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/m3in 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.
