a)
Stand at least 5 meters back from the Spidar. The further away from the Spidar you
are, the more accurate the result achieved.
b)
Position yourself to clearly observe the protruding rods vertically aligned, while
observing the jig aligned with a compass.
c)
Extend an imaginary line between two notches in the upper ring of the Spidar optical
head to measure the azimuth angle using a handheld compass.
d)
Take note of the compass azimuth value.
e)
The northing calibration procedure is very significant for accurate wind direction
measurements. It is highly recommended to verify the results by having a second person
repeat steps A through D (above) for confirmation.
E.
Meteorological Sensor
This section describes the installation of the combined temperature and precipitation
sensor (“met
sensor”) that comes with each
Spidar system.
a)
Unscrew four Allen screws fastening the brackets located at the back of the converter
and open the brackets.
b)
Position the met sensor sideways onto the tripod leg upper section on the wiper side to
avoid droplets being thrown onto it from the wiper arm movement.
c)
Close the brackets and screw the Allen screws back into place, leaving the screws
slightly loose for now.
d)
Plug the Met Mast into P4 in the connections panel (see below).
NOTE: This connection may be shared with the RS232 Y-cable connection to the Power
Controller.
