Support. See “Contacting Davis Instruments” on

page 27 for more information.

See “SIM Board Display and Contents” on page 29 for information on locating the components and points of interest on the SIM board.

5. If the LED remains dark, there is a problem with the ISS transmitter. Call Technical Support. See “Contacting Davis Instruments” on page 27.

6. If the LED flashes repeatedly but your console isn’t picking up a signal anywhere in the room, it could be related to one of the following causes:

• You changed the ISS Transmitter ID at the ISS or console, but not at both.

• Reception is being disrupted by frequency interference from outside sources.

Interference has to be strong to prevent the console from receiving a signal while in the same room as the ISS. In high-interference environments, it may be preferable to install the Cabled Vantage Pro2.

• There is a problem with the console.

7. If a problem with receiving the wireless transmission still exists, please contact Technical Support. See “Contacting Davis Instruments” on page 27.

8. When you are finished testing wireless transmission, set DIP switch # 4 to OFF to take the SIM out of Test Mode.

Note: If the SIM is left in Test Mode, the blinking LED will significantly reduce ISS battery life.

Optional: Changing ISS Transmitter ID

Each wireless transmitting station, including the Integrated Sensor Suite (ISS), uses one of eight selectable Transmitter IDs. DIP switches #1, 2 and 3 on the transmitter control the ID — or channel — the station transmits on. DIP switch #4 is used for transmission testing, not for the Transmitter ID.

Note: The transmitter on the ISS and receiver on the console communicate with each other only when

both are set to the same ID.

The default Transmitter ID is 1 for both the ISS and the Vantage Pro2 console, and should work fine for most situations. Change the Transmitter ID if any of the following issues are true:

• Another Davis Instruments wireless weather station operating nearby

already uses Transmitter ID 1.

• Additional Vantage Pro2 or Vantage Vue wireless transmitting stations have

been purchased with the Vantage Pro2 or Vantage Pro2 Plus and one of the stations has been designated as Station No. 1 instead of the selected ISS.

On the ISS, the Transmitter ID is set using the DIP switches located on the Sensor Interface Module (SIM). To access the SIM, open the SIM housing cover. See “Open the SIM Box” on page 5.

ple, a network can either have both a Leaf Wetness/Temperature station and a Soil

Moisture/Temperature station, or it can have one combined Leaf Wetness and Soil

Moisture/Temperature station.

Preparing the ISS for Installation

Once all the sensors have been connected and communication between the ISS and the console has been successfully established, continue to prepare the ISS unit for installation. The steps for preparing the ISS for installation are as follows.

• Close the SIM Box

• Prepare the Solar Panel

• Prepare the Rain Collector

• Site the ISS and Anemometer

Close the SIM Box

To close the SIM box and continue assembling the ISS:

1. If the solar panel wire was disconnected during ISS assembly, reconnect the wire on the SIM box cover to the solar panel tab on the SIM board.

Note: See “SIM Board Display and Contents” on page 29 for information on locating the solar panel tab.

2. Find the two raised alignment indicator lines on both the SIM box and the SIM box cover. Match these alignment indicators as you place the cover against the box.

3. Slide the cover down until it snaps securely in place.

Prepare the Rain Collector

The tipping bucket is secured at the factory to protect it from damage during shipping. To use the ISS properly, the bucket must be released. To release the bucket:

1. Remove the rain collector cone from the ISS base by rotating the cone counter-clockwise. When the cone’s latches line up with openings in the base, lift the cone off the ISS base. When new, the cone fits tightly in the base and may require extra pressure to remove. Steady the ISS base between your knees when removing the cone.

Twist to Open

Prepare the Rain Collector

2. Carefully cut and remove the plastic tie that holds the tipping

bucket in place during shipping (usually yellow or white in color).

3. On your console screen, look for the DAILY RAIN display. If the console is cabled to the ISS, reconnect the cable and see if the console is receiving rain readings.

4. While watching the daily rain

Cut the

display, tip the bucket until it drops to the opposite side, then wait to see if the display registers a rain reading. Each tip indicates 0.01" or 0.2 mm of rain and may take up to a minute to register at the console. If the bucket is tipped too quickly, the number on the console display may not change.

5. Temporarily reinstall the rain collector cone until you are ready to mount the ISS outside. If you are installing the metric measurement adapter, do not reinstall the rain collector cone.

Optional: Insert the Metric Measurement Adapter

The rain collector tipping bucket mechanism contains a standard measurement weight magnet that takes measurements in 0.01'' (US versions) or 0.2 mm (UK and EU versions). If you have a US version and would like to convert it to a metric measurement, follow these steps.

Note: EU and UK versions have the metric measurement installed at the factory.

The ISS hardware kit contains a metric adapter that adjusts the weight of the tipping bucket mechanism so that it reports 0.2 mm metric measurements for every tip of the bucket. To install the metric adapter:

1. Find the metric adapter included in the hardware.

2. Locate the magnet between the arms of the bucket.

3. Open the arms slightly with one hand while pulling the magnet out with the other.

Open plastic tipping mechanism arms, pull out magnet

4. Separate an end cap from one end of the magnet.

Locating the ISS and Anemometer

For the weather station to perform at its best, use these guidelines to select the optimum mounting locations for the ISS and anemometer. Be sure to take into consideration ease of access for maintenance, sensor cable lengths and wireless transmission range when siting the station.

Note: When selecting a location for installing your ISS, especially on a rooftop, make sure it is a location

far from power lines. Seek professional help if you uncertain about the safety of your installation.

Locating the ISS and Anemometer

General ISS Siting Guidelines

• Place the ISS away from sources of heat such as chimneys, heaters, air conditioners and exhaust vents.

• Place the ISS at least 100' (30 m) away from any asphalt or concrete roadway that readily absorbs and radiates heat in the sun. Avoid installations near fences or sides of buildings that receive a lot of sun during the day.

• Ideally, place the radiation shield of the ISS 5' (1.5 m) above the ground in the middle of gently sloping or flat, regularly mowed grassy or naturally landscaped area that drains well when it rains. For areas with average maximum yearly snow depths over 3' (0.9 m), mount the ISS 2' (0.6 m) above this depth.

• Never install the ISS where it will be directly sprayed by a sprinkler system because it will adversely affect the readings.

• Avoid installations near bodies of water such as swimming pools or ponds.

• Do not locate the ISS under tree canopies or near the side of buildings that create “rain shadows." For heavily forested areas, site the ISS in a clearing or meadow.

• Site the ISS in a location with good sun exposure throughout the day if the ISS is wireless or includes solar radiation or UV radiation sensors.

For agricultural applications (important for evapotranspiration (ET) calculations):

• Install the ISS and anemometer as a single unit with the radiation shield 5'

(1.5 m) above the ground and in the middle of the farm between similar crop types (i.e. two orchards, two vineyards or two row crops), if possible.

• Avoid areas exposed to extensive or frequent applications of agricultural chemi-

cals (which can degrade the sensors).

• Avoid installation over bare soil. The ET formula works best when the ISS is

installed over well-irrigated, regularly mowed grass.

• If the last three guidelines cannot be met, install the weather station at the edge

of the primary crop of interest.

Anemometer Siting Guidelines

• For best results, place the anemometer at least 7' (2.1 m) above surrounding obstructions such as trees or buildings that obstruct wind flow.

• If mounting on a roof, mount the anemometer at least 7' (2.1 m) above the roof apex (when using a Mounting Tripod, install the anemometer at the very top of the pole).

• If mounting the ISS and the anemometer together, such as on a pole or a wooden post, mount the anemometer so it is at least 12'' (0.3 m) above the top of the rain collector cone for best results.

• The standard for meteorological and aviation applications is to place the anemometer 33' (10 m) above the ground. Seek professional help for this type of installation.

• The standard for agricultural applications is to place the anemometer 6' (2 m) above the ground. This is important for evapotranspiration (ET) calculations.

Note: For roof mounting, and ease of installation, we recommend using the optional mounting tripod

(#7716). For other installations, use the Mounting Pole Kit (#7717).

NOAA on the Davis Support web site (http://www.davisnet.com/support/weather).

Locating the ISS and Anemometer

Optional: Anemometer Cable Length Considerations

• All Vantage Pro2 stations include a 40' (12 m) cable to go between the ISS and the anemometer. This can be extended up to 540' (165 m) using optional extension cables purchased from Davis Instruments.

Anemometer Cable

• If most of the anemometer cable length is unused, the coiled cable length can be stowed once the anemometer and ISS have been installed on a site. Attaching the anemome-

Cable Tie

ter cable to the mounting pole using the supplied cable tie is the recommended option.

Keep the anemometer cable coiled if possible during the ISS and anemometer assembly so that it is easily stowed once installation is complete.

• The Cabled Vantage Pro2 includes a 100' (30 m) cable to go between the console and the ISS. This can be extended up to 1000' (300 m) using optional cables.

Optional: Wireless Transmission Considerations

The range of the radio transmission depends on several factors. Try to position the transmitter and the receiver as close as possible for best results.

Typical maximum ranges include:

• Line of sight: 1000' (300 m).

• Under most conditions: 200 - 400' (60 - 120 m).

Other range and transmission considerations include:

• Range may be reduced by walls, ceilings, trees, foliage, a metal roof or other large metal structures or objects such as aluminum siding, metal ducts, and metal appliances, such as refrigerators, televisions, heaters, or air conditioners.

• Frequency interferers also reduce transmission distance. Cordless phones (900 Mhz) are a common example of frequency interference.

• Transmission between wireless units may be obscured by something unidentifiable, or by some obstacle that can’t be worked around.

• For best results, orient the ISS antenna and the console antenna so that the orientation and angles of the antennas are parallel to each other.

Locating the ISS and Anemometer

If your ISS is directly overhead, the orientation illustrated here might work best.

(

For best reception, orient antennas so they are parallel to each other.

• If possible, align the pivot joints of both the ISS and the console antennas so that they are facing each other for maximum signal strength.

• The ISS and console antennas do not rotate in a complete circle. Avoid forcing the antennas when rotating it.

• Turn the gain on to improve reception of a weak signal. Refer to the Vantage Pro2 Console Manual for information on setting the console gain.

• Consider using a Wireless Repeater (#7626 or #7627) or Long-Range Wireless Repeater (#7653 or #7654) to strengthen the signal or to increase the distance between the ISS and the console.

Testing Wireless Transmission at ISS Location

After a suitable place has been found for the wireless ISS, it is very important to test reception from the installation location before permanently mounting it there.

1. Set the ISS in the desired installation location.

2. Set the console in the desired location.

3. Press and hold TEMP and press HUM to display statistical and reception diagnostics on the console.

• It’s a good idea to test the console’s reception anywhere that you might want to

use or mount it now or in the future. Take your time. If you aren’t picking up a strong signal where you intend to place your console, try rotating the antenna on the console and ISS or try moving the console and ISS to different positions.

• Irregular terrain in the area may interfere with the signal. For example, if the ISS

is mounted downhill from the console, the ground may block a large percentage of the transmitted signal.

4. Press and hold DONE to return to the Current Weather Mode when finished testing.

Note: See the Troubleshooting section of the Vantage Pro2 Console Manual for information on how to

check wireless signal strength and for more information on troubleshooting reception problems.

Installing the ISS

The anemometer and the main part of the ISS can be installed either together as a single unit on a pole, or apart from each other. The main part of the ISS includes the rain collector, the temperature and humidity sensors, the radiation shield, and the SIM housing. Use the U-bolts to install the ISS and anemometer together or separately on a pole. Use the lag screws to install them separately on a flat, vertical surface.

• The anemometer comes with a 40' (12 m) cable for flexibility in configuring the system to monitor wind conditions. For example, the anemometer could be mounted at the highest point of a roof, and the ISS could be mounted on a fence closer to ground level.

General ISS Installation Guidelines

• Install the ISS as level as possible to ensure accurate rain measurements. Use the

built-in bubble level (under the rain collector cone, near the tipping bucket mechanism) or carpenter’s level to make sure the ISS is level.

• In the Northern Hemisphere, the solar panel should face south for maximum sun

exposure.

• In the Southern Hemisphere, the solar panel should face north for maximum sun

exposure. Either install the ISS and anemometer separately, each facing north, or mount them as a single unit with solar panel facing north and the wind vane reoriented to the South.

Optional: Guidelines for Securing Cables

• To prevent fraying or cutting of cables, secure them so

they will not whip about in the wind.

• Secure cable to a metal pole using cable ties or by

wrapping tape around both the cables and the pole.

• Place clips or ties approximately every 3' – 5' (1 –

1.6 m).

• Mounting clips, cable ties or additional hardware not included with your station can be easily obtained at a hardware or electronics store.

Note: Do not use metal staples or a staple gun to secure cables. Metal staples — especially when

installed with a staple gun — have a tendency to cut the cables.

Cable Clip

Cable Tie

Orient the Wind Vane

The wind vane rotates 360° to display current and dominant wind directions on the compass rose of the console display. To obtain accurate readings, the vane must be correctly oriented when mounting the anemometer outside. By default, the wind vane reports the correct wind direction if the anemometer arm points true north.

To ensure correct orientation of the wind vane, mount the anemometer so that the arm points true north.

The wind vane will be ready for use immediately.

If your anemometer arm cannot be mounted aiming true north, you will need to calibrate the wind direction on your console to display accurate wind directions. See your Vantage Pro2 Console Manual.

Installing the ISS on a Flat Surface

Installation Instructions

There are several ways to mount and install the ISS unit. The following are installation types that Davis Instruments recommends. Individual ISS locations and installations may vary.

• Installing the ISS on a flat surface

• Installing the anemometer on a post or flat surface

• Installing the ISS on a pole

Note: All installations require that the rain collector cone be removed for assembly. Use the built-in bubble

level to ensure the main part of the ISS is level.

Installing the ISS on a Flat Surface

Refer to the following illustration to install the ISS on a post or flat, vertical surface.

1/4" Flat Washers

1/4" Lock Washers

1/4" x 3" Lag Screws

Note: Typically the anemometer and rain collector are mounted on opposite sides of the post. They are shown mounted on adjoining sides to clarify the installation details.

Option 1: Installing the ISS on a Post or Flat Surface

1. With a 3/16" (5 mm) drill bit, drill two holes approximately 21/8" (54 mm) apart. Use a carpenter’s level to ensure the holes are level. Use the metal backing plate as a guide when marking the holes.

2. Remove the rain collector cone if it is installed on the ISS mounting base.

3. Insert the 1/4" x 3" lag screws through the metal backing plate and the holes in the mounting base into the post. Make sure the ISS is level by checking the built-in bubble level.

4. Tighten the lag screws using an adjustable wrench or 7/16’’ wrench.

5. Re-attach the rain collector cone. Set the cone back on the base so its latches slide downward into the latch openings on the base. Rotate cone clockwise.

6. Place the debris screen (shown in the illustration on page 1) inside the cone, “feetdown” over the funnel hole.

Installing the ISS on a Pole

Option 2: Installing the Anemometer on a Post or Flat Surface

1. With a 3/16" (5 mm) drill bit, drill two holes approximately 21/8" (54 mm) apart. Use a carpenter’s level to ensure the holes will be level.

2. Insert the 1/4" x 3" lag screws through the flat washers and the holes in the anemometer mounting base into the post.

3. Tighten the lag screws using an adjustable wrench or 7/16" wrench.

Note: If your anemometer cannot be mounted aiming true north, you will need to calibrate the wind direc-

tion on your console to display accurate wind directions. See your Vantage Pro2 Console Manual.

Installing the ISS on a Pole

When installing the ISS on a pole, the rain collector and radiation shield section of the ISS can be mounted as a single unit with the anemometer section, or the two sections can be mounted separately.

Refer to the following illustration when installing the ISS and/or anemometer on a pole.

Accessories for Pole Mounting

• Use the Mounting Tripod (#7716) for easy roof-mounting.

• Use the Mounting Pole Kit (#7717) to raise the installation height of the ISS by

up to 37.5" (0.95 m).

General Guidelines for Installing on a Pole

• With the supplied U-bolts, the ISS and anemomter can be mounted on a pole

having an outside diameter ranging from 1

• Larger U-bolts (not supplied) can be used to mount to a pole with a maximum

outside diameter of 2

/2" (64mm).

/4" to 13/4" (32 – 44mm).

• To mount on a smaller pole, obtain a U-bolt that fits the base openings but that

has a shorter threaded section. If mounting on a smaller pole with the included U-bolts, the bolt interferes with the rain collector cone.

• Use the built-in bubble level to ensure ISS is level.

Installing the ISS on a Pole

Guidelines for Installing the ISS on a Pole

• When mounting the ISS and anemometer together on opposite sides of the pole,

remember that whichever side is mounted first, the U-bolt from the opposite side must also be placed around the pole before tightening the U-bolts. (If it is not, there is no way to slide it in later.)

• In each side’s mounting base, there is a groove to accommodate the other’s U-

bolt.

• Once the two sides of the ISS have been loosely mounted together on the pole,

swivel the unit to the correct direction and then tighten the hex nuts. The desired height can also be achieved by sliding the ISS vertically.

Option 1: Installing ISS and Anemometer Together

Try to install the ISS so the anemometer arm is aiming north.

Note: If your anemometer arm cannot be mounted aiming true north, you will need to calibrate the wind

direction on your console to display accurate wind directions. See your Vantage Pro2 Console Man-

ual.

1. Place the U-bolt for the anemometer around the pole so that its round end fits in the top groove of the side of the rain collector side’s plastic mounting base. The groove is right above two large holes.

2. While holding the mounting base of the rain collector against the pole, place the two ends of the remaining U-bolt around the pole and through the two holes in the base.

3. Slide the metal backing plate over the bolt ends as they stick out over the rain collector base. Secure the backing plate with a lock washer and hex nut on each of the bolt ends as shown previously.

Note: Do not tighten the hex nuts yet. Leave the hex nuts loose to swivel the ISS base on the pole.

4. The two ends of the anemometer’s U-bolt should now be pointing away from the mounted rain collector side. Slide the anemometer’s mounting base over the protruding bolt ends. Place a flat washer, a lock washer and a hex nut on each of the bolt ends as shown above. Do not tighten the nuts yet.

5. Raise the ISS unit to the desired height on the pole and swivel it so the anemometer arm is pointing north.

6. Using an adjustable wrench or 7/16" wrench, tighten all four hex nuts until the ISS is firmly fastened on the pole.

7. Re-attach the rain collector cone by setting the cone back on the base so its latches slide downward into the latch openings on the base, then rotate cone clockwise.

8. Place the debris screen (shown in the illustration on page 1) inside the cone, “feetdown,” over the funnel hole. When installing the ISS as a single unit, we recommend tucking the coil of anemometer cable between the rain collector cone and the ISS base.

Option 2: Installing ISS Only

1. While holding the mounting base against the pole, place the two ends of a U-bolt around the pole and through the two holes in the base.

2. Slide the metal backing plate over the bolt ends as they stick out toward the rain collector cone. Secure the backing plate with a washer, a lock washer, and a hex nut on each of the bolt ends. Do not tighten the nuts yet.

Finishing the Installation

For the wireless ISS, swivel the ISS base so the solar panel is facing south (in the Northern Hemisphere), or north (in the Southern Hemisphere).

3. Tighten the hex nuts using an adjustable wrench or 7/16" wrench.

4. Re-attach the rain collector cone. Set the cone back on the base so its latches slide downward into the latch openings on the base. Rotate the cone clockwise.

5. Place the debris screen (shown in the illustration on page 1) inside the cone, “feetdown,” over the funnel hole.

Option 3: Installing Anemometer Only

1. While holding the mounting base against the pole, place a U-bolt around the pole and through the two holes in the base.

2. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.

3. Swivel the anemometer until the arm is pointing north.

Note: If your anemometer arm cannot be mounted aiming true north, you will need to calibrate the wind

direction on your console to display accurate wind directions. See your Vantage Pro2 Console Man-

ual.

Finishing the Installation

Level the Solar and UV Sensors

If you have a Vantage Pro2 Plus station that includes a solar radiation or UV sensor, use the bubble level on the sensors as a guide to verify that the sensors are level.

Adjust the level by tightening or loosening the screws that hold each sensor onto the shelf.

Note: If you are installing the solar or UV sensors separately, see the Sensor Mounting Shelf installation

manual and the Solar Radiation and UV Sensor installation manuals for more information.

Clearing Data Collected During Testing and Installation

Now that the ISS is mounted outside, any data that was collected in the Vantage Pro2 console during testing and mounting can be cleared.

To clear all the collected data on the console:

1. Press WIND so that graph icon appears adjacent to the wind data on the display. Confirm that wind speed is displayed on the compass rose.

2. Press 2ND, then press and hold CLEAR for at least six seconds and until you see “CLEARING NOW” in the console ticker display.

Additional Mounting Option

Extending Wireless Transmission Range

Optional repeater stations can be used to extend the wireless transmission range.

• Wireless Repeater, AC-Powered (#7626)

• Wireless Repeater, Solar-Powered (#7627)

• Long-Range Wireless Repeater, AC-Powered (#7653)

• Long-Range Wireless Repeater, Solar-Powered (#7654)

Additional Mounting Option

Extending the Console Cable (Cabled ISS Only)

A cabled ISS can be extended up to 1000' (300 m) away from the console by using Davis Instruments extension cables (#7876).

Relocating the Anemometer

Using Extension Cables:

Note: Not all cables are compatible with your Vantage Pro2 system. To be sure they will work, order Davis

extension cables from your dealer or directly from Davis Instruments.

The anemometer can be extended further than 40' from the ISS by using Davis Instruments extension cables (#7876).

Be aware that the maximum measurable wind speed reading decreases as the total length of cable from the anemometer to the ISS increases.

Note: If the cable length is greater than 540' (165m), the maximum measurable wind speed may be less

than 100 MPH (161 km/h).

Using the Anemometer Transmitter Kit (Wireless ISS Only)

Use the Anemometer Transmitter Kit (#6332) to add an independent wireless transmitter to the anemometer. The kit allows the anemometer to function as a transmitter station sending wind data directly to the console, instead of transmitting via the ISS.

Remote Mounting the Solar Radiation and UV Sensors

The solar radiation and UV sensors have a 3' (0.9 m) cable. If you wish to install these sensors away from the ISS, you can extend the length of the sensor cables up to 125' (38 m) with Davis Instruments extension cables (#7876).

Optional Wireless Stations

You may use our optional wireless sensor stations to collect weather measurements, without the inconvenience of routing cables.

• Wireless Temperature Station (#6372)

• Wireless Temperature/Humidity Station (#6382)

• Wireless Leaf & Soil Moisture/Temperature Station (#6345)

For more details, please visit our website or see the most recent Davis Precision Weather Instruments catalog.

Maintenance and Troubleshooting

Maintaining UV and Solar Radiation Sensors

If the ISS is a Plus model and contains UV and solar radiation sensors, do not touch the small white diffusers on top of the sensors. Oil from skin reduces their sensitivity. If you are concerned that you have touched the diffusers at any time, clean the UV diffuser using ethyl alcohol with a soft cloth. When cleaning the UV diffuser, DO NOT use rubbing or denatured alcohols because they can affect accuracy of the sensor readings. Ethyl alcohol can be procured through an industrial or laboratory supply store. Clean the solar diffuser with a soft damp cloth.

Due to the sensitivity of ultraviolet and solar radiation sensors it is common practice for manufacturers to recommend re-calibration after a period of time. Users demanding high accuracy typically recalibrate their sensors annually. Here at Davis Instruments, we have seen less than 2% drift per year on the readings from these sensors.

Contact Technical Support about returning your sensor for calibration. See “Contacting Davis Instruments” on page 27.

Cleaning the Radiation Shield

The outer plating of the radiation shield should be cleaned when there is excessive dirt and build-up on the plating. Use a damp cloth to clean the outer edge of each ring.

Note: Spraying down or using water excessively to clean the radiation shield can damage the sensitive

sensors or alter the data and readings the ISS is transmitting.

Check the radiation shield for debris or insect nests at least once a year and clean when necessary. A buildup of material inside the shield reduces its effectiveness and may cause inaccurate temperature and humidity readings.

To thoroughly clean the radiation shield:

1. Remove the rain collector cone.

2. Using a Phillips head screwdriver, loosen the three 4'' (~100mm) screws holding the radiation shield plates together.

3. Taking care to maintain the order in which the five plates are assembled, separate the plates as shown and remove all debris from inside the shield.

Troubleshooting

Note: For some models of the ISS, the order in which the five radiation shield plates are assembled may

be slightly different than the order shown in the figure on page 25. For this reason, ensure that you always reassemble the plates in the same order in which they were disassembled.

4. Reassemble the plates in the same order in which they were disassembled, and fasten them together using a Phillips head screwdriver to tighten the 4" screws, as shown in the illustration.

Cleaning the Rain Collector Cone

To maintain accuracy, thoroughly clean the rain collector several times a year.

Note: Cleaning the rain collector and tipping buckets my cause false rain readings. Unplug the RAIN sen-

sor from the SIM before cleaning so that no inaccurate readings are logged, or clear the weather data that was logged on the Vantage Pro2 console after cleaning is complete. See your Vantage Pro2 Console Manual for instructions on clearing weather data.

1. Separate the cone from the base by turning it counter-clockwise.

2. Use a soft, damp cloth to remove any debris from the cone, cone screen, and tipping bucket.

3. Use pipe cleaners to clear the funnel hole in the cone and drain screens in the base.

4. When all parts are clean, rinse with clear water.

5. Re-attach the cone and replace the debris screen.

Troubleshooting

If a Sensor Functions Intermittently

Carefully check all connections from the sensor to the ISS. See “Check SIM Sensor Connections” on page 4.

Loose connections account for a large portion of potential problems. Connections should be firmly seated in receptacles and plugged in straight. To check for a faulty connection, try jiggling the cable while looking at the display. If a reading displays intermittently on the console as the cable is jiggled, the connection is faulty. Try removing and then re-installing the cable to correct the faulty connection. If the sensor still functions intermittently contact Technical Support. See “Contacting Davis Instruments” on page 27.

Most Common Rain Collector Problem

If the rain collector seems to be under-reporting rainfall, remove the rain collector cone to clean the tipping bucket and clear out any debris. Make sure the cable tie around the tipping bucket has been cut and removed.

Most Common Anemometer Problems

“The anemometer head is tilted when I mount the anemometer.”

With the Allen wrench provided in the supplied hardware, loosen the screws holding the anemometer head on the arm. (The screws are on the bottom of the anemometer head, by the wind cups.) Turn the anemometer head so it is straight and then tighten the screws.

Troubleshooting

“The wind cups are spinning but my console displays 0 mph.”

The signal from the wind cups may not be making it back to the display. Remove the cups from the anemometer (loosen the set screw). Put the cups back onto the shaft and make sure to slide them up the shaft as far as possible. Check your cables for visible nicks and cuts. Look for corrosion in the WIND connector on the SIM and on splices in the cable. If using an extension cable, remove it and test using only the anemometer cable. Contact Technical Support and ask for a wind test cable if the problem has not been resolved.

Note: If the anemometer is sending no data, the wind display indicates 0 speed and a north direction.

“The wind direction is stuck on north, or displays dashes.”

It is likely that there is a short somewhere between the wind vane and the display. Check the cables for visible nicks and cuts. Look for corrosion in the “WIND” jack on the SIM and on splices in the cable (if any). If possible, remove any extensions and try it with the anemometer cable only. If none of these steps get the wind direction working, contact Technical Support and ask for a wind test cable.

“The wind cups don’t spin or don’t spin as fast as they should.”

The anemometer may be located where wind is blocked by something, or there may be friction interfering with the cups’ rotation. Remove the wind cups (loosen the set screw) and clear out any bugs or debris. Turn the shaft the cups rotate on. If it feels gritty or stiff, contact Davis Technical Support.

Note: Do not lubricate the shaft or bearings in any way. When replacing the cups, make sure they are not

rubbing against any part of the anemometer head.

“Readings aren’t what I expected them to be.”

Comparing data from your ISS to measurements from TV, radio, newspapers, or a neighbor is NOT a valid method of verifying your readings. Readings can vary considerably over short distances. How you site the ISS and anemometer can also make a big difference. If you have questions, contact Technical Support.

Welcome to Vantage Pro2

Welcome to your Vantage Pro2 Weather Station console. The console displays and records your station’s weather data, provides graph and alarm functions, and interfaces to a computer using our optional WeatherLink Vantage Pro2 stations are available in two basic versions: cabled and wireless. A cabled Vantage Pro2 station transmits outside sensor data from the Integrated Sensor Suite (ISS) to the console using a straight-through four-conductor cable. A wireless Vantage Pro2 station transmits outside sensor data from the ISS to the console via a low-power radio.

Note: Wireless consoles can also collect data from optional Vantage Pro2 sensors or a

Davis Vantage Vue ISS, and can also retransmit data to other Vantage Pro2 or Vantage Vue consoles or a Davis Weather Envoy. You can have an unlimited number of consoles - one in each room!

The Vantage Pro2 Quick Reference Guide included with your station provides an easy to use reference for most console functions.

Chapter 2

Installing the Console

The Vantage Pro2 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 chapter and assembling the Vantage Pro2 correctly from the start will help ensure that you enjoy all of its features with a minimum of time and effort.

Powering the Console

Cabled Vantage Pro2 Stations

Cabled Vantage Pro2 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 used as the main power supply. The console batteries provide backup power for up to four to six weeks.

Wireless Vantage Pro2 Stations

Wireless Vantage Pro2 consoles 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 nine months.

Note: When using an AC Power adapter, be sure to use the power adapter supplied with

your Vantage Pro2 Console. Your console may be damaged by connecting the wrong power adapter. The console does not recharge the batteries. Because of this, and because NiCad batteries do not power the console as long as alkaline batteries, use alkaline batteries in the console.

Installing the AC Power Adapter

1. Remove the battery cover located on the back of the console by pressing down on the two latches at the top of the cover.

2. Find the power jack located on the bottom of the console case.

Power Plug

3. Insert the power adapter plug into the console power jack, then plug the other end of the adapter into an appropriate power outlet.

Wrap Cord Around Pins

Installing Batteries

4. Check to make sure the console runs through a brief self-test procedure successfully. On power up, the console displays all the LCD segments and beeps twice. A message displays in the ticker banner at the bottom of the console, followed by the first screen that displays during Setup Mode. Press and hold DONE to skip the message and enter into Setup Mode.

Setup Mode guides you through steps required to configure the station. See “Setup Mode” on page 9 for more information.

Installing Batteries

1. Remove the battery cover located on the back of the console by pressing down on the two latches at the top of the cover.

Battery

2. Insert three C batteries into the battery channel, negative (or flat) terminal first.

3. Replace the battery cover.

Connecting Cabled Stations

Cabled Vantage Pro2 stations come with 100 feet (30m) of cable. This cable is used for connecting the console to the ISS. Maximum cable length from ISS to the console using Davis Instruments cables is 1000 feet. To connect the console to the ISS:

1. Firmly insert the console end of the straight-through four-conductor wire into the console receptacle marked “ISS” until it clicks into place. Do not force the connector into the receptacle.

To ISS

Console Location

2. Ensure that the ISS cable is not twisted through the access port.

Note: The ISS must be assembled and connected to the console so that it is receiving

power before the console connection can be tested.

Once the console and ISS are both powered up, cable connection should be tested and established.

Once the console is powered, it automatically enters Setup Mode. You can step through the Setup Mode options, or exit the Setup Mode to test the connection and sensor readings in Current Weather Mode. See “Setup Mode” on page 9 for Setup Mode options. See “Current Weather Mode” on page 18 for viewing and verifying current weather data coming from the cabled console.

To verify that the console is receiving data from the ISS through the console connection, see “Cabled ISS Assembly” in the Integrated Sensor Suite Installation Manual.

Console Location

Place the console in a location where the keyboard is easily accessible and the display is easy to read. For more accurate readings:

• Avoid placing the console in direct sunlight. This may cause erroneous inside tem-

perature and humidity readings and may damage the unit.

• Avoid placing the console near radiators or heating/air conditioning ducts.

• If you are mounting the console on a wall, choose an interior wall. Avoid exterior

walls that tend to heat up or cool down depending on the weather.

• If you have a wireless console, be aware of possible interference from cordless

phones or other devices. To prevent interference, maintain a distance of 10 feet between the Vantage Pro2 console and a cordless phone (handset and base).

• Avoid positioning a wireless console near large metallic appliances such as refrig-

erators, televisions, heaters, or air conditioners.

• The console antenna does not rotate in a complete circle. Avoid forcing the console

antenna when rotating it.

Table & Shelf Placement

The console kickstand can be set to three different angles allowing five different display angles.

1. Install the two round rubber feet on the bottom of the console. The rubber feet help prevent damage to furniture and surfaces.

Console Location

2. Lean the kickstand out by pulling on its top edge.

You’ll see the indentation for your finger at the top edge of the console.

3. Slide the catch to rest 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.

4. Install the two rubber channel feet on the kickstand.

If necessary, 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.

Console Location

Wall Mounting

The console mounts to the wall using two keyholes located on the back of the case. To mount the console on a wall:

1. Use a ruler to mark two mounting hole positions on the wall 8 inches (203 mm) apart.

8" (203mm)

Drill two 3/32" or 7/64" (2.4 to 2.8mm) holes 8" (203mm) apart for the #6 x 1" mounting screws.

This is a representation for the mounting hole positions. This template is not true to size.

If installing a cabled Vantage Pro2 console with sensor cable running inside the wall, mount the console over an empty switch box.

2. Use a drill and a 3/32 or 7/64''(2.5 mm) drill bit to drill two pilot holes for the screws.

3. Using a screwdriver, drive the two #6 x 1'' pan head self-threading screws into the wall. Leave at least 1/8'' (3 mm) between the wall and the heads of the screws.

4. If the kickstand has been pulled out from the case, push it back into its upright and locked position.

5. Guide the two keyholes on the back of the console over the two screws.

Alarm Mode

The Vantage Pro2 features more than 30 alarms that can be programmed to sound whenever a reading exceeds or drops below 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 is set at 65º F, the alarm sounds when the temperature rises to 65.0º F.

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 of two minutes if the console is battery-powered, but the icon continues to blink and the message stays in the ticker until you clear 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 “+” symbol appears 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 30ºF, the alarm condition begins when the wind chill drops to 30º and will continue until the wind chill rises above 30º.

Four Special Alarms

ET (Evapotranspiration)

ET is updated only once an hour, on the hour. If during a given hour the ET Value exceeds the alarm threshold, the ET alarm sounds at the end of that hour. This is true for daily, monthly, and yearly ET alarms. You must have the optional Solar Radiation Sensor to use this alarm. See “Evapotranspiration (ET)” on page 46. for a description of this variable.

Barometric Pressure

The Vantage Pro2 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 0.25 inches (6.35 mm) Hg, (8.5 mb, hPa); the alarm will sound if the rate of change (in either direction) exceeds the threshold you set. This alarm is updated every 15 minutes.

Time

Alarm Mode

The time alarm is a standard “alarm clock” alarm. It sounds for one minute at the set time. Make sure you choose AM or PM, if you’re in 12-hour mode.

UV Dose

The UV dose alarm sounds when the accumulated UV dose has exceeded the dose you set. The UV dose alarm does not arm unless the initial UV dose for the day has been reset. Once the UV dose alarm value is set, clear the accumulated UV dose. See “Clearing Weather Variables” on page 26.

For low readings, remove wind cups and check for friction sources. Check the anemometer location. Is it sheltered from the wind? See ISS manual for additional wind speed troubleshooting information.

The problem may be with the anemometer. Test anemometer by spinning wind cups. Check reed switch fields on diagnostic screen (see page 37) and call technical support.

Check calibration numbers for temperature. Dew point depends on temperature and outside humidity. Make sure they’re working.

Troubleshooting Reception Problems

While we have tested the Wireless Vantage Pro2 radio extensively, each site and each installation presents its own issues and challenges. Obstructions, particularly metallic ones, 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, before permanently mounting your ISS or other transmitter(s).

The console’s reception status displays at the lower right corner of the screen.

Console Diagnostic Mode

• An “X” flashes for every data packet received by the console.

• An “R” displays when the console is trying to re-establish a lost connection. The console tries for 10 minutes to re-establish a connection before going into L Mode.When no data packets have been received for 10 minutes, the console dashesout any missing sensor readings.

• An “L” displays when the signal is lost (and the console is “asleep.”) The console stays in this mode for 15 minutes until returned to “R” mode. To force the console into “R” mode (“wake up” the console), enter and exit Setup Mode.

Check Console Reception

Enter Setup mode by pressing and holding DONE, then pressing the - key at the same time. Wait a few minutes while the console lists all the stations transmitting within range (See “Screen 1: Active Transmitters” on page 10 for more information). If the console does not detect your transmitter, check the following:

• Adjust the console and ISS antennas so that they are in line of sight with each other.

• Reduce the distance between the ISS and the console.

• If the console is directly beneath the ISS, the antennas should be horizontal.

• Try distancing your console from your ISS, at least 10 feet apart.

• Change the Transmitter ID (on both the console and the ISS) to a number other than

Refer to the ISS Installation Manual or other station manual for instructions on how to check the station for potential transmission problems.

Console Diagnostic Mode

In addition to logging weather data, the console continuously monitors the station’s radio reception. You may find this information very helpful, especially when you are choosing locations for your console and ISS.

The Console Diagnostics Mode consists of two screens, the Statistical Diagnostic Screen and the Reception Diagnostic Screen. The Statistical Diagnostic screen applies for both cabled and wireless weather stations. The Reception Diagnostic screen applies only to wireless weather stations and is not accessible to a cabled weather station.

Note: Radio transmission data used by the diagnostic screens clears each day at midnight.

Diagnostic Screen Commands

• Press and hold TEMP, then press HUM to display the Statistical Diagnostic screen.

• Press the > key to display signal statistics for the next installed transmitter ID.

• Press 2ND and then press CHILL to toggle between the Statistical and Reception Diagnostic screens.

• A degree (

°) sign displays in right corner of value 1 of the Reception Diagnostic

screen (screen 2) to differentiate which screen is currently displayed.

• Press DONE to exit the diagnostic screen.

13. Background noise level. This refers to the undesirable signal level the console

hears while it is in the process of acquiring a signal from a station. The range displayed is from 5 to 60. When the noise level is high, try to move the console closer to the station to get a stronger signal. Small background noise level does not always guarantee good reception. The signal strength between the station and the console needs to be stronger than the background noise level in order for the console to receive clearly. If there are reception problems while a small background noise level is still being displayed, make sure the console is within reasonable range of the station.

If the console currently has acquired all the station signals it is set to receive, the background noise level displayed is the last noise level measurement taken before acquisition finished.

14. Current console battery voltage. Ignore this value if using the AC Adapter only to

power the console.

15. Repeater ID currently communicating with the console. If a repeater or group of

repeaters is used to relay station information to the console, the Repeater ID displayed is the repeater that the console is set to receive. If the console is not listening to repeaters, this section remains blank. Please see Application Note 25 available on the Davis Instruments Support web page for more information on using repeaters.

Note: The Repeater ID does not display in the ticker banner in firmware versions earlier than May 2005,

Console Firmware Versions

In some cases, the problem may be that your console firmware doesn’t support what you are trying to do. Use this command to determine the firmware revision level in your console. You can find more information on Vantage Pro2 console firmware versions and changes in the Weather Software Support section of our website. - for information.

Press and hold DONE then press the + key at the same time to display the console firmware version in the ticker at the bottom of the screen.

Console Maintenance

Changing Batteries

Use this procedure to change console batteries without losing any stored weather data or console configuration settings.

1. Plug in the AC adapter or, if the AC adapter is not present, enter Setup Mode by

pressing DONE and then the - key.

Note: If you cannot plug in the AC Adapter, entering Setup Mode makes sure the station isn’t writing

any data to memory when power is removed and avoids data loss.

2. Remove the battery cover located on the back of the console by pressing down on

the two latches at the top of the cover.

3. Place the console face down on a flat, firm surface.

4. Insert a fingertip between the two exposed batteries then press the middle battery

down toward the notch (toward the “hidden” battery). This will relieve tension on the first battery and allow you to remove it.

5. Remove the old batteries and install the new batteries.

6. Replace the battery cover and remove the AC power adapter, if used.

7. Check and set date and time if power was lost.

One Year Limited Warranty

For details on our warranty policy, please refer to the Maintenance, Service, and Repair Information brochure included with your station.

Appendix A Weather Data

Refer to this appendix to learn more about the weather variables that are measured, displayed, and logged by your Vantage Pro2 Station. Some weather variables require optional sensors. See “Optional Sensors & Transmitting Stations” starting on page 2.

Wind

The anemometer measures wind speed and direction, and is part of the Integrated Sensor Suite (ISS). The console calculates a 10-minute average 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 console. The last six 10-minute dominant 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 measure up to eight locations.

Apparent Temperatures

Vantage Pro2 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 warm air surrounding the body away. The faster the wind blows, the faster heat is carried away and the colder you feel. Wind has a warming effect at higher temperatures.

Note: Wind chill is not calculated above 92° F (33° C).

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 more saturated with water vapor) the apparent temperature “feels” higher than the actual air temperature, because perspiration evaporates more slowly.

Note: Heat Index is equal to the air temperature at or below 0° F (-18° C).

Temperature/Humidity/Sun/Wind (THSW) Index

The THSW Index uses humidity and temperature like for the Heat Index, but also includes the heating effects of sunshine and the cooling effects of wind (like wind chill) to calculate an apparent temperature of what it “feels” like out in the sun. The THSW Index requires a solar radiation sensor.

Humidity

Humidity itself simply refers to the amount of water vapor in the air. However, the total 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 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. 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 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 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, severe thunderstorms, and tornados.

You can also use dew point to predict the minimum overnight temperature. Provided no new fronts are expected overnight and the afternoon relative humidity is greater than or equal to 50%, the afternoon’s dew point gives you an idea of what minimum temperature to expect overnight, since the air can never get colder than the dew point. Dew point is equal to air temperature when humidity = 100%.

Rain

Vantage Pro2 incorporates a tipping-bucket rain collector in the ISS that measures

0.01'' for each tip of the bucket. A metric adapter can be installed to measure 0.2 mm

for each tip of the bucket.Your station logs rain data in the same units it is measured in and converts the logged totals into the selected display units (inches or millimeters) at

the time it is displayed. Converting at display time reduces possible compounded rounding errors over time.

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 or 0.2 mm.

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 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 Pro2 measures atmospheric pressure. When you enter your location’s altitude in Setup Mode, the Vantage Pro2 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.

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. meter (W/m

). Solar radiation requires the solar radiation sensor.

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, cataracts, and can suppress the immune system. The Vantage Pro2 helps 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 Pro2 displays UV readings in two scales: MEDs and UV Index.

Note: 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 Pro2 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 (Minimum Erythemal Dose) is 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.

UV Index

Vantage Pro2 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 in table A-3. 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 values displayed by the Vantage Pro2 are real-time measurements.

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 surfaces) with the amount of water vapor returned through transpiration (exhaling of moisture through plant stomata) to arrive at a total. Effectively, ET is the opposite of rainfall, and it is expressed in the same units of measure (inches, millimeters).

The Vantage Pro2 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 & Transmitting Stations” on page 2) 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. Leaf wetness requires an optional Leaf & Soil Moisture/Temperature Station and is only available for Wireless Vantage Pro2 Stations.

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. Soil Moisture requires an optional Leaf & Soil Moisture/Temperature Station or Soil Moisture Station and is only available for Wireless Vantage Pro2 Stations.

Time

The console has a built-in clock and calendar track the time and date. It automatically adjusts for daylight saving time in most of North America and Europe (and allows manual adjustment elsewhere) and for leap years, providing you have entered the correct year, latitude and longitude, and daylight saving settings in the Setup Mode.

Wireless Repeater Configuration

A Vantage Pro2 Wireless Repeater (#7626, #7627) or Long-Range Wireless Repeater (#7653, #7654) increase transmission distances or improve transmission quality between a station and a console. A repeater receives information transmitted from a Vantage Pro2 station and retransmits it to a console. Depending on transmission distance, one repeater or several repeaters can be used to collect and retransmit weather data.

All consoles communicating with repeaters must be set up with the correct Transmitter ID and Repeater ID before the console can correctly receive station information.

To set Repeater ID on the console:

1. Press DONE and the - keys to enter Setup Mode.

2. If Setup Mode has previously been completed, press DONE to display Screen 2: Configuring Transmitter IDs.

3. See “Screen 2: Configuring Transmitter IDs — Wireless Only” on page 10 for more information on configuring Transmitter IDs.

4. Press 2ND and then press WIND to enter Repeater Setup Mode and to select a Repeater ID. Pressing 2ND and WIND sets the console to receive the signal from a repeater instead of directly from a station. Once the console is in the repeater setup mode, subsequent pressing of WIND continue to cycle through the all the repeater IDs.

5. Press WIND repeatedly to cycle through all eight repeater IDs possible or to clear the repeater ID in the right hand corner. When no repeater ID is shown, the console is configured to listen directly to a station and not to a repeater.

In the example below, the console is set up to receive an ISS station on transmitter ID 1 from repeater A.

6. For each station using a repeater, select the station and turn on the repeater function and select the correct repeater ID.

7. Press DONE to continue to the other screens in the Setup Mode, or press and hold DONE to return to the Current Weather Mode.

Note: In console with the October 2005 version of firmware, the only way to exit Repeater

Setup mode is to press DONE to continue to the next setup screen.

Verifying Setup

To verify that you have successfully set up your console to receive a repeater in the console’s Current Weather Mode:

1. View the transmitter information displaying at the bottom of the console screen.

If the transmitter ID being repeated is displayed and an “X” flashes in the bottom right corner of the ticker tape, the transmitter is being repeated and received by the console successfully.

The repeater’s information also displays at the bottom of the console’s diagnostics screens.

Clearing Repeater ID

If a repeater ID is being displayed in Screen 2 and you are not using a repeater with the selected station, you must turn off the repeater function to receive station information successfully.

In Setup Screen 2:

Press 2ND and then press WIND repeatedly so that the console cycles through the list of repeater IDs (Repeaters A-H) until the section where the repeater ID was displayed is blank. Press DONE to continue to the next screen or press and hold DONE to return to the Current Weather Mode.
