OPERATION
2. OPERATION
Please read all instructions before operating the ATMOS41 to ensure it performs to its
full potential.
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 into a system, follow the recommended installation
instructions and have the proper protections in place to safeguard sensors from damage.
2.1 INSTALLATION
Follow the steps listed in Table 1 to set up the ATMOS41 and start collecting data.
Table 1 Installation
Tools Needed
Wrench 13 mm (1/2 in)
Mounting pole 31.8 to 50.8 mm (0.25 to 2.0 in) diameter
NOTE: Smaller mounts are compatible if washers are added to the V-bolt (not included).
United States standard pipe sizes that are compatible are 1.00-, 1.25-, and 1.50-in. Square
tubing with a width of 1.25 to 2.00 in or T-posts can also work as mounting options.
Preparation
Consider the Surroundings
Ensure that site selection is far from wind obstruction.
Make sure surrounding objects will not shade the solar radiation sensor.
Choose a site far from sources of high electromagnetic interference (EMI),
such as high-voltage power transmission lines. EMI sources adversely affect
ATMOS41 lightning and rainfall measurements.
Conduct System Check
Plug the weather station into the logger (Section 2.2).
Verify all sensors are functional and read within expected ranges.
Adjust Pole Height
Prepare the mounting pole to the appropriate height. Many installations
require the ATMOS41 to be mounted 2 m above ground, but mounting height
can be adjusted based on the specific application.
Mounting
Install on Mounting Pole
Use the V-bolt to mount the unit at the desired height. The V-bolt is compatible
with most meterological stands, poles, tripods, and other mounts.
Mount Toward True North
Orient the N engraved on the side of the instrument should be oriented to point
true north (not magnetic north). The ATMOS41 must be oriented correctly by
hand for accurate wind direction measurements.
