7. Press the Search button (the magnifying glass) on the
RX3000 Station to stop searching for motes.
Measurements will be recorded at the logging interval specified
in HOBOlink, transmitted to the RX3000 Station, and uploaded
to HOBOlink at the next connection interval (readout). Use
HOBOlink to monitor mote status and health. If a mote is
temporarily offline, any logged data is saved until it is back
online. In addition, if a mote is offline for 30 minutes, the
RX3000 Station will automatically connect to HOBOlink and
report the mote as missing. Once the mote is back online, any
logged data will be uploaded the next time the RX3000 station
connects to HOBOlink.
See the HOBOlink Help for details on how to change the logging
and connection intervals, view data, check mote status, add the
mote to a map, and more.
Assembling the Sensor
Attaching the Wind Vane
The wind direction has been calibrated in the factory so that
the wind direction will be correct when the arm is installed
pointing north and the vane is installed correctly.
1. Slide the wind vane onto the wind vane shaft. The shaft's
cross-section is D-shaped to ensure that the anemometer is
installed correctly.
2. Tighten the set screw in the wind vane with the Allen
wrench.
Attaching the Wind Cups
1. Push the wind cups onto the anemometer's stainless steel
wind cup shaft.
2. Slide the wind cups up the shaft as far as possible.

3. Use the Allen wrench provided to tighten the set screw on
the side of the wind cups. The wind cups should drop
slightly when you let go.
4. Ensure the set screw is screwed in fully and very tight.
Failure to do so will cause the anemometer to function
improperly.
5. Spin the wind cups; they should spin freely. If they do not
spin freely, take them off and repeat these steps
Attaching the Anemometer Arm to the Base
1. Insert the anemometer arm into the base, sliding the cable
through the notch in the base as shown below. Be sure to
line up the small hole in the arm with the holes in the base.
2. Insert the machine screw through the holes in the base and
arm.
3. Slide the tooth-lock washer and hex nut onto the machine
screw. Tighten the hex nut while holding the screw with a
Phillips head screwdriver to prevent it from turning.
4. Press the sensor cable firmly and completely into the zig-
zagging channel in the base, starting from the arm and
progressing downward to the bottom of the base.
Deployment and Mounting
Mounting and Positioning the Mote
• Use cable ties to mount the mote via the holes on the
mounting tabs.
• Avoid mounting the mote near metal, which can cause
interference with the signal.
• Position the mote towards the sun, making sure the solar
panel is oriented so that it receives optimal sunlight
throughout each season. I It may be necessary to
periodically adjust the mote position as the path of the
sunlight changes throughout the year or if tree and leaf
growth alters the amount of sunlight reaching the solar
panel.
• Make sure the mote door is closed, with both latches fully
locked to ensure a watertight seal.
