I recently bought a 43 range multimeter in my bid to learn how to
restore old radios, When testing a modern carbon film? resistor,
that's supposed to have a value of 2200 mega ohms, the display just
switches back and forth from 1.0 to 1.1 What does this mean? I'm
still learning on using the multimeter, by the way.

** You need to learn how to read resistor codes.

Cos there are no such resistors in radios or elsewhere.

Highest value you will likely ever see is 22 Mohms

- banded: red, red, blue.

OR, for really old ones

red body, red end and a blue dot in the middle.

2200Mohms? I suspect you've read that value incorrectly. You won't get
common resistors that high in value. Also, your average multimeter can
only read up to 20Mohms.

Also, if your display is only showing one decimal point then you have
the range set too high (or you are already on the lowest range
possible), in which case lower the range to get more resolution
(decimal places).

Try typing "multimeter tutorial" into Google and start surfing.

** To have " such " a resistor as the OP claimed he had, you need to show me
an example of a genuine, 2200 megohm resistor marked only with colour code.

Why? My quarrel wasn't with your stating that it was impossible for
the resistor that the OP was referring to to be 2G2R, it was with
your statement that: "there are no such resistors in radios or
elsewhere.", when clearly there are such resistors elsewhere.

As for the color code, it would be red red grey gold for +/- 5% or
red red grey silver for +/- 10%. ;)

** My word " such " refers to the resistor the OP claimed he had.

" Cos there are no such resistors ( as the one you are claiming you have) in
radios or elsewhere".

My comment was directed to the OP, who had apparently misread a colour code.
If he did not misread, then his alleged resistor has to comply with my
request above.


If YOU paid the proper attention to context and who is speaking to whom
about what, you just might make less dumb, autistic mistakes like this -
John.

But I doubt you have that ability.

Well, first of all. Is that meter capable of testing 2200 megs?

My guess it's not.
Secondly, make sure your fingers are not touching the probe tips.

Thirdly, May I suggest you're mistaken about the value of the
resistor under test ?

Me? LOL, had you but intelligently limited your statement to: ...
"there are no such resistors in radios", your goal of properly
chastising the OP would have been met and you'd have had no response
from me.

But, since you decided to include the: "or elsewhere" part, you
clearly were in error since 2G2 resistors _do_ exist outside of the
world of radio.

Why not just own up to your mistake instead of trying to be a Larkin
clone?

Now now John, lets me nice.

I know i'm trying very hard but, Eeyore brings out the best in me.
Oops, did I say that! :)

Actually, Phil is frequently right about many things - its his nasty
attitude a lot of the time that makes it such a result when someone catches
him in the wrong.
