SECTION 1 INTRODUCTION

Congratulations on your purchasing the WMR968 Cable Free

TM

Weather Station. An all-purpose easy-to-use system, the WMR968
lets you monitor the following weather elements:

- Air temperature

- Relative humidity

- Barometric pressure

- Wind speed and direction

- Rainfall
The WMR968 is also equipped with:

- Calendar clock with daily alarm

- Weather forecast within 32 to 48 km (20- to 30-mile) radius

- Weather alarms

- Memory for maximum and minimum readings

- Simple, touch-screen operation

- RS232 PC connection jack

-

backlight

STANDARD PACKAGE

The original WMR968 comes complete with the following:

- Main unit (WMR968)

- Anemometer (WGR968)

- Thermo-hygrometer (THGR968)

- Rain gauge (RGR968)

- Baro-thermo-hygrometer (BTHR968)

- 12V AC adapter

The thermo-hygrometer and rain gauge are powered by solar
transmitters STR928 while the anemometer is powered by solar
transmitter STR938.

The WMR968 can support up to seven different remote instruments.
You can also connect up to three optional thermo or thermo-hygro
sensors to the system.

Optional items include:

- Thermo-hygro sensor (THGR238)

- Thermo sensor (THR238)

Contact an authorized dealer for optional items.

SECTION 2 INSTALLATION

The WMR968 operates at 433MHz. No wire installation is required
among units.

The WMR968 has an effective range of 109 yards in an open area.
Position the units within the range and be sure the transmission
path is clear of interference and obstacles.

Note:The anemometer, thermo-hygrometer and rain gauge should
be installed outdoors and in locations that best measure the weather
elements the instruments are designed for. As for the baro-thermo­hygrometer, it must be installed indoors. If you have any optional
thermo or thermo-hygro sensors, they can be installed outdoors or
indoors.

THE ANEMOMETER

The anemometer measures wind speed and direction.

To install it,

1. Place the wind cup over the thinnest shaft on the anemometer’s
T-bar.

2. Tighten the screw on the base of the wind cup.

3. Align the red markings on the wind vane’s shaft.

4. With the aid of a compass, face the red marking south before
mounting the anemometer.

5. Mount the anemometer and its solar transmitter safely in place.

The wind speed and direction window on the main unit should read
180° if the main unit is installed.

THE THERMO-HYGROMETER

The thermo-hygrometer measures outdoor temperature and
humidity.

To install it:

Mount the thermo-hygrometer and its solar transmitter safely in
place.

THE RAIN GAUGE

The rain gauge measures the total amount and rate of rainfall.

To install it:

1. Open the cover of the rain collector.

2. Remove the fiber tape from around the bucket assemblies.

3. Mount the rain gauge and its solar transmitter safely in place.

4. Put drops of water on the cross at the base on the rain collector
to check the leveling.

5. Use metal ring to adjust the leveling of the rain collector if
necessary.

6. Close the cover of the rain collector.

THE SOLAR TRANSMITTERS

The solar transmitters make use of solar energy to power the
instruments they are connected to.

Note: It is recommended to insert two UM3 or “AA”-sized super
lithium batteries for weather condition under 0 °C (32 °F).

For the solar transmitters to function properly, make sure the solar
receptors on the transmitters are exposed to sunlight and the
connectors of the connection cable are securely plugged in.

THE BARO-THERMO-HYGROMETER

The baro-thermo-hygrometer measures the atmospheric pressure,
temperature and humidity.

The sensor uses four UM4 or “AAA”-sized batteries.

To install it,

1. Insert alkaline batteries accordingly.

2. Mount the unit where you want to monitor the readings. Or you
can make use of its table stand to place it on a flat surface.

THE MAIN UNIT

The main unit gives you all the readings and controls. It should be
placed indoors.

The main unit is powered up by the 12V AC adapter.

To install it,

1. Position the main unit and other units within effective range
(109 yards).

2. Insert four UM3 or “AA”-sized alkaline batteries for backup
purpose.

3. Mount the main unit safely in place. Or use its table stand to
place it on a flat surface.

4. Connect the AC power adapter to the main unit and a wall socket.

5. Press the [RESET] button on the main unit to initiate operation.

The main unit will start searching for signals for about four minutes.
Upon successful reception, the readings will be displayed. The
main unit will update the readings at regular intervals.

Note: That if the main unit is operating solely on battery power, the
EL backlight and RS232 connection will be disabled.

LOW-BATTERY WARNING

There are low-battery indicators [

] for the main unit, rain

gauge, baro-thermo-hygrometer, thermo-hygrometer and optional
remote thermo and thermo-hygro sensors. Replace the batteries
when the respective indicators light up.

Note: The readings collected from the thermo-hygrometer and any
optional remote thermo and thermo-hygro sensors share the same
display window. The “OUT” and remote channel will share the same
low-battery indicator. When the battery level of the thermo­hygrometer is low, the low-battery indicator will turn on. If it is one
of the optional remote sensors, the low-battery indicator will
blink. To locate the channel in question, press the window to scan
through all available devices. The low-battery indicator will stop
blinking if the battery level is low for that one.
