Mounting
Install on Mounting Pole
The ATMOS 41 is fitted with a V-bolt, allowing it to be mounted on top of most
posts, poles, tripods, etc.
Mount Toward True North
If mounting the ATMOS 41 on a ferrous metal post or the compass-corrected
wind direction is
OFF, the ATMOS 41 must be oriented correctly for accurate
wind direction measurements. An
N engraved on the side of the instrument
should be oriented to point true north (not magnetic north).
NOTE: All ATMOS 41 units are shipped with the compass-corrected
wind direction set to OFF.
If mounting on a plastic post, the compass-corrected wind direction can be
turned
ON (uses an internal compass; can be turned ON using a ProCheck
Level the System
Use the bubble level underneath the ATMOS 41 or a ProCheck display to level
the weather station. The angle of the mounting pole may need to be adjusted
or shims added to the ATMOS 41 pole interface to achieve level. The ATMOS 41
must be within approximately ±2 degrees of dead level in both the X and Y
directions to accurately measure rainfall and solar radiation.
Secure the System
Use a wrench to tighten the bolts, securing the ATMOS 41 flat and tight against
the top of the stand.
Connecting
Plug Sensor into Data Acquisition System
• Connect the 3.5 mm plug into a ZENTRA or EM60 family of data loggers.
• Configure it to read the ATMOS 41 (refer to
).
Verify
• Use the
SCAN
function in the software to show a list of ATMOS 41 readings.
• Verify that these readings are within expected ranges.
Third Party Data Loggers
To connect to a non-METER data logger, see the
NOTE: ATMOS 41 will not work with legacy Decagon data loggers (EM50 Series and EM5B) because the ATMOS 41
outputs contain too many parameters.
