Microamps and Millivolts Measurements on UT61E
<< < (6/8) > >>
Gyro:
Measuring current with a DMM is kind of a last resort. As has been explained in several of the posts above, introducing the shunt resistors causes a voltage drop and changes circuit conditions - particularly troublesome in low voltage situations (eg. 3.3V or 1.8V logic supplies). Anything that involves breaking into the circuit is less than ideal.

With a bit of thought, you can often find one or more resistors in the circuit that you can measure the voltage across instead and derive the current by Ohm's law. A much more satisfactory solution all round.

I don't think he was calling you stupid. I'd like to think he was referring to the idea that a round-and-round discussion people get into when the question has been asked and answered but not agreed with or understood, so it keeps going like some debate when it's not a debate -- it's fact.

We're all ignorant of something, no shame in that, genius IQ or not. While this topic seems elementary to me (I've been an electronics hobbyist for most of my life and have owned dozens of meters), there are still many aspects of the field that are way above my head. Nobody just *knows* from the womb, and must learn it. If you're just starting out, you're not expected to know it. Just try not to come across like you don't believe them only because you don't understand it.

I am very ignorant on most topics and imagine my IQ is just high enough to be somewhat aware.  Maryilyn Vos Savant had talked about her upbringing during an interview and tells of her mom's response to her childhood questions.

I don't find a lot of people willing to do their own research.

Well I am sorry I might of come across that way. I don't think that at all.

Well like I've said, I've already journaled it and am going to get back to this thread. After I've gone through a few electronics books.  Believe me I have the motivation to learn -- I just needed to know if I should return this meter or not.. if it acting normal (and I got that answer here).   Regarding learning Electronics, I am just overwhelmed right now because there's so many books to choose from.   I guess I am going to start with Make:Electronics then Getting Started in Electronics.

The books I have seen recoommended to newbies:
0) Getting Started in Electronics
1) Make: Electronics
2) Electroncis for Beginners
3) All New Electronics Self-Teaching Guide
4) ARRL Handbook
5) ARRL's Understanding Basic Electronics
6) Practical Electronics for Inventors
7) The Art of Electronics

What order should I read them?  Which should I skip?  I have the Art of Electronics and it's too overwhelming for a beginner I think.
