LI-COR LI-6400 Installation And Operational Instructions

6400-18
RGB Light Source
Installation and Operational Instructions
The 6400-18 RGB Light Source is designed to be used with the 6400-17 Whole Plant
Arabidopsis (WPA) Chamber, or with the LI-6400XT and any clear-topped chamber. The
LED calibration is retained in the light source, making it possible to switch from instrument
to instrument without the need to enter calibration constants. The red, green and blue
LEDs can be independently adjusted to allow users to select any desired color combina-
tion. Photosynthetic response differs with illumination wavelength, and is explained in
more detail in Application Note 5.
The assembly requires a Phillips head screwdriver, and takes about 15 minutes to com-
plete.

Follow these steps to install the 6400-18:

I
1. Install the 6400-17 WPA Chamber as per the instructions included with the 6400-17.
2. Remove the 4 Phillips head screws on the bottom of the RGB Light Source. Make sure
that there is a Propafilm covering over the aperture on top of the WPA top plate. With
the Propafilm facing the bottom of the RGB Light Source, attach the WPA top plate to
the bottom of the light source using the 4 Phillips head screws (Figure 1).
3. Connect one end of the gray control cable to the Control connector on the side of the
light source, and the other end to the 37-pin Auxiliary connector on the LI-6400/LI-
6400XT console (Figure 2).
