The anemometer measures wind speed and direction. The Anemometer is a part of the Cable Free Weather Station (WMR112A). If you want to see readings for the wind speed, wind direction and wind chill temperature you need to own a WMR112A main display unit. The anemometer is powered by solar transmitter STR938 that is included in the package. Press [RESET] of STR938 after installation and secure the screws again mount the anemometer and its solar transmitter safely in place. SECTION 2 To install it, INSTALLATION The wind speed and direction window on the main unit should read 180° if the main unit is installed.

To display the average wind speed, press the window till the "AVERAGE" icon is displayed. Rotate the wind vane on the T-Bar until 180o is displayed on the main unit LCD screen in the "Bearing" display window segment...
