Andy,

Is the ring-down-time normal.  If not, then the optics need cleaning.  There
are cleaning instructions on the LGR website.

Hi all,

Have any of you LGR DLT100 liquid water analyzer owners taken it upon
yourselves to attempt maintenance (beyond septum, filter, syringe)? Anybody
know the software password? I like our LGR instrument. It is generally very
reliable and provides wonderful dD data. We have had (for the second time in
the last six months) a radical drop in water quantity. The first time, one
of the two valves on the inside, malfunctioned. The entire instrument went
back to LGR, was repaired, and ran until recently. Now, with a lack of
response from LGR for help, I am getting ready to dive in. LGR is very
secretive when it comes to this instrument which makes it very difficult to
do-it-yourself. Thoughts? Thank you.
