O2 analyzer question

[rjack321]

Yes my bad. I kept trying to think of the full name for "the pot" and finally gave up and called it by the AC version name. Wasn't intentional.

I still don't think turning a peice of life support equipment into a boat electronics troubleshooting device is a good idea. You can get multimeters from harbor freight for $2.99 Less than the cost of your very limited multimeter's parts

So don't bother mucking about making potential short circuits in your o2 analyzer by putting leads and extra switches in there.

English is not Mirrorcraft's native language, so you need to insert the punctuation and read it a few times to make sense of it.

Words are easy, but fitting them in a sentence is hard for non native persons.

He's a jarhead (according to his profile) and so am I. His location is Kentucky and I just made an asumption that he could explain what he was trying to say, my bad.

That is why the rheostat is used for home light dimmers, etc. It won't burn your house down.

You were doing good up to here..

A household light dimmer is actually a triac (or SCR pair) gated by a RC circuit that is controlled by a potentiometer. I don't doubt that decades ago early dimmers were rheostats.

It seems like there are fewer and fewer goodies at Radio Shack every year.

I agree that for the price of a compact multimeter complicating the O2 analyzer is unwise.
