Welcome to

Anemometer for Vantage Pro2

(6410)

The anemometer measures and displays wind speed and direction. The data is used to calculate other wind-related information such as wind run, wind chill, and the temperature-humidity-sun-wind index. This anemometer can be used with any

Vantage Pro2-compatible system.

Assemble the Anemometer

Attach the Wind Vane

The wind direction has been calibrated in the factory so that the wind direction will be correct when the arm is installed pointing north and the vane is installed correctly.

1. Slide the wind vane onto the wind vane shaft. The shaft’s cross section is Dshaped to ensure that the anemometer is installed correctly.

2. Tighten the set screw in the wind vane with the Allen wrench.

Attach the Wind Cups

1. Push the wind cups up onto the anemometer’s stainless steel wind cup shaft.

2. Slide the wind cups up the shaft as far as possible.

3. Use the Allen wrench provided to tighten the set screw on the side of the wind cups.

4. The wind cups should drop slightly when you let go.

5. Ensure that the set screw is screwed in fully and very tight. Failure to do so will cause the anemometer to function improperly.

6. Spin the wind cups.

7. 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.

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

Attach the Anemometer Arm to the Base

1. Insert the anemometer arm into the base, sliding the cable through the notch in the base as shown in illustration.

2. Be sure to line up the small hole in the arm with the holes in the base.

3. Insert the machine screw through the holes in the base and arm.

IMPORTANT:

Make sure cable is secure in channel

4. Slide the tooth-lock washer and hex nut onto the machine screw. Tighten the hex nut while holding the screw with a Phillips head screwdriver to prevent it from turning.

5. Press the sensor cable firmly and completely into the zig-zagging channel in the base, starting from the arm and progressing downward to the bottom of the base.

Installing the Anemometer

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.

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 or Envoy Manual.

Anemometer Siting Guidelines

• Mount the anemometer so that the arm is aimed true north.

Note: If your anemometer cannot be mounted aiming true north, you will need to calibrate the wind direction on your console to display accurate wind directions. See your console user manual

• 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).

Note: For more detailed siting suggestions, see Application Note #30: Reporting Quality Observations to

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

Installing the Base on a Wooden Post or Surface

6

1. Use a drill with a 3/16" (5-mm) drill bit to make pilot holes in these locations.

2. Drive the 3" lag screws through the flat washers and the holes in the anemometer base and into the wood.

Installing the Anemometer on a Pole or Pipe

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

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

37.5" (0.95 m).

• With the supplied U-bolts, the anemometer can be mounted on a pole having an outside diameter ranging from 1

" (32 – 44mm).

• Larger U-bolts (not supplied) can be used to mount to a pole with a maximum outside diameter of 2

/

" (64mm).

• To mount on a smaller pole, obtain a U-bolt that fits the base openings but that has a shorter threaded section.

Mounting Base

1. Place the U-bolt around the pole so that its two ends extend through the holes in the mounting base. Loosely secure with the flat washers, lock washers and hex nuts.

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

3. Using an adjustable wrench or 7/16" wrench, tighten the hex nuts until the anemometer is firmly fastened on the pole.

Securing the Cable

To prevent fraying or cutting the anemometer cable where it is exposed to weather, secure it so it doesn’t whip about in the wind. Use cable clips or weather resistant cable ties to secure the cable. Place clips or ties approximately every 3 to 5 feet (1 to 1.6 m).

Securing cable

Note: Do not use metal staples to secure cables. Metal staples can cut the cables.

7

Optional: Anemometer Cable Length

Considerations

• Your anemometer includes a 40' (12 m) cable. This can be extended up to

540' (165 m) using optional extension cables purchased from Davis

Instruments.

• If most of the anemometer cable length is unused, the coiled cable length can be stowed once the anemometer has been installed on a site. Attaching the anemometer cable to the mounting pole using the supplied cable tie is the recommended option.

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

Maintenance

Your anemometer does not require any regular maintenance.

CAUTION: DO NOT attempt to lubricate the wind cup shaft and bearings or the wind vane shaft. Natural or synthetic lubricants will inhibit the normal operation of the anemometer.

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. 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.
