9. Lay the Dart Template on the Test Spot. Drive the four (4) Darts into the soil through the holes in
the Template until the Dart shoulder is just even with, or slightly lower than, the soil surface. Then
connect it to the Soil Sensor.
10. Place the Soil Sensor Unit in the center of the Template with the Probe Pins pointing up. Using
the Red Cable, connect a Probe Pin to the nearest Dart, and with the Black Cable, connect the other
Probe Pin to the Dart on the opposite side of the circle. Let the Cables loop upward when connecting,
and keep them separated from one another. We'll call this first configuration “A-A”.
11. When using the Temperature Probe, drive a large nail 2 in. deep into the soil near the Test Spot.
Insert the Temperature Probe, and press down the soil around the probe shaft. (Note: The
temperature probe must be used when creating a Soil Model.)
12. Keep your hands away from the Cables, Darts, or Soil Sensor Unit, otherwise you may cause
errors. Press the EDG button to start testing. Testing will take approximately five (5) seconds.
13. Test Connection " B-B " will be performed with the Soil Darts that have not yet been used. This
will generate a measurement pattern that is at right angle to the first test. Connect the cables to the
yet unused Darts, and press the EDG button. There are now four (4) electrical soil measurements (2
for the A-A configuration, and 2 for the B-B configuration) recorded in EDG memory that will be
averaged into one final electrical signature of that test spot. The completion of the series of tests is
announced.
14. It is necessary to make physical determinations of the Wet Density, Dry Density, and Moisture
