Changing Seasons With Your Photosynthesis System: Tips and Tricks

As the seasons change, it’s always a good practice to give your instrumentation some much-needed attention and routine maintenance. Below is a list of tips to help you get your LI-6800 or LI-6400/XT photosynthesis system ready for a new season of measurements.

LI-6800 Portable Photosynthesis System

  • Check your software version(s) and update to the latest instrument software, if necessary.
  • Check when the instrument was last factory-calibrated, noting the recommended frequency.
  • Check and replace the console air filter…

Using a Longer Cable for the External Quantum Sensor on the LI-6800

Using a Longer Cable for the External Quantum Sensor on the LI-6800

The standard external quantum sensor (LI-190R) provided with the LI-6800 sensor head (LI-6850) has a 12 inch (30.5 cm) cable terminated with a 3.5 mm audio plug.  For some applications, it may be desirable to place an external quantum sensor at a greater distance from the sensor head. For these applications, an audio plug adapter can be used in conjunction with another LI-190R quantum sensor with a longer cable. LI-190R sensors are available in cable lengths of 2m, 5m, 15m…

Resolving a Leak Issue With the LI-6800

Resolving a Leak Issue With the LI-6800

Leaks will get your attention by causing a leak/flow test failure (Start Up->Warmup/System Tests), low ‘Flow’ reading (mass flow to chamber in the diagram), low ‘Flow_s’ or ’Flow_r’ reading (flow through the sample/reference gas analyzer). The following three warning messages may appear on the upper left corner of the display: ‘Console flow leak?’, ‘Flow_s low’, ‘Flow_r low’ (see Table 5-2 on the page 5-4 of the LI-6800 manual for more details).

  1. If you can achieve ‘Flow’ setpoint, but…

How to Change Metadata in EddyPro Software

How to Change Metadata in EddyPro Software

Mistakes happen. During the busy hustle of an eddy covariance installation, you might accidentally enter some metadata values incorrectly in the LI-7500RS/LI-7500DS/LI-7200RS Windows Interface Software. For example, you could set the canopy height to 2.6m instead of 6.2m, or you could incorrectly hear the sensor separation numbers as they’re being shouted down from the tower. You might not notice the discrepancy for a while, either. Fortunately EddyPro® Software makes it easy to edit the metadata file and reprocess all of…
