Couldn't you use a current regulator, a current to voltage convertor, a diode, and a transitor to make the cs make automatically turn itself and keep a regulated current. Oh add a pot in there for current adjustment for regulator and one for the current to voltage convertor. Not sure on this

If instead you regulate the current so the voltage drops with increased conductivity, you can use a comparator to do the turning off part and dial in the desired voltage or use a series of switched zener diodes to establish the exact desired voltage for the comparator to use as a reference. The

I feel that Wayne is dead right in specifying the quantity voltage but the current will vary on other factors such as size of electrodes, distance apart, etc. I can't answer his exact question but I can indicate what I do for smaller runs which may help others. I make 900 ml (bit over 1 1/2

The $5 to $8 digital multimeter from harbor freight probably costs less than a panel meter, is already calibrated and has a variety of ranges. Just wire it in? ken At 01:22 PM 12/12/01 -0600, you wrote: Morning Bob, Terry, and the list, Often I find myself using my multi-meter to monitor CS

Morning Bob, Terry, and the list, Often I find myself using my multi-meter to monitor CS process. So I decided to add a permanent current meter to the generator. Likely I will use a panel meter, edge type. A digital meter would be nice and it could have multiple scales but one scale
