User's Manual

1. Using a 1.5” putty knife or something similar, create a vertical slit

in the soil, so the center of the slit is 1.5” to 1.75” below the top of

the soil and within the root zone of the plant.

2. Take some dirt from the hole and perform a ﬁeld test to identify

the soil’s physical properties which will be used later for setting

the zone Wetness Settings (Field test instructions can be found in

in Appendix B).

3. Replace the tine sleeve on the sensor and remove to initiate rapid

broadcast mode.

4. Insert the sensor blade into the slit you created without wiggling

or applying any side-to-side pressure on the sensor blade.

5. Place the whisker, loop side down so that the top is out of the

ground at a level that is close to the length of the grass or where

it can be covered by a thin layer of mulch, (If sensor is located in

a planting bed).

6. The whisker should be placed at the side of the sensor body (not

sensor blade) away from the base station. (See ﬁgure on pre-

ceeding page) This will allow for easy location of the sensor since

you know which way it is orientated in relation to the Base Sta-

tion and whisker marker.

Do not be overly concerned about the

height of the whisker marker; it can be cut by the lawn mower

without damage.

IMPORTANT NOTE: RECORD LOCATION OF SENSOR

Once all sensors communicate from their buried positions, take two measurements (from permanent structures like

sprinkler heads, valve boxes, light posts and walk ways) to triangulate their position so that they can be found later.

Record this information on the Sensor Location Reference Guide which is on the back side of the Wire Reference

Guide. Avoid structures that are less permanent like trees and plants. Be sure to record the NWA for each sensor in

the Zone column as well.

Whiskers will provide visual locations, but are not a permanent ﬁxture and may be removed accidentally, so measure-

ments are important.
