backlight

SECTION 2 INSTALLATION

The WMR918 operates at 433MHz. No wire installation is required among units.

The WMR918 has an effective range of 100 meters 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.

STANDARD PACKAGE

The original WMR918 comes complete with the following:

- Main unit (WMR918)

- Anemometer (WGR918)

- Thermo-hygrometer (THGR918)

- Rain gauge (PCR918)

- Baro-thermo-hygrometer (BTHR918)

- 12V AC adapter

The anemometer, thermo-hygrometer and rain gauge are powered by separate solar transmitters (STR918).

The WMR918 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 (THGR228/THGR238)

- Thermo sensor (THR228/THR238)

Contact an authorized dealer for optional items.

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.

1

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

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

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.

Water stay at position 1 - 4 means the gauge is not leveled

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

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

METAL RING

6. Close the cover of the rain collector.

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

THE SOLAR TRANSMITTERS

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

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

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 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 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.

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.

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.

2

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

(100 meters).

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

SECTION 3 OPERATION

THE MAIN UNIT

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 blanking if the battery level is low for that one.
