Well this is really interesting. Since the electrodes have about 2.3 or a bit more ounces of usable silver and they are still there although reduced in thickness a bit and since I know the PPM is not .3 but 20 because of independent lab tests, there can be no explanation other than I was mistaken in the estimated quantity produced.
See below for further comments.

The units are not triggered by static electricity unless one touches one of the electrodes when it is in open air and even then it is difficult to trigger. It requires a certain amount of resistance between electrodes to trigger. The generator circuit measures voltage drop across the resistance and compares it to the dial setting voltage. When they are the same the unit shuts off. > It should be possible to see if this is the problem by starting a > batch and turning on an ordinary electric drill nearby.

Nothing shuts it down except the resistance in the water or the use of an external resistor for calibration purposes.

Thanks for your offer but I don't need any troubleshooting help. This isn't rocket science. I'm capable of doing any necessary work. The units operate as designed.
