OWERING

SSEMBLING

The Weather Wizard III is a precision instrument, designed to give extremely accurate readings. As with any precision instr ument, car e must be used during assembly. These instructions detail how to assemble the stations with a minimum of time and effort.

THE

The Weather Wizard III is powered by 9- to 12-volt DC (direct current). In North America, the power adapter included with your unit converts 120-volt, 60-Hz AC (alternating current) to 9-volt DC, allowing you to run the unit on ordinary household current. You may also run the Weather Wizard III on the 12-volt DC power supplied by a car, boat, or RV battery by using the optional Car/Boat/RV Lighter Cord.

If you are outside North America and in a location where the power supply is not equivalent to the North American standard (120-volt, 60-Hz), check to see if your local dealer has supplied a power adapter that is appropriate for your power supply before you connect the power adapter to the console. If not, you must use a power converter/transformer or the appropriate power adapter (9volt, 2.5-mm female plug).

In any case, we recommend that you also install a 9-volt alkaline battery as a backup power supply. In the event of a power outage, the battery will power the station. Not only will this prevent the loss of stored data in the console, but will also allow you to continue observing weather conditions during the power outage.

New alkaline batteries will power the Weather Wizard III for 24 - 48 hours. For maximum security, keep the battery backup fresh. You should replace batteries any time the unit has operated on battery power for more than 18 hours. To prevent loss of data when replacing batteries, make sure the unit is receiving power from the adapter before changing batteries.

Note: We do not recommend the use of Ni-Cad batteries. Ni-Cad batteries carry less power than alkaline

batteries, and they will not be recharged by the station. In the event of a power outage, Ni-Cad batteries will be able to power the station for a shorter period of time than alkaline batteries will.

To Connect the Power Adapter to the Console

1. Remove the mounting base from the console.

Push down on the large tab behind the display until it will easily slide out from the notch. Then lift the mounting base so the two smaller tabs behind the keyboard slide free. Place the mounting base aside until you mount the console (see “Displaying the Console” on page 14).

2. Slide the power adapter plug into the jack marked POWER underneath the console.

3. Plug the other end of the power adapter into an appropriate power outlet or, preferably, into a computer-grade surge protector.

It is highly recommended that you plug the power adapter into a computer-grade surge protector, especially in lightning-prone areas.

should run through a brief self-test procedure. All of the display segments appear, and the console beeps twice within 10 seconds (3 times within 20 seconds if WeatherLink is installed) to indicate everything is working properly.

After the second beep (or the third beep with WeatherLink), the compass rose and the time (reading 12:00 a.m.) appear on the display.

To Install the Battery Backup Power Supply

Before you install the backup battery, make sure AC power is connected and the console is completely powered up. Installing the battery ﬁrst can cause the console to lock up.

Once the console is powered up, install the backup battery as shown below.

ONNECTING

The junction box is the connecting point between the external sensors and the console. Information from the sensors comes into the junction box. The junction box then relays that information to the console where it is processed and displayed.

To Connect the Console and Junction Box

1. Plug one end of the 8-foot (2.4-meter) long junction box cable into the jack labeled JUNCTION BOX underneath the console.

2. Plug the other end of the cable into the jack marked CONSOLE on the junction box.

Assembling the Anemometer

SSEMBLING

THE

NEMOMETER

To assemble the anemometer you will need the following: anemometer arm (with cable), anemometer base, wind cups, drip rings, allen wrench, 4-40 x 1 1/8-inch pan head screw, #4 ﬂat washer, #4 lock washer, and 4-40 hex nut.

Avoid lubricating the wind cup shaft and bearings or the wind vane shaft. Natural or synthetic lubricant affects the normal operation of the anemometer by reducing the component's efﬁciency. It also may attract insects which can jam moving parts.

Note: Do NOT attach the wind vane at this time. Wait until you have installed the anemometer (see

page 11) before attaching wind vane.

To Attach the Anemometer Arm to the Anemometer Base

1. Insert the anemometer arm into the anemometer base, sliding cable through the slot

in the base as shown. Line up the small hole in the arm with the holes in the base.

2. Insert the 4-40 screw into one of the holes in the base and through the arm.

The screw should slide easily through the holes.

3. Secure as shown below.

To Attach the Drip Rings to the Wind Vane and Anemometer Arm

The drip rings provide excellent protection against icing of the wind vane and wind cups. If you choose not to install them, however, the anemometer will function normally in non-icy conditions.

1. Apply adhesive liberally to the inside of one of the drip rings and install on the wind

vane as shown below.

Make sure the lower edge of the drip ring is approximately parallel to the bottom of the wind vane.

2. Apply adhesive liberally to the inside of the other drip ring and install on the WIND CUP END OF THE ANEMOMETER CONTROL HEAD as shown below.

The wind cup end of the control head is the smaller of the two stainless steel shafts.

Note: When attaching drip ring, make sure the lower edge of the ring is aligned with the lower edge of

the control head. If the drip ring extends below the lower edge of the control head, the wind cups will not have room to slide on.

3. After the cement has properly cured (according to the cement’s direction), follow the instructions below to attach the wind vane and wind cups to the anemometer.

To Attach the Wind Cups to the Anemometer Arm

1. Push the wind cups onto the smaller of the two stainless steel shafts at the end of the arm.

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

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

Note that when you let go of the wind cups, they should drop slightly.

4. Spin the wind cups. If they do not spin freely, loosen the set screw and lower the cups slightly. Repeat until the wind cups spin freely.

ESTING

Before continuing with the installation , test the station in your living room or

workshop. If you have purchased the optional rain collector or additional sensors, now is the time to assemble and test these using the appropriate manual. Consult the Troubleshooting Guide on page 32, or the guides in the respective manuals, if you experience any difﬁculty.

Note: You should test each external sensor without extension cables ﬁrst, and then repeat the test with

extension cables. In this way, you can be reasonably sure whether any problems are the fault of the extension cables or the external sensor itself.

THE

Before you install the anemometer, make sure that the wind speed and wind direction sensors are functioning correctly.

1. Insert the cable plug at the end of the anemometer cable into the jack marked WIND

on the junction box.

2. Test your assembly by spinning the wind cups.

You should get a speed reading other than 0 on the compass rose in the console display. If you do not, loosen the set screw and move the wind cups slightly up or down on the shaft until you get a reading other than 0. Once you are getting a reading, use the allen wrench provided to tighten the set screw on the side of the wind cups. Do not over-tighten.

3. Turn the wind direction shaft (the larger of the two stainless steel shafts on the con-

trol head) with your ﬁngers.

Check that the direction readings change on the compass rose in the console display.

NSTALLING

Make sure you have thoroughly tested the station before installing it. Then, decide where you will place each component—the junction box, the console, and all external sensors. Pay close attention to the suggestions given in the sections dealing with the individual components, as well as the following general suggestions:

• The junction box cable must be able to reach the console.

If you want to place the junction box and console more than 8 feet (2.4 m) apart, you will need a longer junction box cable (see page 2).

• The cable coming from each external sensor must be long enough to reach the junction box.

To prevent wind damage, leave some slack to allow the cables to be secured to available surfaces. If the sensors are placed farther away than their allotted cable lengths allow, use extension cables (see page 2).

NSTALLING THE ANEMOMETER

Most people install the anemometer on the roofs of their houses, where wind ﬂow is unobstructed by trees and nearby buildings. For the most representative readings, the anemometer should be mounted at least 4 feet (1.2 m) above the roof line. You can do this by mounting the anemometer on your television antenna or on a raised piece of wood or metal pipe.

We have included the hardware most commonly needed for the installation of the anemometer. The hardware you use depends upon where you install your unit. You may need to adapt or purchase additional hardware to ﬁt your individual requirements.

THE

TATION

To Install the Anemometer

1. Disconnect the anemometer cable from the junction box.

2. Wrap the WIND cable labels around each end of the cable.

3. Mount the anemometer according to the following instructions. As you do so, use a carpenter's level to make sure the anemometer base is mounted vertically.

WOODEN POST OR SURFACE

1. Locate a suitable mounting surface for the anemometer base. The mounting surface should be at least as wide as the anemometer base and level.

2. Hold the anemometer base against the wood surface and use a pencil to mark the location of the four holes on the base.

3. Use an electric drill with a 3/16 inch (4.8-mm) drill bit to make pilot holes in these locations.

4. Drive the four lag screws through the holes in the anemometer base and into the wood.

2. Hold the anemometer base against the pipe and insert the two

U-bolts through the back of the base so that the U-bolts wrap around the pipe.

3. Place a 1/4-inch washer and a 1/4-20 hex nut over each end of

the U-bolts. Use a wrench to tighten the hex nuts.

METAL MAST OR PIPE - OUTSIDE DIAMETER GREATER THAN 1 1/4 INCHES (32 MM)

1. Obtain two stainless steel hose clamps large enough to ﬁt

around the mast or pipe and the anemometer base. These can be purchased at your local hardware store.

2. Make sure that the metal mast or pipe is properly grounded. If

you are not sure, consult a qualiﬁed professional.

3. Hold the anemometer base against the pipe and fasten the hose

clamps over the anemometer base and around the metal mast or pipe.

To Attach the Wind Vane

To mount the wind vane, you will need to look at the console display. You may wish to have a friend or family member on the ground do this for you. Or, you may wish to bring the console and junction box onto the roof with you.

1. After installing the anemometer, re-insert the plug at the end of the anemometer

cable into the jack marked WIND on the junction box

2. Press WIND on the console until a wind direction reading and the word DIRECTION

appear on the display.

3. Use a compass or local area map to determine which direction (N, S, E, W, NE, etc.)

the anemometer arm is pointing.

4. Use the wind direction chart to ﬁnd the

0° N

degree reading which corresponds to that direction.

5. Slowly turn the wind direction shaft with your

ﬁngers. Stop turning when the console display reaches the degree reading obtained in
