Please read all instructions in this section before operating the TEROS 06 to ensure it
performs to its full potential.
pRECAUTIONS
METER sensors are built to the highest standards, but misuse, improper protection,
or improper installation may damage the sensor and possibly void the manufacturer’s
warranty. Before integrating TEROS 06 into a system, make sure to follow the recommended
installation instructions and have the proper protections in place to safeguard sensors from
damage. If installing sensors in a lightning-prone area with a grounded data logger, see the
application note
Lightning surge and grounding practices .
2.1 INSTALLATION
When selecting a site for installation, remember the soil adjacent to the sensor surface has
the strongest influence on the sensor reading.
Follow the steps listed in Table 1 to set up the TEROS 06 and start collecting data.
Table 1 Installation
Tools Needed
TEROS 06 auger
Dead blow hammer
pVC casing or flexible conduit (to protect cables)
Cable inserting tool (if using long flexible conduits)
Spade (to dig a slot for the cable)
Level (to check that auger is level as it is digging the hole for sensor)
preparation
Conduct System Check
Plug the sensor into the logger (
Section 2.3 ) to make sure the sensor
is functional.
Installation
Create Hole
Avoid interfering objects, such as roots or rocks.
Mark the required drilling depth (104 cm) on the TEROS 06 auger.
Drill a hole stepwise until the marker reaches the soil surface ( Section 2.3 ).
Avoid soil compaction by drilling with several steps (maximum drilling step
length = 30 cm).
ATTENTION: Minimize air gaps and soil compaction around the sensor. Air gaps around
the sensor will result in slow readings of soil temperature.
Dig a narrow trench 15 cm deep with a spade from the TEROS 06 installation
location to the data logger site to bury the sensor cable.
