3. Background Collection with PRM
The small test chamber that is supplied with the LISST-200X, described on page 10,
cannot be used with the PRM installed. Instead, you must immerse the head of the
LISST-200X in a suitable container of water.
1 Use a clean container and, as with any background measurement, clean,
bubble-free water.
2 Clean the parts of the LISST-200X housing that will be immersed, so
contamination shed by the instrument will not degrade the background.
3 Collect the background using the standard procedure, as described on page 13.
The instrument should be configured for use with the PRM prior to collecting a
background. If the instrument has been configured properly, it will indicate that
the PRM is installed in the legend of the background plot.
4. Removing the PRM
1
•
Clean the LISST-200X optics head and PRM components to remove any
large debris that could scratch the glass windows or cylinder when the PRM
is removed.
•
It may be necessary to remove any hard growth, such as barnacles, before
removing the PRM.
Be careful not to scratch the glass surfaces.
2
•
Remove the two 4-40 x 7/8 long socket head cap screws from the PRM plug
using a 3/32
” ball driver or Allen wrench.
