Hi Ken,
I brewed EIS yesterday and got 6ppm overnight for one gallon. This morning I wanted to increase the ppm, washed the electrodes and set the turbo generator to manual and dc modes. When I turned the machines on, there was no green light. Even when I cupped my hand around the generator to make it dark so I could see the light, still, no light. Please help me with this. Thanks. Melly
