3. Repack Soil and
Protect Cables

Secure and protect cables with

PVC casing or exible conduit
andbackll the trench or hole.

1. Insert Sensor

Auger or trench a hole to the
desired sensor depth. Insert the
sensor into the undisturbed soil.

When using the borehole
installation tool, load the

TEROS11/12 as shown above.

Lower the tool into the hole or

trench with the back of the tool

supported by the far wall. Pull on

the lever to activate the jack and

insert the sensor into hole wall.

2. Check Sensor Operation

Plug the sensor into the data logger
and use the SCAN function in the

software to do a quick check of
sensor operation before backlling.

Installation

TEROS 11/12 QUICK START

Preparation

Inspect and verify the sensor components (TEROS11 Soil Moisture
and Temperature or TEROS 12 Soil Moisture, Temperature, and

Electrical Conductivity). To validate sensor-to-sensor variability as

well as logger functionality, take a sensor measurement in air and
water. The TEROS 11/12 will read ~0.70 m3/m3 in water and a slightly

negative value in air.

NOTE: The sensors are optimized to read in soils, therefore the sensor will not read 100% in
pure liquid water.

Installation Tool

Proper installation of the sensors is critical for proper operation.
Refer to the TEROS 11/12 User Manual for details.

For easy installation, use the borehole installation tool. The

installation tool (shown below) is available for rent from METER

Group. Contact Customer Support for more information.

4. Plug Sensor In and

Congure Logger

Plug the sensor into the data

logger. Use data logger software

to apply appropriate settings to
the sensors plugged into each
data logger port.

ATTENTION

TEROS 11/12 requires the most current software and rmware

versions. Please make updates as necessary.

ZL6/EM60 rmware version 2.02 or higher

Em50 rmware version 2.29 or higher

ProCheck rmware version 1.70 or higher

What is soil moisture?

Soil moisture is a key variable in controlling the exchange of

water and heat energy between the land surface and the

atmosphere through evaporation and plant transpiration.
