Rotate the tightening nut for proper tension in order to reduce stress from the chassis. Figure 26: Connect and Adjust Support Rod Repeat steps C + D for all 3 support rods.
Note that additional setbacks are required for sodars in order to prevent echoes from fixed objects from interfering with measurements. Spidar has the smallest cone angle of any remote sensor in the wind industry, allowing it to be sited closer to potential obstacles than any other device.
Elevation + Leveling This section describes how to set the height of the Spidar above level ground. The Spidar can be installed with a range of total system heights, from 912mm up to 1,305mm. The best height for your installation will depend on site conditions, particularly how level it is and the expected snowfall.
Figure 28: Remove Surface Obstructions Set Tripod Leg Length The Spidar can reach a maximum of 500mm ground clearance for normal operation by extending its telescoping legs. For installations in areas likely to experience heavy snowfall, the Spidar should be installed with maximum possible ground clearance to minimize potential obstruction by snow and ice.

Spidar User Manual Using the built-in Spirit Level, determine which tripod leg(s) require fine adjustment to bring the Spidar into plumb. Spidar is plumb when the spirit level air bubble is within the red circle. To make an adjustment, fold up the rubber ‘sock’ on the appropriate leg and rotate the base assembly on the fine adjustment nut to bring the Spidar to plumb.
Figure 37: Inserting Anchors Orientation This section describes how to determine the Spidar’s orientation relative to north, which is important to enable accurate wind direction measurements. The azimuth angle is the angular difference between compass north and the Spidar’s orientation, and should be measured during commissioning and recorded in the system’s configuration information.
NRG Systems Spidar User Manual Stand at least 5 meters back from the Spidar. The further away from the Spidar you are, the more accurate the result achieved. Position yourself to clearly observe the protruding rods vertically aligned, while observing the jig aligned with a compass.

The quality is a number between 0-100 Spidar Data Filtering Each Spidar wind speed measurement is accompanied by a quality score (Q value). This is a number between 0 (lowest confidence) to 100 (highest confidence) that is determined based on a combination of several parameters.
NRG Systems Spidar User Manual Data Quality Indicator Inputs (1) Percentage of raw real time results used to calculate the 10 minute average. (2) Correlation level of the current measurement to other 10 minute measurements in close measurement heights/ranges and close time stamps.
Page 62
NRG Systems Spidar User Manual • The quality score does not correspond directly to data availability (i.e. when using filter of quality score >=20 it does not mean that you have filtered out 20% of the data!) • An optimal quality threshold is both site and customer dependent – so there is not a standard value that is optimal in all cases.
It may therefore be necessary to adjust the time stamp to account for these differences. A simple way to check that the Spidar and tower data are aligned is to examine a time series plot of the wind speeds.
An important aspect of a Spidar-tower correlation study is the average wind speed comparison. While the correlation coefficient is an excellent measure of how well the two data sets track one another, the agreement in average wind speed is also a key factor in assessing the quality of the Spidar-tower comparison.
The wind rose is a common method of representing wind direction data. It allows the prevailing wind directions to be easily determined and they provide information about how variable the wind direction is at the site. In this section, the wind rose as determined by the Spidar and met tower wind vane are compared.
