The WMR918 has an effective range of 100 meters. Position the units within the range
and be sure the transmission path is clear ofintert‘erenoe and obstacles.
Note the anemometer. therom—hygometer and rain guage should be installed outdoors
and in locations that best measure the weather elements the instruments are designed
for.
(Illustration: an artist's perception]
THE AN EMOMETER
The anemometer measures wind speed and direction It should be placed outdoors. To
install it‘
1. Mount the anemometer and its solar msmitter safely in place. Be sure the
