6. It is important that the RM Young model 05103 and 05305 AQ wind monitors be installed correctly to avoid bias in the wind measurements Using this SOP and the RM Young Model 05305 5 Wind Monitor AQ Manual from which much of the instructions were taken a person should be able to install the instrument correctly The sensor mounts on standard one inch pipe OD 35mm 1 34 An orientation ring is provided to ensure proper realignment and a stainless steel band clamp secures the mounting post assembly and orientation ring to the pipe A junction box at the base of the instrument merges the electrical connections and signal cable to the signal conditioning display and recording devices Initial installation is most easily done with two people one to adjust the orientation ring and the other to observe an indicating device such as a GPS to verify the orientation After initial installation and orientation the instrument can be removed and returned to its mounting without realigning the vane since the orientation ring preserves the wind direction reference Grounding the Wind Monitor is also important Without proper grounding static electrical charge can build up during certain atmospheric conditions and discharge through the transducers This discharge can potentially cause erroneous signals or transducer failure To direct the discharge away from the transducers the mounting post assembly in which the transducers are mounted is made with a
