4.Install all components, then connect all related components.

5.Connect the anemometer, outdoor thermo/hygro sensor and rain gauge to their individual solar transmitters to receive the weather element data. Each solar transmitter needs two AA batteries (not supplied) for backup power.

Notes:

•Install the anemometer, outdoor thermo/ hygro sensor, and rain gauge outdoors in a location that provides the best mea- surement for the weather elements the instruments are designed for.

•To reduce interference, do not install individual solar transmitters closer than 3.28 feet (1 meter) to each other.

•We recommend that you use lithium bat- teries in any component that could be exposed to temperatures between –4°F (–20° C) and –58°F (–50° C) or colder.

•If you are installing more than one weather station in the same area, wait at least 30 minutes between the installa- tions.

Estimating the Mounting

Distances

To help you find the right location for each weather station component, follow the tips listed in “Selecting a Location” on Page 11 that precede the mounting instructions for that component.

Before you mount any of the components, we recommend you select a general mounting location for each component first, then measure the distance between the locations for components that you will be connecting to each other to be sure the selected locations are close enough together.

For the best reception, mount the solar transmitters no more than about 328 ft (100 m)

from the monitor. Obstacles between the solar transmitters and the monitor might reduce the effective range.

The maximum length of serial cable (not sup- plied) required to connect the monitor’s RS- 232 jack to a PC is 10 feet, so the monitor must be located indoors within 10 feet of your PC.

CALIBRATING THE

ANEMOMETER

Before you mount the anemometer at the selected mounting location, follow these steps to calibrate it with the monitor, so the monitor properly measures wind speed and direction.

Important: You must be able to view the monitor while you assemble and calibrate the anemometer. You must temporarily install the monitor and connect AC power to it. Be sure to follow these steps before you install the anemometer at its mounting location.

Assembling the Anemometer

1.Place the wind cup over the thin shaft on the anemometer’s bar, use a small Phil- lips screwdriver to tighten the screw on the base of the wind cup, then insert one of the supplied rubber screw covers into the screw’s hole to protect the screw from corrosion.

2.Use a Phillips screwdriver to loosen the screws on the cover of the anemome- ter’s solar transmitter, then remove the cover. The anemometer’s cable and
