•
Insert a white PRM End Plug under one end of the PRM Plate to lift the plate
up to the upper window.
•
Insert the second PRM End Plug.
Before installing the screws into the PRM Plugs to lock them in place, we
recommend checking the clean water background, as described next.

•
Check the Clean Water Background using the standard procedure described
on page 29. The results should be close to the factory values. However, they
may not receive a PASS result because of the instrument being in air.
•
WARNING: A background performed in air is not acceptable for particle
measurements. A new background with clean water must be performed
before deploying the instrument.
•
If the background does not look good, remove the PRM, clean the glass
surfaces and re-install the PRM until an acceptable background is obtained.

•
Install the two 4-40 x 7/8 socket head cap screws into the PRM Plug using a
3/32” Allen wrench to lock the PRM assembly to the LISST-200X.
