LI-COR LI-6800 Installation Manual

LI-6800 6×6 cm Leaf Chamber
The 6×6 cm Leaf Chamber is for large leaves. This doc-
ument provides installaion instructions for the large leaf
chamber. If the leaf fills less than half the chamber, we
recommend using the 3×3 cm chamber instead.
Detach the chamber from the head
Six screws will be removed to detach a chamber — two on
the connector cover, two on the latch mechanism, and two
that hold the chamber to the head.
Caution: Power off the instrument before following these
procedures.
Remove the two cover screws and the connector
1
cover from the bottom of the head.
2 Unplug the cables from the cable bulkhead (i.e.,
LI-190R, leaf temperature thermocouple, and light
source).
Position the chamber latch in the parked position and
3
remove the two latch screws.
4 Loosen both of the captive chamber screws until the
chamber is free of the head.
Separate the chamber from the head.

Warning: Do not attempt to operate the mixing fan
without a chamber in place.
While the chamber is removed from the head, inspect the
Air Filters and Dust Trap. Clear any dust or debris before attach-
ing a chamber.
