dknguyen said:Can't tell you why the meter is this way, but it makes sense if the meter would be damaged, since AC has zero DC (no damage if measuring DC) and DC can measure DC (duh!). So if you measured DC first you can't go wrong. AC on the other hand might be damaged if you try and measure DC with it, so you use DC (which doesn't get damaged either way) to check that there is zero DC before you try and measure AC.
Dean Huster said:Most good analog meters (Simpson 260, Triplett 630) are set up for an "output" mode with a DC blocking capacitor in series for measuring AC voltages in the presence of large DC levels.

Dean Huster said:Nigel, it would be political and career disaster if we were to treat male and female students differently. Having separate contests would invite so many lawsuits it would make your head spin.
Dean Huster said:I find it interesting though that you're comparing physical events for the male/female challenge instead of mental events, which electronics (and chess, Scrabble, cribbage, Canasta, etc.) is. I don't find that gender ever affects performance in this area as long as the person, male or female, has the right attitude and reason for being in school.
I agree, I think that's one of the largest problems in our society at the moment, there's too much talk of so called equal opportunities and treating everyone the sam which fails to note that everyone is different.Nigel Goodwin said:My point was simply that male and female aren't the same, and rules insisting they are make no sense.
Not only physical training but most of the boys won't reach their full physical strength until they're in their 20s.As for physical strength, my daughter is 17 years old, small and slim, yet is probably stronger than 90% of the boys in her school - and could probably out fight even more than that?. It's all a matter of training and skill, up to a certain point - then the male physical attributes surpass the female ones.
In my work, I use my trusty old AVO8 about once a month
