Determine the position of
true
north and align the Wind Direction sensor to
this bearing, carefully following the instructions given in Appendix B.
5.
After the sensor is correctly aligned, fully tighten the lower clamp so that the
Wind sentry is secure. Double check that the direction sensor is still pointing to
true north.
You will need to connect the Wind Sentry into the datalogger. The Wind Sentry is
supplied with a 3 metre length of cable, pre-wired into its junction box and ready
for connection to the datalogger. Take the cable through one of the smaller cable
entry glands on the lower face of the enclosure, and wire into the datalogger
terminals as indicated below.
Other lengths of cable for your specific installation can be supplied to order by
Campbell Scientific. If you are using your own cable it must match the
specifications set out in the Wind Sentry manual. Remove the existing cable from
the Wind sentry junction box, carefully noting the wire colours/connection
position, and wire up the replacement cable using the old cable as a template.
Never connect an additional piece of cable to existing cable,
as this may cause errors and sealing problems.

4.3 Optional Sensor Connections
4.3.1 Installing the Optional Raingauge
In addition to the standard sensors provided with the Basic Weather Station, you
may wish to fit the ARG100 Tipping Bucket Raingauge. Wiring and program
details for the ARG100 raingauge are discussed in Appendix A.
See the separate ARG100 manual for full installation, operational details and
specifications.
4.3.2 Installing the Optional Radiation Sensor
In addition to the standard sensors provided with the Basic Weather Station, you
may wish to fit the CS300 Radiation Sensor. This sensor is required to obtain
meaningful Evapotransporation data. Wiring and program details for the CS300
Radiation Sensor are discussed in Appendix A. A suitable cross arm to support the
sensor can be obtained from Campbell Scientific.
