4. Place the wind cup over the thinnest shaft on the anemometer’s
T-bar.
5. Tighten the screw on the base of the wind cup.
6. Align the red markings on the wind vane’s shaft.
7. With the aid of a compass, face the red marking south before
mounting the anemometer.
8. 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.
9. Press [RESET] of STR938 after installation.
THE THERMO-HYGROMETER
The thermo-hygrometer measures outdoor temperature and humidity.
It uses two (2) UM-4 or “AAA” size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
2. Insert the batteries strictly according to the polarities shown
therein.
3. Replace the battery compartment door and secure its screws.
4. Press the [RESET] button.
THE RAIN GAUGE
The rain gauge measures the total amount and rate of rainfall.
To install it:
1. Unscrew the solar transmitter STR928N.
2. Plug in the connector of PCR918N into the solar transmitter as
shown.
3. Secure the screws again.
4. Open the cover of the rain collector.
5. Remove the fiber tape from around the bucket assemblies.
6. Mount the rain gauge and its solar transmitter safely in place.
7. Put drops of water on the cross at the base on the rain collector
to check the leveling.
8. Use metal ring to adjust the leveling of the rain collector if
necessary.
9. Close the cover of the rain collector.
10. Press [RESET] of STR928N after installation.
THE SOLAR TRANSMITTERS
The solar transmitters make use of solar energy to power the
instruments they are connected to. Two pieces of UM3 or "AA" -
sized batteries are needed as back-up power.
Note: It is recommended 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.
