OK, I'm biting. What would you expect to see on a PM2 for TDS of 0 or TDS of 1? I realize this technology would be cool/laziness, but by the time I find out I'm over 0 I am usually at 15 or so.
PM2 reads the conductivity of the water, not TDS however, there is a relationship between the 2 measurements. Divide the Conductivity reading on MS/cm2 by 2 and you get TDS. For example, if you setup your PM2 to the low range, divide the reading by 2 and you have TDS.
