Page 3: Introduction
TEROS 06 measures soil temperature at specified depths following World Meteorological Organization (WMO) recommendations. TEROS 06 is designed for measurements in the field, in lysimeters, and in water bodies. The small diameter of 20 mm minimizes soil disturbance and the fiberglass reinforced plastic... -
Page 4: Operation
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 Installation length = 30 cm). - Page 5 TEROS 06 Table 1 Installation (continued) NOTE: Burying the sensor cable will prevent thermal heat flux through the sensor cable into the TEROS 06. Otherwise solar radiation may heat up the cable and may affect reported temperature values. Insert Sensor Gently insert the probe into the borehole until the shaft end is flush with the soil surface.

2.3 CONNECTING The TEROS 06 works seamlessly with METER data loggers. The TEROS 06 can also be used with other data loggers, such as those from Campbell Scientific, Inc. For extensive directions on how to integrate the sensors into third-party loggers, refer to the TEROS 06 Integrator... -

Figure 3 4-pin M12 plug connector used with non-METER loggers 2.3.1 CONNECT TO METER DATA LOGGER The TEROS 06 works most efficiently with METER ZENTRA series data loggers. Check the METER download webpage (metergroup.com/downloads) for the most recent data logger firmware. Logger configuration may be done using either ZENTRA Utility (desktop and mobile application) or ZENTRA Cloud (web-based application for cell-enabled data loggers). -

SDI-12, tensioLINK serial, or Modbus RTU communications protocol. If the TEROS 06 cable being used with a non-METER data logger has a standard stereo plug connector and needs to be connected to a non-METER data logger, use one of the following two options. - Page 9 TEROS 06 Power (brown) Ground (bare) Digital communication (orange) Figure 4 pigtail wiring Digital Power communication Ground (brown) (orange) (bare) Excitation Digital Ground Data Logger Figure 5 Wiring diagram NOTE: The acceptable range of excitation voltages is from 3.9 to 28.0 VDC. To read the TEROS 06 with Campbell Scientific data loggers, power the sensors off a 12-V port or switched 12-V port.

Page 10: Communication
The SDI-12 protocol requires that all sensors have a unique address. If the TEROS 06 is being used with a non-METER logger using SDI-12 protocol on a bus, use the METER ZSC and the METER ZENTRA Utility Mobile app to change the sensor SDI-12 address. See the individual sensor integrator guide for more information about the SDI-12 protocol in the sensors. -

TEROS 06 2.5 REMOVING THE SENSOR To remove the sensor from the soil, pull gently on the sensor shaft until the sensor is out of the soil. WARNING: Do not pull by the cable! Doing so may break internal connections and make the sensor unusable. -

TEROS 06 COMpLIANCE Manufactured under ISO 9001:2015 EM ISO/IEC 17050:2010 (CE Mark) 3.2 COMpONENTS The TEROS 06 measures soil temperature in six defined depths of 5 cm, 10 cm, 20 cm, 30 cm, 50 cm, and 100 cm. At every measuring depth, the sensor rod is equipped with a 1-cm high stainless steel ring, and the digital sensor is mounted at the inner surface of the stainless steel ring. -
