will use a default temperature of 75° F (24° C) to compensate the soil moisture
readings.

Finishing the Sensor Connections to the Station

1. Secure sensor cables within the cable clamps located next to the grommets. See

the above illustration.

2. Secure the cable clamps using the by screwing

them to the cable clamp mounts inside the hous-
ing near the grommets.

3. 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.

Locating Sensors

Be aware of the soil variations in your field or lawn. The lighter soils dry very
quickly, heavier soils more slowly. Both conditions must be considered.

Furrow or Flood Irrigation

• Sensors are usually placed about 2/3 of the way down the run, just ahead of the

tail or backup water. This is the area where water penetration is usually the poor-
est.

• In tree crops, place the sensors on the drier side of the tree exposed to the most

sun. In the Northern Hemisphere, this is typically the Southwest side of the tree,
which is exposed to the hot afternoon sun.
