I. Instrument Mounting, Deployment Orientation,
Storage and Maintenance
This section contains information on mounting, storing and maintaining the LISST-200X.
Mount the
Instrument
Horizontal
The LISST-200X measures scattered light to obtain particle size
distributions. Therefore it is important to keep particles from sticking
to the window surface. The first line of defense it to keep the window
surface vertical by mounting the instrument horizontally. This is most
critical when the water motion is slow. When working in rivers or in a
towed or profiling application the orientation is not as critical.
The center section of the main pressure case has a slightly smaller
diameter than the ends. The smaller diameter section is the
suggested mounting area. The U-shaped mounting block provided
with the instrument fit this diameter and can be used for mounting the
instrument. The clamps supplied with the instrument can also be
used.
Spare clamps for mounting the instrument are available from
Sequoia.
Precautions for
Vertical
Mounting
If mounting the instrument vertical the optics endcap should always
face downwards. If the connector endcap faces downwards, and the
instrument is subjected to a bump or shock during deployment, the
Compact Flash Memory Card inside can come loose, making it
impossible to offload data.
Use the supplied U-shaped mounting blocks or the stainless steel
clamps with rubberized inserts for vertical mounting.
