Resolution has a very specific meaning. To define a measuring
instrument you have to know the range, accuracy, repeatability or
precision, and resolution. The understand what these terms mean see
http://en.wikipedia.org/wiki/Accuracy_and_precision
http://www.firsttenangstroms.com/faq/Resolution.html also discusses the
different terms.
If your instrument has a readout that only reads integers, then the
resolution would likely be 1, in the case of a TDS ppm, or for
conductivity uS. If it has one digit after the decimal it would be .1
uS if it displays .1, .2, .3, .4 and so forth, but would be .5 uS if it
displays .0, .5, .1.0 only. Giving a result which is more precise than
the resolution of the instrument measuring it is meaningless. For
instance if you have a thermometer that reads in degrees F with no
decimal part, and it reads 72, you cannot claim that the temperature is
72.0 since the measurement could be off by .5 or even .999 degree.

Not sure what you mean by "resolution" ??

I have neve seen distilled water come in at 0. What are you testing
with and what is it's resolution?
