2.2.2 CONNECT TO A NON-METER LOGGER
The TEROS 10 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. METER has some sample programs for third-party logger setup (see the METER
website).
TEROS 10 sensors typically come configured with stripped and tinned (pigtail) lead wires for
use with screw terminals. Refer to the third-party logger manual for details on wriring.
Connect the TEROS 10 wires to the data logger as illustrated in
, with the supply wire
(brown) connected to the excitation, the analog out wire (orange) to an analog input, and the
bare ground wire to ground.

NOTE: Some older adapter cables have the older Decagon wiring scheme where the power supply is white, the digital
out is red, and the bare wire is ground.

NOTE: The acceptable range of excitation voltages is from 3.0 to 15.0 VDC. To read TEROS 10 sensors with Campbell
Scientific, Inc. data loggers, power the sensors from a switched 12 V port.
