Just got another email from TechSupport ... still not helpful really because this does not explain that the salt reading is a function of the V and A and T.
Normal voltage range should be 22.5 - 26.9 and
4.7-7.9 amperage
with a salt level between 2700-3400 ppm.
Anything
out side these ranges may indicate an issue with the system and would
requier service.
