Ivan,
In the comparison of PWT -- TDS readings I posted on 11/18, the TDS readings
are what the meter measured . What I multiplied by .57 was the raw reading of
the PWT. Thus:
PWT TDS
30 x .57 = 17.10 16
19.49 x .57 == 11.11 10
27.49 x .57 = 15.67 14
For the PWT results: where the third decimal place was more than 5, I rounded
up.
In response to my posting, someone responded that you had changed the
multiplier from .57 to 1.2 Is this correct?
I believe there are a good number of non-technical types like me on the list
who would find an explanation by you of how to achieve accurate PWT readings
as useful as are most of your other posts.
George
