3.0 UNPACKING THE
ResponseONE
The
ResponseONE
comes in a custom shipping carton. Carefully
inspect the instrument when first unpacking and report any visible
damage to your YOUNG supplier. Be sure to retain the bird spikes
and orientation ring for use.

ResponseONE
Features
The
ResponseONE
arrives fully calibrated and ready to use. As
supplied, the sensor is configured as follows:
FACTORY DEFAULT CONFIGURATION
Protocol:
RS-232 ASCII Continuous
Baud Rate:
9600
Wind Format:
Polar
Wind Units:
m/s, Degrees azimuth
Default connections are shown in APPENDIX A, FIGURE A1.
Other options are also described in APPENDIX A. These are
accomplished using the
ResponseONE
CONFIG
program which
is available at www.youngusa.com.
Note: Always connect and
bench test a complex system before installation in the field.
4.0 INSTALLATION
4.1 PLACEMENT
Proper instrument placement is important. Eddies from buildings,
trees, or other structures can influence measurements. Locate
the sensor well away from obstructions. As a general rule, air flow
around a structure is disturbed to 10 times the height of the structure
downwind and 1-1/2 times the height of the structure above the roof.

4.2 MOUNTING AND ALIGNMENT
The
ResponseONE
mounts on standard 1-inch (IPS) pipe. This is
commonly available steel pipe with an outside diameter of 1.34 inches
(34 mm). The pipe should be secured vertically. Place the orientation
ring over pipe end with guide pin facing up. Do not tighten clamps yet.
Most applications require aligning the wind sensor array to
geographic north (0 degrees). In this orientation the junction box
faces SOUTH (180 degrees). See the diagram in APPENDIX B for
details. Two methods are suggested below :
4.2.1 ORIENTATION USING KNOWN GEOGRAPHIC DATA
(PREFERRED)
Obtain accurate geographic data for the
installation site, this can be a topographic map, graphical
GPS map or detailed road map. Using the transducers
as a sighting aid, align the sensor with a remote feature
that represents the proper orientation. After alignment,
tighten the mounting post band clamp to secure the
position. DO NOT OVER-TIGHTEN. Engage orientation
ring pin with slot (Fig 4.2.3) in sensor base (under J-box).
Now tighten the band clamp on the orientation ring. If the
ResponseONE
is later removed, the orientation ring will
preserve the sensor alignment. Compass is NOT enabled
for this method.
