[\quote]Precision and accuracy are two entirely different things.If you wanted to measure the length of something with a yardstick, which would be more precise, a yardstick with only inch markings, or one with markings every 1/8th of an inch. That,s a difference in precision.Now consider a yardstick that was actually 37 inches long but was divided into 36 parts graduated in 1/8th inches. That would have the same precision, but would be less accurate.Do you see the difference between precision and accuracy?So you should connect a precision (and accurate) meter between your power supply and your anode.

I would think that as long as you check the accuracy initially against a known measuring device and adjust for any inconsistency, making good colloidal silver is very possible.No, the accuracy of the SilverTron is within 2% of indicated value.You are also confusing set point with accuracy. SilverTrons have 15 setpoints for current spaced in 1 ma increments.Precision and accuracy are two entirely different things.The meters in the lab power supplies with two digits of display past the decimal point are +- 1 digit. So if it reads .01, it might be .005 or it might be .015. That is not precise enough for low value currents. 0.005 might display as .01. .015 might display as .02 or might display as .01.If you wanted to measure the length of something with a yardstick, which would be more precise, a yardstick with only inch markings, or one with markings every 1/8th of an inch.

Just ordered a regulator. Might be some time before it arrives, though.

The instructions should have been proof-read before publishing, but I don't think it will be a problem. Anyway, I'll be using unit over the coming week-end and get back with the verdict.
