Getting Started
Contents of shipping

Please check that the following items have been included in the LISST-
25X shipping case:
1.
LISST-25X instrument
2.
Operating Manual with software disk.
3.

Horizontal test chamber
The LISST-25X Suspended Sediment Sensor is shipped ready to deploy.
It comes pre-programmed and in “sleep” mode.
Step 1: Remove
Instrument from
shipping case
Begin by removing the two white plastic instrument stands and set them
on a flat working surface. Remove the LISST-25X from its case and set it
on the stands. The LISST-25X has two distinct ends that are referred to
as the Optics endcap and the Connector endcap. The connector endcap
has an underwater connector that is used for communication and external
power. The internal batteries are mounted to a removable board that is
accessed by unscrewing the connector endcap. The optics endcap contains
the optical windows that the laser beam passes through to take a
measurement. The internal optics and electronics are mounted to the
inside of this endcap.
Step 2: Install test
chamber
Remove horizontal test chamber from the shipping container. This test
chamber allows the LISST-25X to be used and tested in the laboratory.
Insert the optics end of the instrument into the chamber. Fill the chamber
with clean filtered water. Make sure there are no bubbles attached to the
windows.
