Fresh Data Every Morning

Fresh Data Every Morning

There’s nothing like a fresh download of data to get your day started. The Internet of things has made it possible for you to download your data automatically from your Eddy Covariance measurement system directly to your computer. Using wired Internet, or cellular or satellite communications, your measurement system can be remotely accessed from the comfort of your office or home. After you have set up remote access, here is a quick tip that can help you reduce…

Sealing the LI-6400XT Leaf Chamber Around Narrow Cylindrical Leaves

Sealing the LI-6400XT Leaf Chamber Around Narrow Cylindrical Leaves

The standard gaskets on the LI-6400XT leaf chamber work well to provide a good seal around a variety of typical broad-leaved plant material, and specialized gaskets are available to accommodate very thick or succulent plant material (thick gasket kit p/n 6400-37). However, with both the standard and specialized gaskets it can be difficult to get a good seal around narrow cylindrical leaves in the 1.5 to 3 mm diameter range.

Image A shows a 2 mm diameter wire clamped between…

How to Interpret the Diagnostic Values from the LI-7500A and LI-7200 CO2/H2O Gas Analyzers

How to Interpret the Diagnostic Values from the LI-7500A and LI-7200 CO2/H2O Gas Analyzers

The diagnostic values output by the LI-7500A and LI-7200 CO2/H2O gas analyzers indicate whether or not your instruments are working normally, and what might have gone wrong in case of  a malfunction. Here are the two steps for interpreting the diagnostic values:

1.  Convert the diagnostic values from decimal to binary format

The LI-7500A and LI-7200 diagnostic values are labeled as “Diagnostic Value” in their outputs.  You can use the method of division by two to manually convert them from…

Troubleshooting Ethernet Connectivity Issues with LI-COR Gas Analyzers

Troubleshooting Ethernet Connectivity Issues with LI-COR Gas Analyzers

Newer generations of LI-COR gas analyzers are Internet Protocol (IP) enabled devices that enable remote connectivity over wired or wireless networks. Below are some tips to troubleshoot Ethernet connectivity issues when connecting to an instrument directly through Ethernet or over a network.

1.  Using a wired and a wireless network at the same time can make it difficult for the computer to find a device, because it is on two different networks at the same time.  The wireless connection in…

Recomputing LI-6400/XT data sets generated with older software versions

Recomputing LI-6400/XT data sets generated with older software versions

This Tech Tip describes different approaches that can be followed to recompute LI-6400/XT data generated with older versions of OPEN software.

First, in order to RECOMPUTE data you must have the essential variables logged in your data file.  Though possible, it is rarely a good idea to remove essential variables from your log list.  You should proceed carefully when you receive software warnings concerning essential variables.

If you have all variables needed to recompute, you have several options:

1.  Create…
