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 (refer here),and check the sensor head dust trap and replace filters if they appear dirty or you are experiencing flow warning messages. Refer here for more information.
  • Clean the chamber windows and remove any debris. Replace Propafilm and leaf gaskets as necessary.
  • Check tubing quick connects and ensure they provide good connection. Replace if necessary (rare).
  • Clean o-rings and threads on scrubber tubes with a moist paper towel, according to these instructions.
  • Check and correctly position the leaf temperature thermocouple, if applicable.
  • Check the charge gauge of the batteries and recharge as necessary.
  • If you have access to calibration gases, check the zero and span of the analyzers.
  • Run the warmup and system tests and resolve any failures found.
