ATMOS 41
2.2 CONNECTING THE ATMOS 41
The ATMOS 41 Compact Weather Station works most efficiently with a ZENTRA or EM60
data loggers. This system will not work with legacy data loggers (Decagon EM5, EM5
B ,
EM50, EM50R, EM50G) because the ATMOS 41 has too many output parameters (previously
limited to three). The standard station with a 3.5 mm stereo connector (
Figure 1 ) connects to
and is configured with a ZENTRA or EM60 data logger.

The ATMOS 41 is also compatible with third party loggers and may be purchased with
stripped and tinned wires (pigtail) for terminal connections. For extensive directions on
how to integrate the weather station into third-party loggers, visit

ATMOS 41 Integrator‘s Guide .
The ATMOS 41 comes standard with a 5-m cable. It may be purchased with custom cable
lengths for an additional fee (on a per-meter fee basis). METER has successfully tested
digital communication on cable lengths up to 1,000 m (3,200 ft). This option eliminates the
need for splicing the cable (a possible failure point). However, the maximum recommended
length is 75 m.
2.2.1 SAFETY 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 ATMOS 41 or other METER sensors into a system, make sure to follow
the recommended installation instructions and have the proper protections in place to
safeguard sensors from damage.
2.2.2 CABLE PROBLEMS
Improperly protected cables can lead to severed cables or disconnected sensors. Cabling
issues can be caused by many factors, including rodent damage, driving over sensor cables,
tripping over the cable, not leaving enough cable slack during installation, or poor sensor
wiring connections. To relieve strain on the connections and prevent loose cabling from being
inadvertently snagged, gather and secure the cable travelling between the ATMOS 41 and the
data acquisition device to the mounting mast in one or more places. Install cables in conduit
or plastic cladding when near the ground to avoid rodent damage. Tie excess cable to the
data logger mast to ensure cable weight does not cause sensor to unplug.
