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
TM
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 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.
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 vanes 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. 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.
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.
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.

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.
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 [ 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.
