warning icon, similar to the one pictured on the left.
In the following these error messages are described in detail, together
with their solutions.

LISST-Infinite Dilution Chamber did not fill.
Clean Water Tank may be empty. Readings
will resume automatically after Tank is filled. This error can stem from 2 factors:
1) The dilution chamber is empty
because the clean water tank is
empty. Check that the clean water
tank is full. Check that the hose
connecting the clean water tank to
the instrument is not obstructed and
that it has no kinks. Check that the
outflow from the clean water tank is
open.
2) Upon start of sampling procedure the
dilution chamber drains a small
amount of water. If it does not drain
(e.g. if the drain tubes are plugged, or
the pinch valves malfunctioning), it
will return this error. Check that the
drain hose from the dilution chamber
is not obstructed, that it drains freely
to atmospheric pressure, and that the
pinch valves are working.

sensor may require cleaning. System will The optical water level sensor in the dilution
