LEAF WETNESS SENSOR

INSTALLATION MANUAL

The leaf wetness sensor enables the Vantage Pro2™ Wireless Leaf & Soil Mois-

ture /Temperature Station (#6345) to detect the presence of surface moisture on

foliage and calculate the duration of wetness. When moisture is present, the

sensor detects an electrical resistance change between the gold-plated ele-

ments of the grid. This is displayed by the Vantage Pro2 console as a value

between 0 (dry) and 15 (wet). With WeatherLink

software and the Agricul-

tural/Turf Management Module (#6511), you may select your own wetness

threshold; the software will then calculate leaf-wet hours.

I NSTALLING THE S ENSOR Connecting Leaf Wetness Sensors 1. Run the sensor cables up through the grommets on the bottom of the station housing. 2. Insert the sensor cable modular plug into the Leaf 1 or Leaf 2 modular connector. Grommets Leaf Wetness Sensor Cables Run Through Grommets Connecting Leaf Wetness Sensors Finishing the Sensor Connections 1. Secure sensor cables to the cable tie mounts located next to the grommets.

T ESTING THE S ENSOR You may test the sensor before or after you mount it. 1. Connect the sensor. 2. Make sure you are getting a leaf wetness reading on the console. Consult the Vantage Pro2 Console manual for instructions. 3. Drop or spray water onto the sensor and make sure the reading changes. M OUNTING THE S ENSOR Mounting the Sensor On a Wooden Surface Use the #8 wood screws to mount the sensor on a wooden surface as shown.

T ECHNICAL S UPPORT Before calling Technical Support (1-510-732-7814), carefully check all cable connections from the sensor to the console. Cable connections account for a large portion of the potential problems. Connections should be firmly seated in the jacks and plugged in straight. If you think a connection may be faulty, try jiggling the cable while looking at the display. If a reading appears intermittently on the display as you jiggle the cable, the connection is faulty.
