TEROS 11/12
TEROS 11/12 data can be downloaded from METER data loggers using either ZENTRA
Utility or ZENTRA Cloud. Refer to the logger user manual for more information about these
programs.
2.2.2 CONNECT TO NON-METER LOGGER
The TEROS 11/12 can be purchased for use with non-METER (third-party) data loggers. Refer
to the third-party logger manual for details on logger communications, power, and ground
ports. The
also provides detailed instructions on connecting
sensors to non-METER loggers.
TEROS 11/12 sensors can be ordered with stripped and tinned (pigtail) connecting wires for
use with screw terminals. Refer to the third-party logger manual for wiring details.
Connect the TEROS 11/12 wires to the data logger illustrated in
, with
the power supply wire (brown) connected to the excitation, the digital out wire (orange) to a
digital input, and the bare ground wire to ground.

NOTE: The acceptable range of excitation voltages is from 4 to 15 VDC. To read TEROS 11/12 sensors with Campbell
Scientific, Inc. data loggers, power the sensors from a switched 12-V port or a 12-V port if using a multiplexer.
If the TEROS 11/12 cable has a standard stereo plug connector and needs to be connected to
a non-METER data logger, please use one of the following two options.
