I went to the library, I got a book on electronics for inventors, and a book on electronics for hobbiests. Great for me, whoopdy doo for you.
Each book had a chart in it, that gave capacitor code reading a whole new meaning to the word confusing.
One was fairly clear, It has little pictures of ceramic discs that have lots of different things written on them and says, the markings will vary with the manufacturer...and explains the digit 1 digit 2 digit 3 and the multiplier thing...
The other defined a couple of types, that are usually fairly specific in their markings, but the rest are not hard to figure out, but its up to me to decifer.
K. I have a small pile of little ceramic discs, and I need a .1uf and a 50uf; but with everything from 222k to 104z on them. The inventor book says that capacitors are usually marked with pf.. Great for you, whoopdy do for me.
Well lets see if that's true----- a 104 would be a .000104uf and a 222 would be a .000222uf if I am getting my math right.
I am not really sure about my coding ability for some reason, so I am seriously concidering buying a capacitance meter.
But then again, I have heard stories about these also... That some are about as useful as the code sheet.
So what is the buzz on these "capacitance meters" anyway? Are they a waste of my time, and a codesheet with buttons? Or are they a "good investment" that will tell me when I "hit a .01uf" in my testing of the pile of small discs?
