.5 to 5 millimaps? It all depends on how much electrode you use and how far apart they are. The idea is to not exceed about 1 millimap per square inch of electrode. With constant stirring, you can go up to around 2 mA per and still get good results.
I've never done this, but as per observations taken as a whole..one could attach the electrodes to a ruler placed on a wide container. Starting with a single 9 v battery and the electrodes very close together, as soon as any activity is seen or current comes up to that 1 mA per Sq" if using an ammeter..start slowly moving the electrodes apart every few minutes to keep that activity or current reading more or less constant. It would be easier to see the intensity of a small light bulb or LED in series with one electrode and keep that constant. It's much harder [maybe impossible] to use too little current than it is to use too much, so keep the bulb or LED on the dim side. Running a resistor over to the other electrode lead can give an eyeball calibrator by momentarily shorting the LED to parallel hookup to get a reference brightness. That way you can get a numeric repeatable stopping point as read on the ruler with a literal 'handle' on the current draw. What that number 'means' is another question, but at least you can shoot for the same number and make something that pleases you every time. It's very important to keep the electrodes parallel so current density and ion discharge will be uniform. If anything, bend the tips slightly away from each other to limit edge discharge. With the container well lit, I've found that if I only see 'white wisps', I usually get a good batch. If I see the 'golden whisps'...way too much current. Lighting the container from the bottom eliminates glare. Using a smooth round container allows a microscope sort of view. [highly magnified] Harbor Freight sells digital multimeters for as little as $4 They work just fine. Another very simple thing to do is to get a current control diode with a rating suitable to your electrode size. [1 mA is safe with 6" electrodes] Hook that and an LED up in series with a wire that hangs near the other electrode lead. Short the LED over to parallel momentarily to get a visual idea of what max current looks like. When the LED gets 'that' bright, that's where ions emmission becomes linear [a starting point]... start a clock. If the LED starts out really dim, that means your water is good. I've made good 'manual operation' pocket generators for soldiers that way. [The electrodes can be inserted into a wound too] An interesting thing to discover is just how little contamination it takes to make a huge difference in water quality. Put the smallest amount of baking soda you can into the water and see the huge difference it makes. I mean, tiniest tip of a toothpick nearly invisible amount. A mere water spot [mineral deposit] on the container can make a difference. Clocks are useless if you don't know where you started from and the rates are always climbing faster and faster.
