Contrast Adjustment for the LI-1400 DataLogger Display

Contrast Adjustment for the LI-1400 DataLogger Display

The display on the LI-1400 DataLogger may (rarely) become difficult to read due to a change in the display contrast. If this happens, the contrast for the LI-1400’s display can be adjusted  in hardware with a small potentiometer inside the instrument case. To adjust the contrast:

  1. Remove the six Phillips head screws from the back of the case and gently separate the two case halves. Note that the two case halves are tethered together by a pair of ribbon…

Daily Light Integral (DLI) measurement using LI-COR Light Sensors

Daily Light Integral (DLI) measurement using LI-COR Light Sensors

Definition of DLI

The daily light integral (DLI) is a measure of the amount of light received in a single day in a particular area. For example, the number of moles of Photosynthetically Active Radiation (PAR) photons received during a single day in a square meter, or: mol m-2 d-1. Another example is  the total solar radiation received during a single day in a square meter, or: W m-2. Depending on the application or research question the time integral of…

Right sensor, wrong multiplier?

Right sensor, wrong multiplier?

When working with your LI-COR light sensors, it’s easy to swap sensors from one instrument or channel to another. If you do this, it is important to update the calibration multipliers in order to record correct data. If you forget to update the multipliers, the data must be corrected to reflect the actual multiplier for the sensor. Fortunately, the procedure…

Turn Ons and Turn Offs

Turn Ons and Turn Offs

The LI-1400 Datalogger is often used for collecting environmental data using a variety of LI-COR Biosciences sensors. These include the LI-190 Quantum Sensor, the LI-192 Underwater Quantum Sensor, the LI-193 Spherical Quantum Sensor, and the LI-200 Pyranometer, among others. You can either program their LI-1400 to collect data automatically or set it up to collect data manually.

The LI-1400 has a power-saving mode to help conserve the batteries by…
