Rules For Using The Sensors - Davis Instruments Wireless Leaf & Soil Moisture/Temperature Station Installation Manual

2. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.
3. Using an adjustable wrench or 7/16" wrench, tighten the nuts.
4. Place the second U-bolt around the pole and through the two holes at the bottom
of the shelter.
5. Put a flat washer, a lock washer, and a hex nut on each bolt end, and tighten the
hex nuts.
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.
6. To prevent fraying or cutting of cables, secure
them so they will not whip about in the wind.
Secure a cable to a metal pole by wrapping elec-
trical tape around them both. Make sure cables
are secure by placing clips or ties approximately
every 3 – 5' (1 – 1.6 m).
Note: Do not use metal staples or a staple gun to secure cables. Metal staples — especially when
installed with a staple gun — have a tendency to cut the cables.
Rules for Using Leaf, Soil and Temperature Sensors
The following station and sensor configurations are supported by the Leaf/Soil Sta-
tion:
Station Type in
Console
Configuration
LEAF/SOIL Station
LEAF Station
SOIL Station
• A station configured as a LEAF station in the console will support two leaf wet-
ness sensors and two leaf temperature probes.
• Leaf temperature probes can be used as you wish to measure air, water, or soil
temperature. Leaf temperature does not affect leaf wetness readings.
• A station configured as a SOIL station in the console will support four soil mois-
ture sensors and four soil temperature probes.
• If you have installed any soil moisture sensors (SOIL 1, SOIL 2, SOIL 3, SOIL
4), the corresponding temperature probes (TEMP 1 for SOIL 1, etc.) will be used
to provide temperature compensation for the soil moisture sensor readings.
• If you want to use a temperature sensor for something besides compensation for a
soil moisture sensor, then you cannot use the corresponding soil moisture sensor.
