Onset Davis S-WCF-M003 Quick Start

Davis® Wind Speed & Direction Smart Sensor (S-WCF-M003) Quick Start
Connecting to a Station
1. Stop the station if it is logging
2. Plug the smart sensor jack into an open smart sensor port on the station.
3. Start logging. See the station manual at www.onsetcomp.com/support/manuals for details on operating stations with smart sensors.
Assembling the Smart Sensor
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. 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.
2. Tighten the set screw in the wind vane with the Allen wrench.
3. Push the wind cups onto the anemometer's stainless steel
wind cup shaft.
4. Slide the wind cups up the shaft as far as possible.
5. 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.
6. Ensure the set screw is screwed in fully and very tight. Failure
to do so will cause the anemometer to function improperly.
7. Spin the wind cups; they should spin freely. If they do not spin freely, take them off and repeat these steps.
8. 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.
9. Insert the machine screw through the holes in
the base and arm.
10. 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.
11. 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.
Mounting the Smart Sensor
Follow these instructions for mounting the sensor on a tripod or mast.
1. To mount the sensor on a tripod or mast, place the U-bolt around
the pole so that its two ends extend through the holes in the
mounting base. Loosely secure with the flat washers, lock washers,
and hex nuts.
2. Raise the anemometer to the desired height on the pole and swivel it
so the anemometer arm is pointing north.
3. Using an adjustable wrench or 7/16 inch wrench, tighten the hex
nuts until the anemometer is firmly fastened on the pole.
