The WATERMARK Soil Moisture Sensor and the Multi-Purpose Temperature
Probe are for use with the Vantage Pro Wireless Leaf & Soil Moisture/Tempera-
ture Station, #6343. Please refer to your Wireless Leaf & Soil Moisture/Tempera-
ture Station Installation Manual for complete details on how to install and use
the sensors.
Note: These sensors are also compatible with the Soil Moisture/Temperature Station, #6361.
Connecting the Sensors
1. Run the sensor cables up through the grommets on the bottom of the station
housing.
2. Connect the temperature probes to the TEMP connectors.
3. Connect soil moisture probes to the SOIL connectors
4. Each matched temperature probe and soil moisture pair must use the match-
ing connectors. If a temperature probe is not used, the soil moisture reading
can be off as much as 1% for every 1
°
F (0.5
°
C) error in the soil temperature.
Note:
If no soil temperature probe is used, the console will use a default temperature of
75ºF (24ºC) to compensate the soil moisture sensor readings.
