Voltage is calculated by measuring the current through a known resistance (10 megOhms or whatever). But maybe you missed the point where Trem said that his unit is constant current. That is, the voltage starts out high to push as much current through the unit as is possible given the very high resistance of distilled water. Once the current gets to the set point (equals the designed-in constant current limit), then the voltage across the electrodes starts to drop. It's this dropping voltage that eventually triggers the shut-off mechanism. Trem's unit does compensate for DW variations, automatically, through it's constant-current operation. (And the unit even tells you if your DW is pure enough to make good CS.) -- Dean -- from (almost) Des Moines -- KB0ZDF -- The silver-list is a moderated forum for discussion of colloidal silver.
