4. Vertical Mast not included The Relative Humidity sensor should be mounted in a sheltered area preferably on the north side of a building under the eaves to prevent sun heated air from rising up the side of the building and affecting the relative humidity at the sensor Mounting the humidity sensor in a self aspirating radiation shield provides an excellent way of sheltering the sensor from solar radiation and rain and allows for a convenient way to mount the sensor on a mast or the side of a building The relative humidity sensor is supplied with a standard 50 foot cable The cable provided is a 22 gauge 2 conductor shielded cable with a ground drain lead If additional cable is required a good Columbia Weather Systems Inc Capricorn 2000EX Weather Station 35 splice and waterproof insulation are essential merely twisting the respective wires together is not adequate Once the sensor has been placed route the cable back to the Control Module It may be convenient to combine this step with routing the wind sensor cable Using a small straight screw driver attach the humidity cable to the back of the Control Module as follows Red Wire Terminal 16 Bare Wire Terminal 17 Black Wire Terminal 18 Columbia Weather Systems Inc Capricorn 2000EX Weather Station 36 Installing the Wind Sensor Installing the Mast The Capricorn 2000EX will measure wind speeds of up to 160 mph 257 km h However unless t
