Soil Moisture Sensor & Multi-Purpose Temperature

Probe Installation Instructions

For Wireless Leaf & Soil Moisture/Temperature Stations

The WATERMARK Soil Moisture Sensor and the Multi-Purpose Temperature

Probe are for use with the Vantage Pro2 Wireless Leaf & Soil Moisture/Temperature

Station, #6345. Please refer to your Wireless Leaf & Soil Moisture/Temperature

Station manual for more information on how to install and use the sensors.

Installation Procedures

Connecting the Sensors

•To extend the sensor cables, see “Extending Sensor Cables” on page 4.

•To use a temperature probe for temperature compensation of a soil moisture

sensor, install the sensor pair in corresponding connectors: 1 & 1, 2 & 2, 3 &

3, and 4 & 4.

•If no soil temperature probe is used, the station will use a default temp of

75°F (24°C) to compensate the soil moisture readings.

•If you are installing a temperature probe that is not providing temperature

compensation for a soil moisture reading, do not use a connector that matches

to any installed soil moisture sensor.

•If a soil moister / temperature sensor pair do not use matching connectors, the

soil moisture reading can be off as much as 1% for every 1

° °F (0.5C) error in

the soil temperature.

1.Run the sensor cables up through the grommets on the bottom of the station

housing.

2.Connect soil moisture probes to the SOIL connectors.

3.Connect the temperature probes to the TEMP connectors.
