EasyAG TriSCAN Installation

The EasyAG TriSCAN is installed using the same technique as the standard EasyAG probes. The
information provided below is a summary only. Further information is provided in the EasyAG Installation
Guide Version 3.0. Users should read this Guide prior to installing the EasyAG probes.

Assembling the stabilization plate

The stabilization plate can be used on both flat ground and raised soil beds. There are two different types of
stabilization plate pins for this reason: short pins for flat ground and long ones for raised soil beds.

Fixing the stabilization plate on flat ground

1. Place the stabilization plate on the ground where the probe is to be situated. Insert the short

stabilization plate pins through the holes in the stabilization plate.

2. Drive the stabilization plate pins all the way into the ground using a sledgehammer. The stabilization

plate should be in firm contact with the soil without compressing it significantly.

3. Put the soil sampler polyguide in place.

Fixing the stabilization plate to a raised soil bed

1. Insert each of the four long stabilization plate pins into the holes in the stabilization plate and tighten

the wing nuts with light finger pressure. Place the assembled stabilization plate on the ground
directly above the required position of the probe.

2. Apply gentle pressure directly down onto the stabilization plate to force the pins into the ground.

Ensure that the stabilization plate pins remain parallel to one another.

3. Using a sledgehammer alternately beat the stabilization plate at the points provided to force it closer

to the ground. Do not beat continuously on any one side in advance of the other. The aim is to
achieve a situation where the pins are near parallel in the ground.

4. The stabilization plate should be firm to the ground without causing significant soil compression

5. Insert the soil sampler polyguide.

Preparing the hole

1. Insert the AMS soil sampler and force it downward in a single smooth action by hand until the

resistance becomes too great.

2. Using a sledgehammer, beat the AMS soil sampler into the ground until the bottom of the beating

head sits above the stabilization plate. Note: While it is preferable to go all the way in one insertion,
successful installation may be possible in heavier soils with 2 insertions. Ensure accurate blows are
made such that lateral deflection of the soil sampler is minimized.

3. Turn the AMS soil sampler one single complete rotation clockwise.

4. Carefully lift the AMS soil sampler directly out of the ground.

5. Remove the AMS soil sampler polyguide.

6. If the soil is dry, add a small quantity of water into the hole using a squirt bottle.

Assembling the EasyAG probe

1. Attach the cutting tip to the base of the probe with firm pressure. No glue is required.

2. Remove the lid of the top cap and extract the probe electronics. Place this safely to one side on a

clean, dry surface such as a tarpaulin.

Inserting the access tube

1. Insert the access tube into the stabilization plate and push it into the ground in a single gentle

movement as far as it will go. Do not cause undue inflection of the access tube, as this will destroy
the integrity of the installation.
