OPERATION
2.3 CONNECTING TO A ZENTRA OR EM60 FAMILY DATA LOGGER
The ATMOS 41 works seamlessly with ZENTRA or EM60 data loggers. Plug the 3.5 mm stereo
plug connector into one of the six sensor ports.
Once the ATMOS 41 has been connected to a ZENTRA or EM60 data logger, configure the
logger port for the ATMOS 41, and set the measurement interval. Logger configuration may be
done using either ZENTRA Utility (desktop and mobile) or ZENTRA Cloud (for cell-enabled
ZENTRA data loggers).
To download ATMOS 41 data from a ZENTRA or EM60 logger, use ZENTRA Utility or
ZENTRA Cloud.
NOTE: The ATMOS 41 draws more current than most other METER sensors because it makes frequent measurements
of wind speed and precipitation. As a result, plugging multiple ATMOS 41 stations into a single ZENTRA or E
M 60 data
loggers may have significant impact on battery life. At times or in regions with plentiful sunshine, the solar
panel should provide ample charge and this should not be an issue. But, during the winter or periods of extended
heavy clouds, the solar panel may not provide enough charging current to keep the system running with multiple
ATMOS 41 units. METER recommends using only one ATMOS 41 per ZENTRA or E
M 60 data logger.
2.4 CONNECTING TO A NON-METER LOGGER
The ATMOS 41 weather station may be purchased for use with non-METER data loggers.
These 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 wiring.
The
ATMOS 41 Integrator’s Guide gives detailed instructions on connecting the weather
station to non-METER loggers. Visit https://www.metergroup.com/environment/products/

2.5 PIGTAIL END WIRING
Connect the weather station wires to the data logger as illustrated in Figure 2 , 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: Some early ATMOS 41 units may have the older Decagon wiring scheme where the power supply is white, the
digital out is red, and the bare wire is ground.
