Hi Margaret, If you can locate an LM 317T and a 750 ohm resistor connected from ADJ to OUT it will regulate to 1.6 ma.
Look at my web site and see the current and voltage behavior with a current limiting device. www,hvacsilver.com Since you ar in "au" land I will see if I can get the silver and duplicate your work and then do a spectophotometric analysis to find out how close is your PWT . Past indications are that in the "no" TE zone the conductance and PPM are quite different. Maybe somebody there has a spect or ESI tester. As other have said, Peter has an agenda that is not appearant, so beware. "Ole Bob" -- The silver-list is a moderated forum for discussion of colloidal silver.
