Errrr, could you expound just a bit on how one would go about varying the
exposed surfaces in such a way as to calibrate the load? Your answer was
typical of a great many of those on RCM, lately. It seems like some
responders just like to see their names on the PC rather than offer any
thought-out, workable, advice. Someone asks a fairly specific question and
then they get a ration of BS from the responder. Sorta like: The man asked
how to make a wheel of a certain size and you told him to go chop down a
tree!

I can see what David's talking about. It's probably a bit more
complicated than I'd want to use for this task, but it's still a
worthwhile idea. As I see it you drive a car alternator using a three
phase motor and connect the alternator's output wires to a pair of
rectangular electrodes which can be lowered into the salt solution. The
further you lower them, the greater the current drawn from the
alternator. I assume that you measure the load by using the voltage and
current at the motor. Is that right?

Best wishes,
