2200C AND DRIVER

Click here for technical support and drivers. Posted by zvi kaufman on Sep 09, The experienced application scientists and analysts at LI-COR are committed to providing the highest level of customer service and support. The line sensor technique relies on direct solar radiation and necessitates waiting for the sun angle to change in order to determine canopy interceptance at several angles. Check the Change Sensor check box. Measure a number of X, Z coordinates meters to characterize the vertical profile, perpendicular to the centerline, of the hedge.

Want to tell us more? First, a view cap should be used to mask the portion of the sky that contains the sun. Q How short can a canopy be and still get good measurements? The LAI value is foliage density.

LAI-2200C Plant Canopy Analyzer

FV is used to put everything together, do the scattering corrections, and compute final results. 22200c on, you will use these markers and eventually delete them. Random leaf positioning is assumed, implying a certain amount of leaf overlap.

Click OK when finished. The file header is presented: Did you find this helpful? Open the data file in the FV software. This field indicates which sensors were used to record the data and the name of the wand used.

How can ajd be resolved. How to remove scattered radiation in gap fraction measurements? Centering item on glass. ComiXology Thousands of Digital Comics. Turn the scanner so that the top is up. Place the desired view caps same size over the lenses of two optical sensors see chapters 4 and 6.

Q How can it correctly measure leaf area if the sensor can’t see all the leaves, or if the leaves overlap? Would you like to tell us about a lower price?

Canopy structure measurement by gap fraction analysis using commercial instrumentation. Make an above-canopy reading, multiple below-canopy readings, and a second above-canopy reading.

Masked rings are ignored when LAI is computed. Q At the location where my research is conducted, it is almost never cloudy.

A View caps can be used to prevent the sensor from seeing in a particular direction, allowing readings to be made near the edge of a plot, and reducing the total plot size necessary. Hold the optical sensor below the canopy level and oriented in the ajd direction as the above-canopy reading was and press the LOG button to record a Below reading.

Try going to Hp solutions website and download the updated drivers for windows 7. Designed by both scientists and engineers to provide quick and accurate results, as well as advanced processing options. An instrument for indirect measurement of canopy architecture. It consistently outperforms other methods such as Ceptometry and Hemispherical Photography in terms of flexibility, advanced features, accuracy, and ease of use.

We recommend that you do “Match Method 1” and make a match file for your two sensors. These procedures are referenced from various locations in adn manual.

The randomness assumption is clearly wrong when considering the entire field, but is much better when considering just one row.
